title: Informix Stored Procedures with Entity Framework Issue
body: <p>I am trying to import stored procedure into the entity model using database first approach and import fails due to the following warning. I am using Visual Studio 2015 update3</p>
  
  <p><strong>Error 6005:</strong> <em>The funtion 'ar_get_contact_name' has a return data type 'varchar' that is currently not supported for the target Entity Framework version. The function was excluded.</em> </p>
  
  <p><strong>Error 6046:</strong> Unable to generate function import return type of the store function 'ar_get_contact_name'. The function will be ignored and the function import will not be generated.</p>
  
  <p><strong><em>Table and SP as follows</em></strong></p>
  
  <p><em>create table "entityframework".ar_contact
    (
      contact_code char(10) not null primary key,
      name char(80) not null
    );</em></p>
  
  <p>CREATE PROCEDURE 'entityframework'.ar_get_contact_name ( 
  cont_code LIKE ar_contact.contact_code)</p>
  
  <p>RETURNING
  VARCHAR(50);</p>
  
  <p>DEFINE cont_name VARCHAR(255);</p>
  
  <p>SELECT 
      ar_contact.name
    INTO
      cont_name
    FROM 
      ar_contact
    WHERE 
      cont_code = contact_code;</p>
  
  <p>RETURN cont_name;</p>
  
  <p>END PROCEDURE</p>
  
  <p>Is there any workaround for this?</p>
