C# - Entity Framework - An unhandled exception of type 'System.StackOverflowException' occurred in mscorlib.dll

Question

An unhandled exception of type 'System.StackOverflowException' occurred in mscorlib.dll
Make sure you do not have an infinite loop or infinite recursion.

The below code is called on a success of this method:

internal static List<RivWorks.Model.Negotiation.ProductsSold> GetProductsSoldByCompany(Guid CompanyID) {     var ret = from a in _dbRiv.ProductsSold where a.Company.CompanyId == CompanyID select a;     return ret.ToList(); } 

On the return it calls into the Entity Model and tries to populate all foreign keyed objects (child objects). The schema is [1 Company has 0 to many ProductsSold]. For some reason, the call into the following code just cascades on itself:

[global::System.Data.Objects.DataClasses.EdmRelationshipNavigationPropertyAttribute("RIV_Model", "FK_ProductsSold_Company", "Company")] [global::System.Xml.Serialization.XmlIgnoreAttribute()] [global::System.Xml.Serialization.SoapIgnoreAttribute()] [global::System.Runtime.Serialization.DataMemberAttribute()] public Company Company {     get     {         return ((global::System.Data.Objects.DataClasses.IEntityWithRelationships)(this)).RelationshipManager.GetRelatedReference<Company>("RIV_Model.FK_ProductsSold_Company", "Company").Value;     }     set     {         ((global::System.Data.Objects.DataClasses.IEntityWithRelationships)(this)).RelationshipManager.GetRelatedReference<Company>("RIV_Model.FK_ProductsSold_Company", "Company").Value = value;     } } /// <summary> /// There are no comments for Company in the schema. /// </summary> [global::System.ComponentModel.BrowsableAttribute(false)] [global::System.Runtime.Serialization.DataMemberAttribute()] public global::System.Data.Objects.DataClasses.EntityReference<Company> CompanyReference {     get     {         return ((global::System.Data.Objects.DataClasses.IEntityWithRelationships)(this)).RelationshipManager.GetRelatedReference<Company>("RIV_Model.FK_ProductsSold_Company", "Company");     }     set     {         if ((value != null))         {             ((global::System.Data.Objects.DataClasses.IEntityWithRelationships)(this)).RelationshipManager.InitializeRelatedReference<Company>("RIV_Model.FK_ProductsSold_Company", "Company", value);         }     } } 

As you can see, the first method makes a call to the second method. The second method seems to call itself endlessly.

How do I fix this in EF?

Answer 1

After 3 times at deleting and rebuilding my model from scratch, the stack overflow is magically gone. <grrrrr />

Chalk it up to a bad wizard error somewhere along the line.
