I installed the new .NET Provider and tried to update my EDMX Model (with Database First) but I am getting the following in my output window:

Unable to generate the model because of the following exception: 'An error occurred while executing the command definition. See the inner exception for details.

SQL error code = -204

Implementation limit exceeded
COLUMN DSQL internal
		Dynamic SQL Error

COLUMN DSQL internal

Writing the .edmx file took 00:00:00.0012551.

                  and f.rdb$field_type=t.rdb$type 
                  and t.rdb$field_name='RDB$FIELD_TYPE')) then
	execute statement 'drop DOMAIN BOOLEAN;';

    	AS SMALLINT DEFAULT 0

SET TERM ; !!


COMMIT TRANSACTION;

In my Database I have
