How can I enumerate all installed frameworks ...

.... programatically using C#?

Thanks.

There's nothing in .NET that does this.  AFAIK, you have to look at the
registry and what's actually installed on the disk.

There's a fairly good chunk of code that does that here:

Thanks Matt ... looks very hopeful (I haven't tried it yet).

I was able to establish the version in use with

System.Runtime.InteropServices.RuntimeEnvironment.GetSystemVersion();

which corresponds (I think) with the article's

System.Environment.Version.ToString();

If C# 4.0 is able to target multiple frameworks, I expected to be able to
establish the installed versions more ... readily perhaps (?).

Hello,

I was able to establish the version in use with

System.Environment.Version.ToString();

If C# 4.0 is able to target multiple frameworks, I expected to be able to
establish the installed versions more ... readily perhaps (?).

Multi targeting (which is really more a VS feature) means that you can
choose *at compile time* the version you are targeting. The resulting
application will run only against this version.

This is not the same than selecting at runtime against which version you'll
run (http://msdn.microsoft.com/en-us/library/9w519wzk.aspx). In all cases,
your app doesn't need to enumerate those versions as the version has to be
selected before your app can be started.

If you still need some help, your best bet is likely to explain first what
you are trying to do...
