Hi all,
I am new to Rhinomock. We are using C++/CLI, and we want to add
Rhinomock to our unit test framework which builds in VS2008
professional version. The tested Rhinomock version is 3.6 which
supports C++/CLI. I created a C++/CLI unit test project of VS2008 as
following, it can be built successfully. But when run the test method,
it will throw an exception “..., System.InvalidOperationException:
Invalid call, the last call has been used or no call has been made
(make sure that you are calling a virtual (C#) / Overridable (VB)
method)..” I searched on the web, and found people says this exception
is usually for the tested function is non-virtual, but here it's a
virtual one. At the same time, I create a C# unit test project of
VS2008 with the similar code, and it could run successfully. I find it
will be failed in C++/CLI project if I use "LastCall::Return" or
"Expect::Call", throwing the same exception previous.

And my environment is XP with SP3, and VS2008 Professional with SP1.
So, my questions are:
(1) are there some errors in the above C++/CLI project? If have, how
to modify them, thanks.
(2) If it's the Rhinomock own bug, how to workaround it or when it
will be fixed. I saw Rhinomock has a commercial version. Does this
version has this problem too, or is it well to support C++/CLI than
the open source version？ Thanks.
(3) I find there are nearly no C++/CLI examples provided by Rhinomock,
does anyone can provided some. Thanks.
(4) For C++/CLI doesn't support lambda, some syntax and other mock
framework(like Typemock) can't be used. Is there other mock framework
well to support C++/CLI? Thanks.
