When I finally got around to upgrading my Build tablet to run the Consumer Preview of both Windows 8 and VS 11 I immediately ran into an issue when trying to attach a ‘legacy’ VS11 project from the Developer Preview version to a new project using the Consumer preview.

The error I received can be seen below.

Turns out the problem is easy to solve.  Open up the offending csproj file and look for the line which looks like:

<Import Project="$(MSBuildExtensionsPath)\Microsoft\WindowsXaml\v1.0\Microsoft.Windows.UI.Xaml.CSharp.targets" />

Replace the line with

<Import Project="$(MSBuildExtensionsPath)\Microsoft\WindowsXaml\v$(VisualStudioVersion)\Microsoft.Windows.UI.Xaml.CSharp.targets" />

Once you replace the line you should be able to add the existing project as expected.

Till next time,
