Silverlight 4: Resolving Microsoft.Silverlight.CSharp.targets was not found?

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:

  1. Microsoft Silverlight
  2. Microsoft Silverlight 3 SDK
  3. 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 I don't want to install stuff that will get me right back to the situation I had before this one with outdated components.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...
