Visual Studio Publish Error "GenerateEnvTransform" task failed unexpectedly

I am trying to publish a new Blazor Server project (with docker support) to Azure App Service Container using Visual Studio 2019. It builds and runs just fine locally. When I go to publish, I receive the error:

The "GenerateEnvTransform" task failed unexpectedly.
System.IO.DirectoryNotFoundException: Could not find a part of the path '[PathToProject]\obj\Debug\netcoreapp3.1\PubTmp\EnvironmentWithLocation.transform'.

I have also tried with different framework versions, including .Net 5. I have also tried changing the configuration from dev to release. This is just a bare-bones project trying to setup, I didn't touch any of the default template code files. I am using Windows 10 with the Docker Windows App running.

Update your docker and vs2019 to the latest version.

I'm not sure why you get this error. According to your description, create and publish the application, I did not encounter the same error as you, so I suggest you try again after updating.

Tips

Make sure that the version of your app service is consistent with the version of the project, for example, both are .net 5.
