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?

I had this issue, what I had to do was create a User-Defined Table Type and return that.

CREATE TYPE T1 AS TABLE 
(  ID      INT,
    VendorName  VARCHAR(255),
    ItemName        VARCHAR(255),
    Type        VARCHAR(2),
    Sequence        TINYINT
);
GO

Your Stored Procedure will now look like this:

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

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

@T [schema].T1

SET @SQL = 'SELECT  VendorID ID,
    Name VendorName,
    NULL ItemName,
    ''V'' Type,
    0 Sequence
    FROM    tblVendors
    WHERE   '+REPLACE(@SQL1,@Tag,'Name')+'
    UNION ALL
    BLAH BLAH BLAH'

INSERT INTO @T
EXEC(@SQL)

SELECT ID, VendorName, ItemName, Type FROM @T
