Commented Unassigned: SQL CE :: when trying to scaffold a migration that uses MapToStoredProcedures on SQL CE, we create migration with empty body, rather than throwing earlier [1154]

I have a simple model targeting Sql CE:

public class Customer
{
public int Id { get; set; }
public string Name { get; set; }
}

public class MyContext : DbContext
{
public DbSet<Customer> Customers { get; set; }
}



I scaffold a migration, all works fine.

Then I try to add mapping to stored procedures:

protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
modelBuilder.Entity<Customer>().MapToStoredProcedures();
}



Wen I scaffold a new migration, we create something like this:


public override void Up()
{
CreateStoredProcedure(
"Customer_Insert",
p => new
{
Name = p.String(maxLength: 4000),
},
body: ""
);

CreateStoredProcedure(
"Customer_Update",
p => new
{
Id = p.Int(),
Name = p.String(maxLength: 4000),
},
body: ""
);

CreateStoredProcedure(
"Customer_Delete",
p => new
{
Id = p.Int(),
},
body: ""
);


Which throws the following error during Update-Database:

Sql CE does not support Stored procs, so I don't expect this to work, but I would expect for us to fail more gracefully (detect that we are targeting CE and throw before scaffolding a corrupted migration)
Comments: This is just a bug - The fluent APIs should not validate the body parameter; it is allowed to be null or whitespace. I have a fix for this already so we should just triage it for EF6.
