I have a strange error with Visual Studio 2010 in that Entity Framework doesn’t work for me.
In the toolbox down the side the icon for the EntityDataSource (and several other components) shows a text snippet icon:
Then when I try to insert it via double clicking I just get a massive bunch of text inserted instead of the control:
I have tried installing the latest Entity Framework 4.1 standalone installer. I have also installed the Visual Studio 2010 SP1. I did have the SP1 RC installed before but the install notes for SP1 state clearly that you don’t need to uninstall the RC before installing the final SP1.
I have been using Linq to SQL for a long time now and finally wanted to start learning EF so I am not sure how long this has been broken and I just haven’t noticed.
It seems that the issue has occurred for others:
But Microsoft closed the bug as not-reproducible. I commented on there about a month ago but nothing has been responded to.
As I stated in that thread I did try the fix suggested but it didn’t work.
Does anybody have any idea what steps I can take to get this working?
It seems that the most obvious solution doesn’t occur until after you have spent 10 minutes taking screenshots and posting up a question on SO.
I have just solved this issue by right clicking on the toolbox and choose Reset Toolbox.
