[Problem/Bug]: NuGet package Microsoft.Web.WebView2 build files do not work in some MsBuild scenarios

What happened?

Building a CSPROJ with MSBuild does not work when the targets restore and Build are called in the same MSBuild run.

The error was introduced with the new non-standard NuGet structure.

Repro steps

Create a sample project:

dotnet new classlib -f net8.0 -o WebView2Test
cd .\WebView2Test\
dotnet add package Microsoft.Web.WebView2

Add a Test.cs file:

namespace WebView2Test;

using Microsoft.Web.WebView2.Core;

public class Test
{
    public static async Task Initialize()
    {
        await CoreWebView2Environment.CreateAsync();
    }
}

Build using this command:

msbuild /T:"restore;Build" .\WebView2Test.csproj

Result (sorry, machine has German culture):

error CS0234: Der Typ- oder Namespacename "Web" ist im Namespace "Microsoft" nicht vorhanden. (Möglicherweise fehlt ein Assemblyverweis.)
