Checking to ensure framework is installed

I'm writing an application in C# using the .Net framework. Whenever
the app is executed on a system without the framework installed, it
throws an exception which isn't particularly useful to the end-user.

How do I give the user a meaningful error message if the framework
isn't installed? I've come across a few .NET apps that give a
user-friendly error message to inform them that they need the
framework, but haven't found a way to duplicate it in my application.

I'm using #develop (http://www.icsharpcode.net/OpenSource/SD) as my
IDE.

Thanks in advance,

TEGS

Hmm ... I can only think of one way that it would be possible. You
could write a small bootstrap program in c++ that would simply take
care of detecting whether the framework is installed, if so, it
launches the managed .exe, else, uses win32 to display a nice error
message.

The other (easier) solution is to create an installer ... you can
create a dependency for the .net framework. If the client doesn't
have the framework, it will prompt them to download and install it.

Easy as pie,
