Question

Maybe you can give a clue about this error, I have been googling and testing things for hours without result. I am using Mysql and Mysql connector 6.3.5. The error only happens on server, locally everything goes well.

The error:

Method not found:
‘System.Data.Objects.ObjectSet`1
MyModelEntities.get_my_aspnet_Users()’.

StackTrace:

[MissingMethodException: Method not
found:

A little bit more background info on your model would be needed to pinpoint the issue.

If I had to infer with only the stack trace… It seems that in your HomeController constructor there is a call to get_my_aspnet_Users on your model class – MyModelEntities. For some reason the code is not able to find that method.

Is it possible that you somehow have an older version of the model file that does not have the particular method your code is looking for?

Hope this helps.
