The SqlDataProviderIssues.UpdateIssue(Issue issueToUpdate) includes a parameter when calling the stored procedure called "@ReturnValue" which is an int. I'm assuming this is supposed to represent a boolean value of whether the update was successful or not.
If my assumption is correct, then this value should be changed to a bit SqlDbType and it needs to be implemented in the stored procedure "Bugnet_Issue_UpdateIssue".
