After updating Entity Framework model, Visual Studio does not see changes

If I do any changes to my EF 5.0 model, VS does not seem to see the changes. I have tried adding a new table, which shows up fine in the model, but then if I try to use it somewhere the table does not show up in intellisense and I can't use it.

I have also tried changing datatypes of a column, which again shows up fine if I look at the .edmx model file, but visual studio will still give me compiler errors on that field because I am trying to assign the incorrect datatype.

If I delete the EDMX completely, and recreate it, then the changes work fine. but it is tiresome to regenerate from database each time when I should be able to just "update model from database" and rebuild.

I have never had these problems with EF before. Does anyone know the cause or the fix to this problem?

Thanks.

First Build your Project and if it was successful, right click on the "model.tt" file and choose run custom tool. It will fix it.

Again Build your project and point to "model.context.tt" run custom tool. it will update DbSet lists.
