global.asax run-time compilation issue... (sometimes)

Some background:

Currently, we copy the IdeaBlade assemblies for the current version of DevForce that we have installed (6.0.4) to a ReferenceAssemblies directory in our source repository, and reference those assemblies via the "Browse" tab in the "Add Reference..." dialog.  Now, I'm fully aware that it's a better practice to reference assemblies directly in the ".NET" tab of the "Add Reference..." dialog, and while that may fix the problem we're seeing it's not an ideal solution for us.  The reason we copy/browse is because not all our developers have DevForce installed, and when we branch our code, we prefer to have the exact 3rd party assemblies in the source control branch to avoid having to determine what version of 3rd party suites to install when performing maintenance on a previous version of our application (also helps during application deployment). 

 

That all said we're seeing some oddness that's been tricky to track down.  Some of our developers get the run-time compilation error below, others do not.  Basically there's 3 different scenarios. 

 

1) Developer that does not have any version of DevForce installed and application runs successfully.
2) Developer that has DevForce 6.0.4 installed and application runs successfully.

3) Developer that has DevForce 6.0.4 installed and application fails to run successfully due to the run-time error.

 

#3 is the crazy one.  Developer 1 and 2 prove that things are set up 'right', but for whatever reason, Developer 3 is unable to run the application.  To add to the weirdness, if Developer 3 uninstalls DevForce, everything runs ok!  If Developer 3 then reinstalls DevForce 6.0.4, things no longer work again.

 

Anyone have any ideas?

 

 

If it helps any, our Reference Properties:

 

 

And the XML in the .csproj file:

 

    <Reference Include="IdeaBlade.EntityModel, Version=6.0.4.0, Culture=neutral, PublicKeyToken=287b5094865421c0, processorArchitecture=MSIL">
      <SpecificVersion>False</SpecificVersion>
      <HintPath>..\Reference Assemblies\IdeaBlade\EFAssemblies\IdeaBlade.EntityModel.dll</HintPath>
    </Reference>

That screenshot came from the Dev 3 scenario, with DevForce installed.  The really odd part is when Dev 3 uninstalls DevForce, the properties for that assembly reference automatically switches to Copy Local = true.  Reinstalled, it switches back to Copy Local = false.  Once I explicitly set Copy Local = true, Copy Local remains true forever.

 

Thanks!
