I have a project in Visual Studio. How can I find out which .NET Framework version it\'s for?
It's as easy as in your Visual studio.
Simple Right Click and go to Properties Option of any project on your Existing application and see the Application option on Left menu and then click on Application option see target Framework to see current Framework version .
Project Properties -> Compiler Tab -> Advanced Compile Options button
Project Properties -> Application Tab
With Respect to .NET Framework 4.6 and Visual Studio 2017 you can take the below steps:
You can't change the targeted version of either Windows or the .NET Framework if you create your project in Visual Studio 2013. That option is not available anymore.
