The types of all properties in the Dependent Role of a referential constraint must be the same as the corresponding property types in the Principal Role

web_services[1]Some days before I got an error while try to update migration like :

UploadedData_GrpCategory_Target_UploadedData_GrpCategory_Source: : The types of all properties in the Dependent Role of a referential constraint must be the same as the corresponding property types in the Principal Role. The type of property ‘Category’ on entity ‘UploadedData’ does not match the type of property ‘Id’ on entity ‘GrpCategory’ in the referential constraint ‘UploadedData_GrpCategory’.

 

 

I didn’t understand what it is in first look.  Then I understood , I created Primary key and foreign key in different datatypes in Entities.
