I’ve been upgrading some Silverlight 3 apps to Silverlight 4 in Visual Studio 2010. My Silverlight 3 apps open fine in Visual Studio, but SL4 apps don’t, with the following error:
C:\Path\To\MyProject.csproj : error : 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.
I had a problem with older VS Silverlight components and recently uninstalled most of the SL components, and right now in Add/Remove programs I have:
- Microsoft Silverlight
- Microsoft Silverlight 3 SDK
- Microsoft Silverlight 4 Toolkit April 2010
The <import> declaration looks like this for the SL4 project:
<Import Project="$(MSBuildExtensionsPath32)\Microsoft\Silverlight\$(SilverlightVersion)\Microsoft.Silverlight.CSharp.targets" />
That folder, C:\Program Files (x86)\MSBuild\Microsoft\Silverlight\v4.0 only has two files in it:
Microsoft.Ria.Client.targets
Microsoft.Ria.Client.VisualStudio.targets
What Silverlight development component am I missing in particular? I see a bunch of different options, from Silverlight 4 SDK Beta to VS Tools for Silverlight 4 and a bunch of others. I don’t want to install stuff that will get me right back to the situation I had before this one with outdated components.
Looks like this is the missing piece…
