How to identify that an assembly has been compiled with/for .NET 4.5, as opposed to .NET 4.0?

Question

I have some build agents that is building .NET code for us through a TeamCity setup, and I\'m beginning to wonder if despite the project settings, they\'re outputting .NET 4

Answer 1

The metadata version v4.0.30319 is for .Net 4.0. See here:
