I believe this is caused by any .net ca being done in a separate stub process.
Prior to .net 4, you could only have one version of the clr loaded during the
life of the process. The wix fix which allows us to overcome this is using
child stub processes and ipc to overcome this.

Hi, WIX Devs
Thanks for such a great tool!
I have a problem developing my own installers with Wix.
I defined several custom actions in a DLL, these functions share a same
behavior that they need to send the instrumentation data to our server through
HTTP request.
When WIX calls a custom action, as my observation, it starts a new thread for
the function, and the thread exits after the function is returned.
However, the problem is when the thread exits, the heap storage created in the
custom action thread is also removed! Which leads to a crash when HTTP callback
thread tries to access the objects created in the heap.
What described above is only my observation, I just want to confirm whether
this is really the memory management method of thread adopted by WIX (something
like ThreadLocal, if I understand correctly), therefore we can think about
other ways for solution.
Thanks,
Yun
