Specs
Ranked in these QuestionsQuestion Ranking
Pros
Pro Versatile
.NET offers rich functionality.
Pro Visual Studio
The Visual Studio IDE offers one of the best development environments. The Community Edition and Visual Studio Code can be used for free.
Pro Forms
Can be designed visually with the Visual Studio designer for traditional Windows forms, WPF, or Web forms.
Pro 3rd Party support
Lot's of tools and libraries available.
Pro Can be used in a variety of fields
With Xamarin for Mobile (ios, android),
with .net core asp for server (linux, windows),
with .net core for desktop (windows, mac),
with mono for desktop (windows, linux),
with blazor for web client with webassembly.
However, it is not considered top for any of those categories, but it is top choice for Windows desktop with .net framework and top choice for Unity.
.net 5 will unify frameworks similar to JVM (just one).
Pro Cross-Platform
Runs on Linux, Mac, and Windows.
Pro Supported By Microsoft
Constant updates and bug fixes to many popular frameworks, as well as great first-party support from Microsoft. This can be a con as well in certain circumstances.
Pro It is a C like language
Being a C like language counts in favor for it as a general purpose programming language, given the ease of using existing skills to pick up this language easily.
There are other superior languages that could be used as a general purpose, such as: F#, Haskell, but the complexity of those languages, being functional, make them strange to the usual C Syntax.
C# is better than C whenever garbage collection, Objects, classes, data access, are needed. But C is going to be the choice when hardware access and performance are paramount.
Pro Cross-platform
Compile app to run on different OSes.
Pro Sum types
V has sum types.
Pro GUI support
V comes with (simple) GUI support out of the box.
Pro Clear syntax
Highly understandable language.
Pro Safety
V is very safe.
Pro Fast like C
V is easier than C and fast like C.
Pro Closures
V has closures, which gives the user additional options and usefulness.
Pro Generics
V has generics.
Pro Supports concurrency and channels
Can run functions concurrently that communicate over channels.
Pro C Interop
Can import C libraries, structs, and headers.
Pro Fast compile times
Compiles programs fast, less waiting around, so more productive and fun.
Pro Lambdas
Supports using lambdas, which helps write more concise code without having to use so many lines.
Cons
Con Learning curve
For a beginner the .NET framework can be daunting, the rich functionality means that things often can be done in several ways.
Con Very large runtime
Cannot be used for embedded programming.
Con Microsoft will mess up with the Visual studio installation
And all of a sudden you'll need to reinstall the entire thing just because it stopped working.
Microsoft assumes that every workstation is connected to the Internet then it is always pushing updates.
Con .NET is a mess
Troublesome in regards to being Microsoft centric, updates, security, excessively large, cross-platform issues, etc...
Con Windows OS centric
Not very good at being a cross-platform programming language.
Con Strictly object oriented
Con Owned by Microsoft
And like always, Microsoft is to be avoided, no exceptions.
