Determine Installed Compact Frameworks (and SP) Version

Question

What's the best way to determine which version of the .NET Compact Frameworks (including Service Packs) is installed on a device through a .NET application.

Answer 1

Check out these blog posts by the .NET CF team:

Actually, those links will only work if you are already running in managed code. Take a look at this Google Groups post for details on the registry keys you need to look for.

Answer 2

Based up Scott's links, the information about the current CF version can be found in the registry of the device at:

HKEY_LOCAL_MACHINE\Software\Microsoft\.NETCompactFramework

Versions for CF 2.0 are:

CompactFrameworks 2.0 RTM - 2.0.5238.00
CompactFrameworks 2.0 SP1 - 2.0.6129.00
CompactFrameworks 2.0 SP2 - 2.0.7045.00
