+## Why are the project names in my solution file the file name of the project without the extension?
+This is the default behavior of Visual Studio to use the file name without the extension for the name of a project in the solution.  You can change this behavior by setting the `SlnGenProjectName` property:

 ## How do I troubleshoot SlnGen?
 You can generate a diagnostic log by specifying the `--binarylogger` command-line parameter:
