Issue:

You have an ASP.NET Core project that you are trying to publish to an Azure Container registry with dotnet publish. You are getting this error:

C:\src\path-to-project\Project.Api.csproj : error : The attribute "Include" in element <ContainerEnvironmentVariable> is unrecognized.
.
Resolution:
The container environment variable node allows you to add environment variables to the container. Environment variables are accessible to the app running in the container immediately, and are often used to change the run-time behavior of the running app.

The ContainerEnvironmentVariable node has two attributes:

• Include: The name of the environment variable.
• Value: The value of the environment variable.

<ItemGroup>
  <ContainerEnvironmentVariable Include="LOGGER_VERBOSITY" Value="Trace" />
</ItemGroup>

So it should be an ItemGroup and not a PropertyGroup. More info here.
