Where is .NET Framework 4.5 directory located?

I installed .NET Framework 4.5 on Windows 7 Enterprise SP1 64 bit. When I looked in C:\Windows\Microsoft.NET\Framework (Framework64) directory, I did not see any directory containing files of .NET Framework 4.5, just those:

• v1.0.3705
• v1.1.4322
• v2.0.50727
• v3.0
• v3.5
• v4.0.30319

Installing the .NET Framework 4.5 says:

The .NET Framework 4.5 replaces the .NET Framework 4. When you install the .NET Framework 4.5 on a system that has the .NET Framework 4 installed, the assemblies are replaced.

Thereby, 4.5's files are located in v4.0.30319 directory. Am I right?

Both 4.5 and 4.51 are in-place upgrades, which means they replace the previous version (4 or 4.5). The files are overwritten and these framework versions do not have their own directory but are stored in 'v4.0.30319'

So your assumption was absolutely correct.
