ODP.NET

I have migrated my .Net solution from 3.5 to 4.0 which consist of a class library and a web service. Web serivice is dependent on class library and the class library uses oracle.dataaccess.dll version 4.112.3.0. I have installed ODAC 11.2.0 in my machine.

When I try to build the solution using MSBUILD.EXE I am getting the below error on my build machine.

ASPNETCOMPILER : error ASPCONFIG: Could not load file or assembly 'Oracle.DataAccess' or one of its dependencies. An attempt was made to load a program with an incorrect format. [D:\VEROS_BuildFolder\CDDS_MERGE_CODEDROP_.NETUPGRADE\WEB Services\AppraisalSubmission\AppraisalSubmissionService.metaproj]

And I try to build from VS2010, it is building successfully.

But we need to build only using MSBUILD.EXE which resides in "C:\Windows\Microsoft.NET\Framework\v4.0.30319" path. While building using MSBUILd.EXE the Oracle.DataAccess.dll is getting copied into the BIN folder of the web service. It should reference from GAC location. My build serveer is 64 bit win2008 server. when I checked the dll version install using GACUTIL , I got the below result

C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\bin\NETFX 4.0 Tools>gacutil /l oracle.dataaccess

Previous the application was building successfully using framework 3.5 and Oracle.DataAccess.dll version 2.112.3.0.

Please help to build my applicaiton using MSBUILD 4.0 version.
