Question

Tuesday, March 14, 2017 1:39 AM

If I have 2 dlls with same name, public key token and culture.
How can I reference them both in the same C# project?

Scenarios: having to reference and old and new dll for the sake of upgrade.

Regards
Min Chew

Solution here

  1. In app.config
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
  <dependentAssembly>
        <assemblyIdentity name="myAssembly"
                          publicKeyToken="here token dll"
                          culture="neutral" />
       <bindingRedirect oldVersion="0.0.0.0-1.0.0.0" newVersion="1.0.0.0" />
       <bindingRedirect oldVersion="1.0.0.1-2.0.0.0" newVersion="2.0.0.0" />
       <codeBase version="1.0.0.0" href="folder\namedll.dll" />
       <codeBase version="2.0.0.0" href="folder\namedll.dll" />
    </dependentAssembly>
</assemblyBinding>
  1. Unload and edit the csproj file, and add or set:
<AutoGenerateBindingRedirect>false</<AutoGenerateBindingRedi‌​rect>

Using BindingRedirect can be tricky at best, you might consider asking here

This issue appears to a mix of C# (extern alias) and MSBuild as well as the csproj file, so probably is best in the Visual Studio General section.
