Programmatically check which versions of the .NET Compact Framework are installed

Question

I have a Windows Mobile application that was created for .NET CF 1.0. It is written in C #. How can this program check which versions of the .NET Compact Framework are installed on the device on which it is running?

Answer 1

It really depends on what you mean by "installed." If they were installed through a CAB file (the most common), the registry will HKEY_LOCAL_MACHINE\Software\Microsoft\.NETCompactFramework entries in HKEY_LOCAL_MACHINE\Software\Microsoft\.NETCompactFramework that you could check programmatically.
