Error occured while Entity Framework generating model - entity-framework

Question

I'm having very few tables in my edmx (not more than 20)
I'm having big list of stored procedures (may be more than 1k) in my edmx.
EF version 5.0
Whenever I try to add/update model from DB it always throw this error, can any one help me out with this?
Unable to generate the model because of the following exception:
'System.Data.Entity.Core.EntityCommandExecutionException: An error
occurred while executing the command definition. See the inner
exception for details. ---> System.Data.SqlClient.SqlException: The
incoming request has too many parameters. The server supports a

Answer 1

This kind of error is usually caused by to many object in a model (look like this is the case with all your procedures) and Entity Framework is not smart enough to make multiple database round trip.
