Hi,
I'm trying to develop a simple WCF service running in a 64 bit environment. I fire up VS2010 under Windows 7
New Solution -> WCF project -> Run -> It works fine.
As soon as I change the properties of the project in order to make it compile in 64 bit, running it throws the following exception:
Could not load file or assembly 'WcfService2' or one of its dependencies.
With the following Assembly Load Trace
=== Pre-bind state information ===
LOG: User = *****
LOG: DisplayName = WcfService2
(Partial)
WRN: Partial binding information was supplied for an assembly:
WRN: Assembly Name: WcfService2 | Domain ID: 4
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.
WRN: See whitepaper http://go.microsoft.com/fwlink/?LinkId=109270 for more information and common solutions to this issue.

LOG: Attempting download of new URL file:///d:/temp/WcfService2/WcfService2/bin/WcfService2.DLL.

How can I overcome the problem? Any idea? Thanks
EDIT:
The WCF does compile after setting the Platform Target to AnyCPU, but I need to specifically set a 64 bit compilation because I'm working with SharePoint objects and a AnyCPU (or x86) compilation results in the very same problem and error described here (and in other places on the net).
So either I compile AnyCPU/x86 and I get an error from the integration with SharePoint or I set the target platform to 64 bit and I get an error from WCF.
