Solution Parser not working in .Net8

Question

Hi,

I'm in the process of migrating my WPF application from .NET Framework 4.8 to .NET 8. In my previous application, I utilized the Solution Parser functionality from Microsoft.Build for certain tasks. However, after migrating to .NET 8, this functionality seems to be failing. To illustrate the issue, I've created a sample solution. I would appreciate it if you could take a look and help me identify the cause of the failure in .NET 8.

Thanks,

I examined the project a little. I want to share a few things that caught my eye,

1. Correct API Usage: The MSBuild API has changed, and directly loading a solution file using ProjectCollection.GlobalProjectCollection.LoadProject might not work. You should use the SolutionFile class from Microsoft.Build.Construction to parse the solution file.
2. Check Compatibility: Ensure the versions of Microsoft.Build and Microsoft.Build.Locator are compatible with .NET 8.

Replace the ParseSolution method in MainWindow.xaml.cs with the following:

using Microsoft.Build.Construction;
private void ParseSolution()
{
    string solutionPath = @"path\to\your\solution.sln";
    var solution = SolutionFile.Parse(solutionPath);
    foreach (var project in solution.ProjectsInOrder)
    {
        OutputTextBox.Text += project.AbsolutePath + "\n";
    }
}

This should correctly parse the solution file and list the projects within it.

Make these changes and see if the issue is resolved.
