i want to know which .net CLR version my application is using

i want to know which CLR version my application is using.

I "dont" want to use either clrver.exe or GetCORVersion(),GetRequestedRuntimeInfo(),GetRequestedRuntimeversion() as these ways are Visual Studio specific. Is there any .net framework related exe/dll/api which will give me CLR versions since i want to use the java language to know about it and need a way which also work when framework is present but not the VS. Registry key value will be a great option. i want o/p like clrver -all

Have you tried simply: Environment.Version

Maybe the RuntimeEnvironment.GetRuntimeDirectory Method?

EDIT: If you only have access to the registry (if your program is not a .NET one), I suggest you use this SO answer: How to detect what .NET Framework versions and service packs are installed?
