Microsoft.Silverlight.CSharp.targets

报错：

Unable to read the project file 'XNTVOD.AdminClient.csproj'. C:\Path\To\MyProject.csproj(593,3): The imported project "C:\Program Files (x86)\MSBuild\Microsoft\Silverlight\v4.0\Microsoft.Silverlight.CSharp.targets" was not found. Confirm that the path in the <Import> declaration is correct, and that the file exists on disk. 

 

解决： 

The file that's missing ships in the Silverlight 4 SDK. You can either install just the Silverlight 4 SDK, or re-install the entire Silverlight 4 Tools for VS2010 package (which will re-install the developer runtime, SDK, a hotfix for VS2010, the Silverlight 4 Tools package, and WCF RIA Services).
