"Best development platform ever invented"

What do you like best?

.Net and its companion languages like C# are unique as a developer platform and a runtime. I love the fact that .Net has a common runtime that supports several languages to be used to develop on top of it and the interoperability between those is absolutely flawless. The is made possible by the metadata that is included in the binaries that are compiled, which are called assemblies.

The other thing I love is the fact that the compiled binaries do not contain by default native code, but intermediate language code (which is binary, not text) that is just-in-time compiled to native on runtime. This is a very small performance penalty on application start-up (and the first time each method is used for the first time), but essentially makes applications multi-platform. In the end, native code is actually run, so performance is not an issue.

Yet another amazing aspect .Net has is the incredibly optimized garbage collector. This means that developers don't need to worry about managing object memory. There are no segmentation faults for trying to access already de-allocated memory. There are no memory leaks (strictly speaking that is - in practice, there still can be memory mismanagement by making bad use of static variables). As to the performance, while purists will stand by their highly optimized C and C++ code, for applications that have a lot of objects being created and disposed, the GC does represent an incredibly *better* performance than C and C++. I've already benchmarked this and the difference can be of something between 5x and 10x faster, where .Net solidly wins. Moreover, .Net manages very well the problem of memory fragmentation.

Finally, .Net supports some language features I absolutely became dependant on. Delegates are so much better than Java's anonymous interfaces. Properties are an incredibly better way to expose private state, that Getters and Setters. Generics are well implemented instead of being erasure generics.

Finally, there's the unique killer feature, LINQ - Language Integrated Query. Linq allows for expression trees to be written in the language of your choice (for instance C#) and have those expression trees be translated by database providers into optimized SQL queries to that database. This allows a whole new level of ORMs and a great example is Entity Framework. But this is just one of LINQ's many aspects. Depending on the context, the exact same LINQ, usually represented as a lambda expression, might be used as either an expression tree or an anonymous method. This means the same logic used to query a database can be used to query non-database things like lists of objects, XML, Json and so on. It is extremely versatile.

There are so many more things I absolutely love about .Net, but these are probably the main things.

What do you dislike?

The fact that in the past .Net was officially a Windows only proposition. In fact, .Net 4.5 is still only Windows. It kind of defeats one of its great characteristics, the fact that it is in theory multi-platform. However, there has been Mono, an alternative .Net implementation that wasn't supported by Microsoft and even better, .Net has been rebooted and a there is now .Net Core that is officially multi-platform. In practice, nowadays we can run .Net in a very broad range of devices ranging like macOS computers, Linux desktops and servers, iPhones and iPads, Android devices and Windows UWP, Even IOT devices, hologram and Xbox are supported now.

Recommendations to others considering the product

Do consider .Net Core. .Net Core is still not the complete framework, so it still misses some bits. If you need some more advanced features like AppDomains and more control over threads, you're out of luck with .Net Core and you will need the full framework like .Net 4.5. However, if you don't need those features, .Net Core is a supported multi-platform solution.

What business problems are you solving with the product? What benefits have you realized?

I've developed many line-of-business applications.

"Best .Net Update in Years"

What do you like best?

Great new features building on the already powerful framework of .NET. This version adds the async and await constructs, zip file handling, regex timeouts, and much more

What do you dislike?

The framework is so vast it is hard to tell what is new and little time saving features are not always advertised.

Recommendations to others considering the product

It is a vast and powerful framework but do not be intimidated by its size or complexity. Once you learn the basics, it is easy to pick up the time saving shortcuts. A quick web search usually leads to many others with similar questions on usage or problems

What business problems are you solving with the product? What benefits have you realized?

The .Net framework allows me to build high quality applications and focus on the differentiating business needs of our company rather than having to spend time writing boilerplate UI code, IO code, or other simple tasks.

"Ease of Use and Integration "

What do you like best?

The thing we like the best is the security it offers as we integrate into our application. It has a great ability for backwards compatibility within all our applications.

What do you dislike?

One thing that we tend to dislike is the actual upgrade process within our application, but I don't think that has anything to do with the .net framework itself more on how we architected each application. Some legacy code takes more of an effort to keep current.

Recommendations to others considering the product

.NET helps us with the reduction of developmental as well as cost in order for us to be an efficient and effective IT organization.

What business problems are you solving with the product? What benefits have you realized?

Some business benefits is .net's ability to handle many of our business processes, one of which includes the ease of deployment across all our applications. Being a government contractor security is a big thing with our company, and the .net framework provides that for us.

