When I use the Deploy To Azure button from this page:
https://github.com/Azure/azure-quickstart-templates/tree/master/201-web-app-github-deploy

Configure it to pull the content of my .NET 5 application at:
https://github.com/ADefWebserver/Blazor-Blogs.git

I get the following error:

    I can confirm that adding:
    "netFrameworkVersion": "v5.0"
    fixes the issue:

    Hi @Michael Washington ,

    I did hit the same error you did. I'm not certain what caused the build in deployment center to fail. It could be the fact this template creates a .NET47 runtime. I was, however, able to get around it by changing the runtime to .NETCore 5, disconnecting your git repo and re-add it in deployment center. I'll have to investigate why the template fails and update this post with my findings.

    Regards,
    Ryan
