Assembly.ImageRuntimeVersion Property
.NET Framework 4
Gets a string representing the version of the common language runtime (CLR) saved in the file containing the manifest.
Assembly: mscorlib (in mscorlib.dll)
For example, the value for the .NET Framework version 1.1 would be v1.1.4322. The binary files for that version would be located in the path %windir%\Microsoft.NET\Framework\v1.1.4322.
By default, ImageRuntimeVersion is set to the version of the CLR used to build the assembly. However, it might have been set to another value at compile time.
