[Bug]: Cannot create a Project object with the long path prefix \\?\.

[MarkKharitonov]

Issue Description

Trying to create a Project object from a long path when using .NET Framework does not work - fails with various exceptions.

Steps to Reproduce

The following unit test passes, when it should fail on the first or second assertion:

    [Test]
    public void ProjectPath()
    {
        var path = ... ; // some project path 255 characters long
        Assert.That(() => new Project(path, new Dictionary<string, string>(), null), Throws.Exception);
        Assert.That(() => new Project(@"\\?\" + path, new Dictionary<string, string>(), null), Throws.Exception);
        path = ... ; // a shorter project path
        _ = new Project(path, new Dictionary<string, string>(), null);
    }

An important detail - the code must be targeting .NET Framework.

Expected Behavior

Using a long path should work. At least with the \\?\ prefix.

Actual Behavior

Either long path variant result in an exception. Albeit a different one.
