While trying to debug a web service, I get the following error: "Could not load file or assembly 'PSCUWebService' or one of its dependencies. An attempt was made to load a program with an incorrect format". I'm using VS2012 on a 64-bit machine.
I checked the Configuration Manager and the projects have a mixture of platforms (x86, Any CPU, and one has x64). I changed them to all say 'Any CPU' and that didn't work.
I also checked the Platform target in the properties for the PSCUWebService project and all of its dependencies. The platform target for PSCUWebService was 'x64' and all of its dependencies had 'Any CPU'. I changed PSCUWebService to say 'Any CPU', rebuilt, and tried to execute only to receive a different error.
I'm not sure how to go about resolving this. Considering the research I've done, I'm pretty sure it has to do with the bitness of one of the assemblies. Any help would be appreciated.
Here's the assembly trace along with the stack trace just in case someone see's something I didn't see:

=== Pre-bind state information ===
LOG: DisplayName = PSCUWebService
(Partial)
WRN: Partial binding information was supplied for an assembly:
WRN: Assembly Name: PSCUWebService | Domain ID: 9
WRN: A partial bind occurs when only part of the assembly display name is provided.
WRN: This might result in the binder loading an incorrect assembly.
WRN: It is recommended to provide a fully specified textual identity for the assembly,
WRN: that consists of the simple name, version, culture, and public key token.
