There is a new feature available in Visual Studio 2015 and roslyn compiler – live code analyzers. Those can be used, to improve your code quality. Code analyzers can be installed via NuGet packages and if you want, you can also implement your own analyzers.
What are live code analyzers?
Analyzers are extensions that can be added to the Visual Studio project. They are available in Visual Studio 2015 with the Roslyn compiler and they analyze the code live and check if there are improvements. Live in that case means, that it finds issues as you type. Really cool feature!
