I am getting a messge that says license not found.  We periodicaly get this error when a file named "license" appears in the properties folder of the solution.  We usually just delete the file and error goes away.  This time I'm getting the error and there is no license file.  Its a problem because the xaml editor in visual studio has wavy lines under every line of xaml and its not easy to read. The project builds and runs just fine.
