Based on the answer here: Which, if any, recent Windows updates should I uninstall to revivify Silverlight or rectify other problems?, I uninstalled / reinstalled Silverlight and rebooted. Now, though, I get a compilation error, namely:
"The imported project "C:\Program Files (x86)\MSBuild\Microsoft\Silverlight\v5.0\Microsoft.Silverlight.CSharp.targets" was not found. Confirm that the path in the declaration is correct, and that the file exists on disk."
It points to this line in a *.csproj file:
<Import Project="$(MSBuildExtensionsPath32)\Microsoft\Silverlight\$(SilverlightVersion)\Microsoft.Silverlight.CSharp.targets" />
I don't understand what this is doing, exactly; if it's something grokkable from afar, what do I need to do to solve this dilemma?
UPDATE
When I try to install the Silverlight 4 Tools (as some indicate is a/the solution, such as at Silverlight 4: Resolving Microsoft.Silverlight.CSharp.targets was not found?), I get, "Installation Requirements:
Visual Studio 2010 or Visual Web Developer Express 2010 or Visual Phone Developer Express 2010 that matches the language version of Silverlight Tools 4 must be installed before installation of Silverlight Tools can continue. Silverlight Tools is available in other languages at http://go.microsoft.com/fwlink/?LinkId=177432. "
I do have VS 2010 (SP1) installed. And I even have VS Express (2012) for Web installed, too!
