Why can't Entity Framework see my Stored Procedure's column information?

Question

I have the following stored procedure and when I attempt to Function Import it says my Stored Procedure returns no columns. What am I missing? Any Suggestions?

The Proc:

ALTER PROCEDURE [healthc].[ev_kc_Products_Search]
(
    @SearchString   VARCHAR(1000)
)
AS
SET NOCOUNT ON

    DECLARE @SQL    VARCHAR(max),
        @SQL1   VARCHAR(max),
        @Tag    VARCHAR(5)

    CREATE TABLE #T
    (   ID      INT,
        VendorName  VARCHAR(255),
        ItemName        VARCHAR(255),
        Type        VARCHAR(2),
        Sequence        TINYINT
    )


 SET @SQL = '

    INSERT  #T

    SELECT  VendorID ID,
        Name VendorName,
        NULL ItemName,
        ''V'' Type,
        0 Sequence
    FROM    tblVendors
    WHERE   '+REPLACE(@SQL1,@Tag,'Name')+'

    UNION ALL

    BLAH BLAH BLAH'


 EXEC(@SQL)


 SELECT ID, VendorName, ItemName, Type FROM #T

Try adding this line to the beginning of your stored procedure:

SET FMTONLY OFF

You can remove this after you have finished importing.
