I am building a REST WCF Application in top of Windows Azure. In localhost I am able to connect and use SQL Azure with NHibernate nicely, but whenever I try to move the application to Windows Azure, it cannot load the required DLLs for NHibernate to work properly.
I’ve seen forums where it says that this problem might occur if the NHibernate DLLs were compiled with x86 target, and since Windows Azure runs on x64, I tried to modify the target of my build to x64 (although I am running Windows 7 x86).
The problem it is displaying is
The server encountered an error
processing the request. The exception
message is ‘Unable to load type
‘NHibernate.ByteCode.Castle.ProxyFactoryFactory,
NHibernate.ByteCode.Castle’ during
configuration of proxy factory class.
Possible causes are: – The
NHibernate.Bytecode provider assembly
was not deployed. – The typeName used
to initialize the
‘proxyfactory.factory_class’ property
of the session-factory section is not
well formed. Solution: Confirm that
your deployment folder contains one of
the following assemblies:
NHibernate.ByteCode.LinFu.dll
NHibernate.ByteCode.Castle.dll’. See
server logs for more details.
Have anyone has seen this error before? How do I solve this?
Well, it turned out that this didn’t had anything to do with Azure, which runs it fairly effortless.
To make this to work I had to hack the msbuild process, who was “smart” enough to leave out the Castle dll. As stated, this should not be a permanent fix, because you will need to modify msbuild configuration so it includes the required dll’s. I just don’t know how to do that yet, perhaps the geniuses at StackOverflow can help us.
