After clicking the “Generate Solution” button for the Cloud Code C# Reference (.ccmr), I immediately clicked the “Generate Bindings” button next to it. An error occurs at this point.

I downgraded the .NET SDK version.

dotnet --version
9.0.317

async Task<string> GetVersionString(CancellationToken cancellationToken)
{
    return "--fx-version 9.0.19";
    #if !CLOUD_CODE_AUTHORING_DISABLE_VERSION_DETECT
    var versions = await m_DotnetRunner.GetAvailableCoreRuntimes(cancellationToken);
    var last = versions.LastOrDefault(v => v != null);
    string versionSelect = string.Empty;
    if (last == null)
        m_Logger.LogWarning("Failed to identify latest available SDK");
    else
        versionSelect = $"--fx-version {last}";
    return versionSelect;
    #else
    return string.Empty;
    #endif
}

and also tried hardcoding the GetVersionString() function to return --fx-version 9.0.19, but I still get the following error:

Patching Microsoft.Extensions.Logging.Abstractions.dll from v8.0.0.0 to v9.0.0.0 reveals a second, identical error for a different assembly

If by downgrade you mean you uninstalled version 10 you might have broken something else. It’s meant to be installed alongside any existing .NET version.

Since it’s missing a .NET functionality I’d recommend a repair install of Visual Studio and make sure it has both the .NET 10 and 9 SDK versions checked.

If you run 3rd party antivirus: disable or uninstall (Defender is just as capable).

More precisely, I configured the Unity project’s global.json to use the 9.x SDK.

{
  "sdk": {
    "version": "9.0.317",
    "rollForward": "latestPatch"
  }
}

These are the individual components currently installed in Visual Studio. What else do I need to add?

Additional information I discovered.

Hi @NewPattern,

Thanks for raising this. Similarly to your other post, we believe this is a bug in the exp8 version of the package.

For what it’s worth, I also think the two issues are related, and down to the versions of the bundled DLLs for the Bindings Generator that happened to be released in exp8.

I would recommend you switch to 3.0.0-exp.9 (see here). Please let us know if this addresses the issue, otherwise we can investigate further.

Thanks again!
