Resolving .NET assembly reference to a different name?

Question

My project references Library1.dll and Library2.dll. Library2.dll has a dependency on Library1.dll, but it was compiled to reference it by a different name, Library1.Net40.dll.

Is there an nice way tell my application to redirect all references for Library1.Net40.dll to resolve to Library1.dll? Maybe something similar to the way you can redirect versions using a <bindingRedirect>?

I've got a solution that handles the AppDomain.AssemblyResolve event, but it's a bit of a hack and am hoping there's a better way to do this.

Edit: For anyone's reference, here's how I ended up solving it using the AppDomain.AssemblyResolve event to redirect to a different assembly.

Answer 1

Have you tried playing with the <codeBase> element?

<configuration>
   <runtime>
      <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
         <dependentAssembly>
            <assemblyIdentity name="Library1.Net40"
                              publicKeyToken="..."
                              culture="neutral" />
            <codeBase version="2.0.0.0"
                      href="Library1.dll"/>
         </dependentAssembly>
      </assemblyBinding>
   </runtime>
</configuration>

(Untested; no idea if it works.)

Good idea, thanks. I got the redirect working but it complains because the names are different, here's the log:
