I experienced the similar error, and my issue was that I had Entities with the same name in two separate edmx models. I suppose EF was sending a message because some of the associated entities couldn't be loaded....I found the solution by deleting entities from one model (I suppose changing the name might also work) and reconstructing the solution....
The columns in our database table are as follows....WidgetId (PK)...WidgetName ...WidgetCreatedOn ...WidgetLastUpdatedOn...The update, delete, and insert operations on the Widget table are handled by stored procedures....The WidgetName is passed as a parameter to the Insert stored procedure, for example.... exec Widget_Insert @WidgetName='Foo Widg...
By choosing "Update model in database" from the context menu when I right-click on the.edmx file, I'm attempting to update the model. But the contextual menu does not have this option; am I missing something?
