Solutions should work on VS2008
Steps required to implement this:
- Clone your solution file, typically ending it with "VS2008.sln" to make it explicit that this is the "beta" solution file.
- Open in VS2008, and complete the upgrade wizard. This will remove from the project files the MSBuild import of WPF targets, as they are built-in VS2008.
- Close the solution, and open each project file with a text/XML editor. Towards the end of the file, add the following Import:
<Import Project="$(MSBuildBinPath)\Microsoft.CSharp.targets" />
<Import Project="$(MSBuildBinPath)\Microsoft.WinFX.targets" />
