Can't compile project - VB.Net - Fatal error BC2000 - Xamarin/MonoDevelop

Hey All,

Just downloaded Xamarin/MonoDevelop in order to create a VB.Net based cross-platform application.

However Xamarin keeps returning a fatal error when attempting to compile a default template.

Steps:

  1. File > New > Solution

  2. VBNet > Gtk# 2.0 Project

  3. Name solution

  4. Click Play (Debug)

Results:

Error Fatal error BC2000 : compiler initialization failed unexpectedly: Project already has a reference to assembly System. A second reference to 'C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework.NETFramework\v4.0\System.dll' cannot be added. (Fatal error BC2000 ) (test111)


The above occurs if I click Play, Build, Run/Start Without Debugging, and Run/Start With Debugging.

There is only one reference to System within the References folder in the Solution tree.

Any help would be greatly appreciated!

Thanks.

    The above does not occur with a C# Gtk# 2.0 project.

    VB.NET is not supported

  • MirageMirage USMember

    Then why is the option there in New > Solution?

    VB.NET support is part of the open-source MonoDevelop project that Xamarin Studio is based on, but it's not a feature that's officially supported by Xamarin. It will probably be moved out to an optional add-in, which will be installable via the Add-in Manager.

    However, please file a bug to track this issue.
