Can't add .NET 4.0 Assembly Reference In MonoDevelop 2.4.1

I've installed MonoDevelop 2.4.1 With Mono 2.8.1. My trouble is that i can't add assembly reference to assembly compiled for .NET 4.0 (on sa开发者_JS百科me MonoDevelop IDE).

What am i do. References -> Edit References -> .NET Assembly -> Browse to file & select it

Than MD displays an error that an assembly that i'm trying to add isn't .NET assembly. I've set profile to .NET 4.0 everywhere.

Reflector disassembles my assembly fine so it's ok. My OS is Windows 7 What's wrong?

UPD: Posted a bug to Novell. Here it is https://bugzilla.novell.com/show_bug.cgi?id=659894

When i do "C:\Program Files\Mono-2.8.1\bin\mono.exe" "C:\Program Files\MonoDevelop\bin\MonoDevelop.exe" the problem disapears.

It's understood that by running MonoDevelop.exe it runs on Microsoft .NET and the issue is that MonoDevelop (.NET 2.0 assembly) can't recognize an assembly (.NET 4.0) with use of 2.0 APIs.

Lets look at code (MonoDevelop.Ide.Projects.AssemblyReferencePanel):

private void SelectReferenceDialog(object sender, EventArgs e)
{
    string[] array = new string[this.chooser.Filenames.Length];
    this.chooser.Filenames.CopyTo(array, 0);
    foreach (string str in array)
    {
        bool flag = true;
        try
        {
            AssemblyName.GetAssemblyName(Path.GetFullPath(str));
        }
        catch
        {
            flag = false;
        }
        if (flag)
        {
            this.selectDialog.AddReference(new ProjectReference(ReferenceType.Assembly, str));
        }
        else
        {
            MessageService.ShowError(GettextCatalog.GetString("File '{0}' is not a valid .Net Assembly", str));
        }
    }
}

The line AssemblyName.GetAssemblyName(Path.GetFullPath(str)); is a source of all evil. I'm going to post a bug report to novell. Or it's not a bug?
