Get Web Essentials to work with TypeScript in Visual Studio 2013
When you install the Web Essentials plugin to your Visual Studio 2013 installation it is very probable that the next time you open a TypeScript project in Visual Studio the program will freeze and you cannot do any further action inside Visual Studio.
If that is the case, then the following will do the trick and let you again start your projects.
Go to the root folder of the solution that contains your TypeScript projects and from your file explorer activate the option to see the hidden files inside this folder. Then spot the .v11.suo file and delete it (no panic, the file is going to be regenerated the next time you start the solution from Visual Studio).
That’s it.