"5 years using product"

What do you like best?

4.5 introduced tons of performance and stability improvements to mature and well known .NET Framework technology.

The best features I like are:

Background garbage collection for servers

and

Ability to explicitly compact the large object heap (LOH) during garbage collection

What do you dislike?

Cross-Platform Development with the Portable Class Library.

Some features are available only when using Visual Studio 2013 or higher.

New reflection engine

Recommendations to others considering the product

.NET 4.5 and 4.6 are the most up to date versions of well known Microsoft development technology.

I'd highly recommend using it today due to:

* maturity of platform, language and tools;

* high number of developers familiar with the technology;

* high stability and robustness;

* unclear future of .NET 5 and next generations.

"Great platform for rapid application development"

What do you like best?

Very feature rich and flexible platform for development of cross-platform applications. You can use the language that is most comfortable to you, from VB.NET to C# - it's up to you. In addition, now with Microsoft's purchase of Xamarin, you can build thick-client, thin-client, or native mobile apps all using one familiar platform and framework. This gives you maximum flexibility with your development projects and ensures quicker time to market for your software and applications.

What do you dislike?

i think that the previous version of the .NET framework being a closed system was a negative, but this is being addressed with .NET Core 1.0. Opening the framework up to the community will only increase adoption and get more people on board.

What business problems are you solving with the product? What benefits have you realized?

We run a development shop that creates cross-platform applications. This includes web applications as well as native mobile applications. Our core competencies are on the .NET platform so we are looking forward to the new .NET Core. We have benefitted from being able to quickly build any type of application with standard technologies and consistency across our development teams. The tools that back the .NET platform, including Visual Studio and now Xamarin only help to make our jobs easier.

"A good framework, with its proprietary restrictions"

What do you like best?

I only write C# code (I love its syntax), but I really like the general idea to write different parts of a product in different languages. You can write a math library in F#, a GUI in C# and backend in VB and everything will work great together.

What do you dislike?

It is a Windows only framework, which disallow you to develop under *nix like system and then reduces the scalability of your code.

Recommendations to others considering the product

Always keep in mind that you won't be able to develop with .NET in non-Windows desktop environment. You can use Mono, which is not satisfactory enough.

What business problems are you solving with the product? What benefits have you realized?

I mostly use it for ASP.NET developing, UWP and trying Xamarin right now. It allows me to reduce number of programming languages I have to to in a full-stack developing.

".net 4.5 my preferred framework to develop web applications"

What do you like best?

There is a lot to like about .net 4.5 framework, it has made a lot of improvements since 4.0 such as:

Support for Windows Runtime

Support for Async Programming

Faster ASP.NET Startup

Better Data Access Support

.net 4.5 framework has a lot of builtin functionality and classes that can be used to speed up programming. I like the fact that as .net framework evolves they keep adding new functionalities and classes that is seen as a common need in the industry

.net 4.5 is a very mature framework finding documentation on classes and usage is easy to find not to mention tons of examples

What do you dislike?

Applications built on .net 4.5 could only be hosted on windows, this has been resolved in later release "Asp.NET Core".

Recommendations to others considering the product

.net 4.5 is a great framework to either start your development path or to switch to easily build robust applications. If you are however looking to build a cross platform web application, you should consider using Asp.NET Core framework instead of Asp.NET 4.5

What business problems are you solving with the product? What benefits have you realized?

I have mostly used .net 4.5 to building enterprise systems that implements Microservices Architecture to ensure that applications are built with scalability in mind.

"Async and await code markers my favourite feature!"

What do you like best?

My most favourite introduction is the async and await keywords. For years asynchronous programming has been complicated when it came to using preexisting async apis like TPL. Developers knew the benefit of writing code asynchronously but the complications it present when it came to using the tasks libraries and the new paradigms made it a bit difficult for some to adapt. With the advent of the async and await keyword though writing async code has never been easier. it's basically one of the simplest methods of writing such code in any language and the compiler itself handles all the other issues for you. Im also happy that they finally bundled compression/zip capabilities into the framework so we don't have to use external libraries anymore for such simple tasks.

What do you dislike?

The main issue I have had so far with .Net 4.5 it's ability to break existing apps that are running on older APIs. Microsoft has done reviews of several projects and setups and they have deemed that majority of projects wont have issues upgrading however there still stands a chance that several older apps will break once they are updated. I think it's paramount that Microsoft ensure that when they are deploying new features they ensure that they take key consideration in enforcing rules for backward compatibility as many developers and companies have existing infrastructure built on this framework and it's alot of technical debt to be fixing broken code due to a framework update.

