Im trying to make a relation with ASPNETUsers table and my custom table. ASPNetUsers will contain users who register and then Admin can chose from the list of Users and pick a User which will then become a employee. I didnt implement any logic to that yet because I dont know how to connect those tables. Im not looking for done code I just cant figure out how to connect this two.
On photos above you can see my DB and solution structure. AlgebraSchoolApp is MVC app with individual users accounts login. Entities contatin my models which are added in ApplicationDbContext inside AlgebraSchoolApp. DAL is just used for accesing data from DB (update,edit,delete functions).
