.NET 4.0对错误的Oracle.DataAccess.dll的引用

Question

When I use my CruiseControl.NET Build Server to build my C# application it always references to the wrong Oracle.DataAccess.dll. On my local machine it is working without any problems.

My local machine and my build server are both Windows 7 machines. I installed the Oracle Client 11.2.0.3 (32 AND 64 bit) on both machines. My application is a .NET Framework 4.0 C# application. I set specific version and local copy of the OracleDataAccess.dll to false.

When I build it on my local machine everything works fine. I analyzed the file using IL-Disassembler, the reference here is ok:

.assembly extern Oracle.DataAccess
{
  .publickeytoken = (89 B4 83 F4 29 C4 73 42 )                         // ....).sB
  .ver 4:112:3:0
}

When I build it on the build server my application references to the wrong OracleDataAccess.dll. Here I get this reference:

.assembly extern Oracle.DataAccess
{
  .publickeytoken = (89 B4 83 F4 29 C4 73 42 )                         // ....).sB
  .ver 2:112:3:0
}

All the references in the project point to the 4... version. I reinstalled the 32 and 64 bit oracle clients. I checked all the oracle references on the build server, everything looks fine. After trying to find the error the whole day I don't know how to continue. Please, can someone help me with this problem?

In your *.csproj edit your reference to ODP.NET like this:

    <Reference Include="Oracle.DataAccess">
      <SpecificVersion>False</SpecificVersion>
      <Private>False</Private>
    </Reference>

Attributes like Version=... or processorArchitecture=... are not required. Your application will load the correct Oracle.DataAccess.dll depending on selected architecture and target .NET framework (provided that it is installed properly)
