When you call stored procedure with select and output parameters and you don't select on some conditions (for example, you're just returning an error code) — you get a mapping EntityCommandExecutionException. This package fixes this annoying behavior of EF by returning empty data set and letting you read output parameters.

Example:
Consider you have this sql procedure:

CREATE PROCEDURE [dbo].[Foo]
   @Condition int = NULL,
   @ResultCode Int = NULL OUTPUT
AS
BEGIN
   IF @Condition IS NULL BEGIN
       SET @ResultCode = 1;       -- return 1 if condition = null
       RETURN;
   END
   SELECT 1 as 'One', 2 as 'Two'; -- select otherwise
   SET @ResultCode = 0;
END

Calling this procedure in EF:

var resultCodeParameter = new ObjectParameter("ResultCode", typeof(int));
var result = db.Foo(null, resultCodeParameter).FirstOrDefault();
var resultCode = resultCodeParameter.Value;

will throw an exception:
System.Data.Entity.Core.EntityCommandExecutionException: The data reader is incompatible with the specified 'xxx.Foo_Result'. A member of the type, 'One', does not have a corresponding column in the data reader with the same name.

Calling EntityFix.Load() once on your application start will fix this bug.
