ClassFactory cannot supply requested class

[BrentHoskisson]

I loaded my SOE (which works great on 10.0) into 10.1.  Added it to the capabilities of my service and attempted to start it up.

I get:

Failed to construct instance of service '<service name>.MapServer'. ClassFactory cannot supply requested class

from the Server.

What does this mean?  How do I fix it?

I have verbose logging on and am getting nothing from my SOE (which logs fine in 10.0).

Thanks,

Well this tipped me off - even if my solution wasn't any of theirs.  I had been compiling my soe in x86 mode.  When I compiled as "Any CPU" it worked ok.

I'll post this over there, too, for any one else who is searching for solutions to this problem.

Thanks
