No. It does not stand to reason.

Well .NET 2.0 code is not backward compatible with 1.1, so I would not
want to host different versions of the runtim,e in the same process. The
'solution' of using a new appdomain is also dodgy since all appdomains
share the same managed heap. Also threads in a managed process are free
to execute in any app domain - yes, the data is marshalled and the
context is applied, but the *same* thread is used. Threads in .NET
version 2.0 are different to version 1.1, so there is an
incompattibility there. Cowboy's suggestion is best - put the .NET code
into a separate process and access with some interprocess mechanism.
