作为依赖项和不同的publicKeyTokens共享时出现RestSharp错误

Question

Using APIs from Docusign , Twilio and Auth0 . All 3 have RestSharp.dll as a dependency.

If I use the RestSharp.dll included with the Docusign package, Docusign works well but Auth0 and Twillio give errors:

Could not load file or assembly 'RestSharp, Version=104.1.0.0, Culture=neutral, PublicKeyToken=null'

If I use the normal RestSharp.dll (Install-Package RestSharp), Twilio and Auth0 work fine but I get an error when using Docusign:

Could not load file or assembly 'RestSharp, Version=100.0.0.0, Culture=neutral, PublicKeyToken=5xxxxxxxxxxxx'

Adding binding redirects does not solve the issue. Without binding redirects, I get this error in the log:

Comparing the assembly name resulted in the mismatch: MAJOR VERSION.

If I do use a binding redirect:

Comparing the assembly name resulted in the mismatch: PUBLIC KEY TOKEN.

Binding redirect code:

<dependentAssembly>
    <assemblyIdentity name="RestSharp" culture="neutral" />
    <bindingRedirect oldVersion="0.0.0.0-105.2.3.0" newVersion="105.2.3.0" />
 </dependentAssembly>

Answer 1

Temporarily solved the issue by renaming the RestSharp.dll that was included with the Docusign package to "RestSharpDocusign.dll" and copied that into my project.

I modified the assembly bindings so that when version 100.0.0.0 was called it would load the special "RestSharpDocusign.dll" with the publicKeyToken Docusign wanted. Anything else would utilize the standard RestSharp.dll with a null publicKeyToken.

<dependentAssembly>
    <assemblyIdentity name="RestSharp" publicKeyToken="null" culture="neutral" />
    <bindingRedirect oldVersion="100.0.0.1-105.2.3.0" newVersion="105.2.3.0" />
</dependentAssembly>
<dependentAssembly>
    <assemblyIdentity name="RestSharp" publicKeyToken="598062e77f915f75" culture="neutral" />
    <codeBase version="100.0.0.0" href="ult/RestSharpDocusign.dll" />
</dependentAssembly>
