You need to mapcreatedassociation to the table of the many side in order to finish the process. Click on the association and in the Table Mapping View map the association to the table of the many side - Persons. After doing so you'll need to map the relevant keys on both sides. In a old post I wrote about how to add many to many relationship I showed an example how to do such a thing in Step 3 – Adding Many to Many Association in the Designer.

This is puzzling to me https://social.msdn.microsoft.com/Forums/en-US/dc506361-10e5-4bf6-8b98-b1d4d60a85b0/how-to-create-association-betwwen-two-entities-in-edm-designer-?forum=adodotnetentityframework because the error seems to be eminating from the fields within the same table. How can this be? What is the remedy for this? Thanks!

To resolve this error, map the property to the data source. For more information, see How to: Map Entities to Database Tables (Entity Data Model Tools). Regards, Gopalan Mani My Tech blog Reply bja58 None 0 Points 9 Posts Re: Error 11009: Property 'xxx' is not mapped Aug 30, 2011 01:32 PM|bja58|LINK thanks. I'll give it a try. One thing I don't understand, however, is why these properties were created to begin with. Is that function of the "conceptual" model you speak of? or is it a function of other associations I created? For example: If I have three tables (Client, Job and Specialty) and each one is associated to the one next to it. why would Job table end up with properties that are not mapped? Thanks again.

I was getting confused between "Association" and "Mapping". thanks again.

I created the entities and associations in the Model Viewer and then ask it to generate the database from the model. Immediately I get is not mapped a selection of validation errors and a pop-up informs me that I must clear all validation errors before I can generate the database. The errors in question are all along the lines of: Error 11007: Entity type 'EntityName' is not mapped. Or Error 11008: Association 'AssociationName' is not mapped. I get this error once for each new Entity and Association I have created. Now I get that they are not mapped to the database yet, this seems quite logical as they are totally new to the model. That is why I'm trying to use the "Generate Database From Model" tools to generate the database. Am I understanding correctly that I cannot generate a new database from the model because the new Entities and Associations I have added to the Model are not already in the database? If so, how do I work around this? visual-studio-2010 entity-framework poco share|improve this question asked Dec 29 '11 at 16:53 glenatron 7,45374686 2 If all that's wrong is unmapped associations and entities, "generate database from model" should work, and I've used it that way myself.
