Today, I encountered an error/bug on my Visual Studio. Working with the MVC project I am doing, while trying to add a scaffolding controller. I can’t seem to find the ‘Add Controller’ in the context menu of Controller folder.
Sometimes a simple Clean all, Rebuild all works easily. Sometimes it’s just a bug on Visual Studio itself and a simple reboot of VS or reboot of your machine will work. But this time all of these steps won’t work.
Then I found out that the .cproj file was messed up and the ProjectTypeGuids is empty
<ProjectTypeGuids></ProjectTypeGuids>
I checked all the Guids equivalent of all the projects in my solution.
and this now works:
<ProjectTypeGuids>{E3E379DF-F4C6-4180-9B81-6769533ABE47};{349c5851-65df-11da-9384-00065b846f21};{fae04ec0-301f-11d3-bf4b-00c04f79efbc}</ProjectTypeGuids>
Here’s the link where I got my project types.
I will also lists here the ones that I usualy use:
