Association end is not mapped in ADO entity framework

Question

I am just starting out with ADO.net Entity Framework I have mapped two tables together and receive the following error:

Error   1   Error 11010: Association End          


        

Answer 1

There's not a lot of information in your question, but, generally speaking, this means that there is an incompletely defined association. It could be that you have tried to map one table with a foreign key to another table, but have not mapped that other table. You can also get this error when you try to do table per type inheritance without carefully following the steps for implementing that feature.
