Problem: Generally when we auto generate Schema using biztalk WCF consume adapter service with help of the category Strongly-Typed Procedure then received following error-

 TypedProcedure/dbo/ProcedureName' ---> System.Data.SqlClient.SqlException: The error description is 'XML document must have a top level element.'.
Could not find prepared statement with handle 0.

Solution:  Open your store procedure and put FMTONLY in the following way before temporary table

DECLARE @FMTOnlySet bit;
SELECT @FMTOnlySet = 0 WHERE 1 = 1               
IF @FMTOnlySet IS NULL
SET FMTONLY OFF;
-- start temp table code here

-- end temp table code here
IF @FMTOnlySet IS NULL
SET FMTONLY ON;