What business problems are you solving with the product? What benefits have you realized?

The main problem this upgrade has solved is making sure my apps are more responsible and powerful. With the new async and await keywords writing async code has never been easier so my platform benefits from having tasks excecuted quickly has mutliple threads are handling tasks and certain long running queries don't block or make the app hang as the app can continue what it's doing while that task is processed in the background and that in itself makes my apps more responsive and user friendly.

"It's a bit out of date now."

What do you like best?

.Net 4.5 paved the way for massive changes in the framework ultimately leading to 4.7 and to .Net Core (which I love).

What do you dislike?

Nothing I really dislike, the 4.5 version of the framework just feels a bit cumbersome in some places now with the improvements in 4.6, 4.7 and Core

Recommendations to others considering the product

Get .Net Core instead, or at least get 4.7 or whatever the latest version is when you read this.

What business problems are you solving with the product? What benefits have you realized?

N/A - I use .Net Core.

"Great to create application, not as much for Web App"

What do you like best?

The .Net library is massive and help you save so much time when working on a project. Too bad thread safe collections aren't available out of the box to help you save even more time.

It has everything you need to create any size of application (from a tool to a massive application). So many connectors are available to interface your application with a Database.

What do you dislike?

For form applications, events handling should be easier and not require "delegates".

Microsoft should have also improved Visual Studio to provide the same features as Resharper.

Creating ASP.Net Websites is n't a enjoyable as other languages as PHP. You can clearly see that the language wasn't meant for Web applications first but was adapted which make it tricky out of the box. Probably using a framework will make it much easier.

Recommendations to others considering the product

Microsoft is started to release free developer version of Visual Studio / .NET, making it easy to install and try this developer environment. I prefer .NET solution over Java environment (my experience with Java is pretty limited though).

What business problems are you solving with the product? What benefits have you realized?

Develop any size of applications and organize your code properly so you can work as a team (coupled with Git for instance for source control).

"The Platform for Windows Phone"

What do you like best?

Microsoft's .NET Framework is a software framework that allows developers to create applications and programs for Windows products. Nowadays, this allows users to create apps that will run on all kinds of platforms: Windows Phone, Tablets, and Windows 10. I've used the .NET framework in the past in conjunction with Visual C++ to create desktop applications.

What do you dislike?

Microsoft's .NET in general was created with the idea of creating apps specifically for Windows. This is not ideal, if you plan on creating your application for other operating system (either desktop or mobile). For that reason, it is hard to recommend creating a project using the .NET framework exclusively.

Recommendations to others considering the product

If you are writing an application specifically for Windows, you should consider .NET.  However, if you want to be a bit more flexible and deploy to another operating system, I would look elsewhere.

What business problems are you solving with the product? What benefits have you realized?

I've used .NET 4.5 in a work environment mostly as a runtime executable to run other applications. I have used it briefly in the past to develop desktop applications (in conjunction with Visual C++), but my experience with .NET ends there.

"Vast improvement over .net 4.0"

What do you like best?

Support for Async and overall speed improvements have made this product a vast improvement over 4.0.

What do you dislike?

Had to update past Windows 8, which wasn't a huge deal, just a time burden for us.

Recommendations to others considering the product

Play around with it, if you are using 4.0 and are reluctant to move, this is a great time to do so. Speed of execution alone is worth the change.

What business problems are you solving with the product? What benefits have you realized?

Speed.....always the most important thing when pushing something to a customer. 4.5 has improved on that greatly.

"WPF opinions"

What do you like best?

.Net 4.5 adds many new great features such as Crytography, ADO,Net, Windows Presentation Foundation (WPF) and Windows workflow Foundation. I have made some great client based applications with WPF. The WPF feature allows for many options when creating an interface. It offer nice improvements for C# developers. It is just the latest and greatest release in the .Net library until 5.0 is released.

What do you dislike?

There are always comparability issues which limit upgrading from the older versions. .Net 4.5 does not support Windows CE.I have also noticed issues when interacting with Java.

Recommendations to others considering the product

Great amount of resources for the .Net library. Definitely worth using if you are writing a new application in C#.

What business problems are you solving with the product? What benefits have you realized?

.Net 4.5 was the solution when we needed an application requiring asynchronous file operations in multi-threaded environment.
