Entity Framework The ALTER TABLE statement conflicted with the FOREIGN KEY constraint

Question

On updating database in Entity Framework , Code first Migration, I am getting this error:

The ALTER TABLE statement conflicted with the FOREIGN KEY constr

Answer 1

Assuming your migrations are in correct order i.e. table associated with Foreign key will get created before the reference. Follow the following steps:

1. Backup current database from SQL management studio (If required)
2. Delete database from SQL management studio
3. Type 'Update-Database'in Visual Studio 'Package Manager Console'
