[Mono-dev] System.ExecutionEngineException: Failed to create shadow copy (CopyFile).

[Alistair Bush]

I have be working to get the fubu (mvc) framework and associated tools
working on mono/linux.
I have gotten most of the way to running a basic app but have sadly come
stuck on the following and am running out of ideas.

Basically I have setup a 'web' project using fubu new and am attempting to
run it by calling fubu run.

Sadly i'm getting the output [1] and as you will be able to see this is
caused by a ExecutionEngineException when attempting to call
Type.IsAssignableFrom.

At this particular point in the code it is my understanding that the
application is within a separate app domain ( see
Bottles.Services.Remote.RemoteServicesProxy ).

This is anything which should be stopping mono from inspecting Type
information on a Type when within a separate app domain?

Also it the moment im a little stuck on how to get more information to
debug this issue.  Any suggestions would be welcomed.   Thanks.
