I'm getting an error about not being able to find Microsoft.XXX.targets. How do I fix this?

Possibility 1: Could be related to the .TARGETS file rename

For the Beta 1 release, all of the ""MSBuild"" .TARGETS files were renamed to follow our recommended naming convention. The renames are as follows:

Old name (pre-Beta1)	New name (Beta 1 and beyond)
""CSharp.targets""	""Microsoft.CSharp.targets""
""VisualBasic.targets""	""Microsoft.VisualBasic.targets""
""VisualJSharp.targets""	""Microsoft.VisualJSharp.targets""
""Framework.targets""	""Microsoft.Common.targets""

So ... if you are using a VS project file that was created using Beta 1 bits, but are trying to load that using a "Pre-Beta 1" drop, then you might get this error. If you must do this, you could try editing the project file on the line that says:

<Import Project="$(MSBuildBinPath)\Microsoft.XXX.targets" />

and change it to use the old name. But that still may not be guaranteed to work because there have been other breaking changes in the project file format.
