How to avoid MissingMethodException?

If .NET 3.5 is installed, but not .NET 3.5 SP1, WaitHandle.WaitOne(int) throws a MissingMethodException. I'开发者_运维技巧d like to be notified earlier on if the correct version of the .NET libraries is not available, for example when the application is started. Is this possible?

Update: So my question question is twofold:

• a) How can I determine which version of the .NET library is required by an application?
• b) How can I determine the currently installed version of the .NET library?
