BadImageFormatException when trying to reference K2 API.

Hello,


When IIS in Windows 2008 x64 tries to start up and is running through the assemblies it dies with:


Message: Could not load file or assembly 'SourceCode.Workflow.Client' or one of its dependencies. An attempt was made to load a program with an incorrect format. (C:WindowsMicrosoft.NETFramework64v2.0.50727Configweb.config line 59)


Typically a BadImageFormatException has to do with an x86 vs x64 mismatch.  Our assemblies are built with Any CPU. 


Are there any x86 or x64 restrictions on the K2 assemblies?

The K2 client assemblies are x86 or x64 specific.  Normally, this error happens when you copy x64 dlls to a x86 web application or vice versa.


To fix this, you need to get a copy of the correct assemblies from the appropriate platform.  I guess it's a lot easier to keep the web and K2 server on the same platform type.  This tends to reduce issues like this.
