Error building ComVisible library in TFS Build Server

Question

I have a solution with 24 projects that we have been building in TFS Build Server successfully for quite a while.  We just added a new project to the solution that builds a ComVisible dll containing a ComVisible class called UploadParams.  Now when we build on build server, I get the following error:

C:\WINNT\Microsoft.NET\Framework\v3.5\Microsoft.Common.targets(3019,9): error MSB3216:
 Cannot register assembly "f:\tfsbuild\Comm\STARs10Server\Binaries\Release\STAR.Common.Upload.dll" - access denied. 
Please make sure you're running the application as administrator. 
Access to the registry key 'HKEY_CLASSES_ROOT\STAR.Common.Upload.UploadParams' is denied.

I need to build this dll as part of the team build but I don't need to register the dll on the build server.  How can I make it build as ComVisible while preventing the attempt to register the COM library?

Regards,

Dale

Hi Dale,

The Task in "C:\WINNT\Microsoft.NET\Framework\v3.5\Microsoft.Common.targets(3019,9)" is

<Target
        Name="UnmanagedRegistration"
        Condition="'$(RegisterForComInterop)'=='true' and '$(OutputType)'=='library'"
        DependsOnTargets="$(UnmanagedRegistrationDependsOn)"
        >

        <RegisterAssembly
            Assemblies="@(_OutputPathItem->'%(FullPath)$(TargetFileName)')"
            TypeLibFiles="@(_OutputPathItem->'%(FullPath)$(TargetName).tlb')"
            AssemblyListFile="@(_UnmanagedRegistrationCache)"
            CreateCodeBase="true"
            Condition="!Exists('@(_UnmanagedRegistrationCache)')"/>

        <ItemGroup>
            <FileWrites Include="@(_OutputPathItem->'%(FullPath)$(TargetName).tlb')"/>
        </ItemGroup>
    </Target>

It seems that you checked  RegisterForComInterop in Build Tab of Project Property Page. You can uncheck it for the Configuration and Platform used in Team Build.

Thank you, Ruiz.  It seems so obvious now.  That fixed it.
