Sharepoint 2013 - showing Task Due Date in Content Query Web Part (CQWP)

To get the Due Date of a task to appear in a content query web part you need to configure the web part to use 'TaskDueDate', not 'DueDate'.  This then resolves in the web part to Due Date [Core Task and Issue Columns].

Visual Studio stuck on "Waiting for parse to complete..."

Today when I opened my sharepoint 2013 solution in Visual Studio 2013 it got stuck loading a project with the message in the status bar of "Waiting for parse to complete...".  Yesterday before I closed visual studio I was looking at a large xsl file which I had left open before closing visual studio.  I think this may have been the file it was stuck on?

The way I fixed it was to remove the mapping in Visual Studio to the solution and re-add it in Source Control Explorer.  To remove mapping:

1. Backup your source code to another folder
2. go to Source Control Explorer
3. right click on the folder that contains the solution
4. Go to Advanced > Remove Mapping...
