Description Avenger 2016-01-30 23:08:18 UTC
Hello, this is a pretty straightforward bug that I think you may fix it in a tad.

On .NET 4.0, at least, we can use the following program:
[code]
var projectFile = "../../ListCompileFiles.csproj";
var projectInfo = new Project(projectFile);
Console.WriteLine("'Compile' items list: ");
foreach (var item in projectInfo.Items)
{
    if (item.ItemType == "Compile")
    {
        Console.WriteLine("Compile item: " + item.EvaluatedInclude);
    }
}

Console.WriteLine("Listing complete. Total " + projectInfo.Items.Count() + " entries.");
[/code]

On Mono though, it will not work, showing always 0 projectInfo.Items.

If we change line 2 to:
var projectInfo = new Project(XmlReader.Create(projectFile));

Then the code works just fine on both platforms!

Conclusion:
https://github.com/mono/mono/blob/master/mcs/class/Microsoft.Build/Microsoft.Build.Evaluation/Project.cs#L157

Should use XmlReader.Create() instead of ProjectRootElement.Create() (which it uses with the result of XmlReader.Create()!.
