Is there a minimum .NET framework one must target with SDK 10.1?

I am working with Desktop Basic 10.1 and vb.net. What version of .NET framework should I target when compiling custom components in visual studio?

Are there any good references I should read about compiling arcobject custom components? I have spent days searching and still do not fully understand what I should be doing.

(In a previous thread I detailed the problem I am trying to fix: compiled code works on my PC but nobody elses. Debugger code works on all machines tested)



Thanks for any advice,

Tim
