How to install .NET 4.5?

问题

I downloaded and install .NET 4.5 beta on windows 7, but not sure where it is installed.

1. Check C:\Windows\Microsoft.NET\Framework, can't find out folder for 4.5
2. Open VS 2010 and open property for one of project in a solution, there is no 4.5 in the list for Target Framework, only .Net Framework 4 there.

How to make sure the installation okay and how to use it?

回答1:

.NET 4.5 is an in place replacement for .NET 4.0 - that means that the assemblies are in the v4.0.xxx folder.

You can also find the assemblies in a reference assemblies folder:

C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework.
