CRM 2011 - Reflexive relationship must specify direction using ReflexiveManyToManyRelationship

When trying to retrieve data for reflexive relationship I was getting the exception which is the title of this post. How I was able to fix the same was by just using once line of code as below which will mention whether the role is referencing or referenced.

 

relationship.PrimaryEntityRole = EntityRole.Referencing;

 

where relationship is the object Relationship.

 

Hope this helped someone. !!!
