Question

I need to programatically determine whether .NET 3.5 is installed. I thought it would be easy:

<% Response.Write(Environment.Version.ToString()); %> 

Which returns ‘2.0.50727.1434’ so no such luck…

In my research I have that there are some rather obscure registry keys I can look at but I’m not sure if that is the route to go. Does anyone have any suggestions?

You could try:

static bool HasNet35() {     try     {         AppDomain.CurrentDomain.Load(             'System.Core, Version=3.5.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089');         return true;     }     catch     {         return false;     } } 

@Nick: Good question, I’ll try it in a bit.
