Why it is still .Net Framework v.2

[MarkMindlin]

Hi there,

In Visual Studio 2013, Desktop 10.3, I created a standalone project for .Net Framework 3.5.(in VS: Project properties -> Application -> Target framework->3.5).

When I run it I see in the list of processes it runs as .Net Framework v.2

Why? (may be because this project has references to another my companie's old dlls). How to change it to 3.5?

Any help would be greatly appreciated.

I think that this is expected because both .NET 2.0 and .NET 3.5 use CLR 2 because Microsoft didn't release a CLR 3.0. A Microsoft Developer may be able to get you a more specific answer, but you can see in the image below that I get this same behavior in a pure C# application with No Esri Components. The application is compiled against .NET 3.5.
