Solution 1

You can do it this way: Create a stored procedure to count the number of the records on your table. Return that value to the C# application. From there, you can add 1 to the returned value and concatenate it to the EMP.

This is not good: what if a record is deleted? Then the next number will be a one already used. The EmployerID must be kept in another table in order to make it unique.
