Old RestSharp version in Revit 2025

[SwainStrain]

Hello, 

I am trying to load a specific version of the RestSharp library into Revit 2025, specifically version 106.15.0.0. However, when I run Revit 2025, I notice that a newer version, 108.0.1.0, is being loaded from the Lightbox plugin.

I tried adding a binding redirect to the app.config file to force the loading of the older version, but nothing changed.

Is it possible to force the loadin of the older version? Thank you

Yes. Luckily for you, starting in Revit 2025, this is possible, cf.:

I just tried out the SDK, when I saw that it is using a version of RestSharp that is compromised I tried installing a version that isn't before delivering code.  I have things compiling with the web.config and project updates:

<configuration>
  <runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <dependentAssembly>
        <assemblyIdentity name="RestSharp" publicKeyToken="598062e77f915f75" culture="neutral" />
        <bindingRedirect oldVersion="0.0.0.0-112.0.0" newVersion="106.15.0" />
      </dependentAssembly>
    </assemblyBinding>
  </runtime>
</configuration>

And 

<PackageReference Include="RestSharp" Version="106.15.0" />

But, "Could not load file or assembly 'RestSharp, Version=108.0.1.0, Culture=neutral, PublicKeyToken=598062e77f915f75'. The system cannot find the file specified."

If only it was as easy as uninstalling everything forge/RestSharp related, deleting obj/bin/.vs files, recompiling and reinstalling.

Are there plans to update the SDK to stop using RestSharp or at least the constructor they have deleted in the newer version?
