async function in mvc4 vb.net - vb.net

Question

i have the below structure :
this is my controller :
Public Function InsertRegistration() as string
dim res = t.Insertregistration(jsonparam.status)
return res
End Function
this is my class :
Public Function InsertRegistration(byval status as string) as string
sql.Insertregistration(status)
return "1"
End Function
this is my model function :
Public Function InsertRegistration(ByVal status As String) As Boolean
Dim TConnSQL As New SqlConnection(sql)
Dim CommSQL As New SqlClient.SqlCommand("JK_SP_INSERT_PROFILE", TConnSQL)
Dim paramSQL As SqlClient.SqlParameter
Dim data_ada As SqlDataAdapter
Dim dt As DataSet
Try
CommSQL.CommandType = CommandType.StoredProcedure
paramSQL = New SqlClient.SqlParameter("#STATUS", SqlDbType.NVarChar, 100)
paramSQL.Direction = ParameterDirection.Input
paramSQL.Value = STATUS
CommSQL.Parameters.Add(paramSQL)
CommSQL.ExecuteNonQuery()
InsertRegistration= True
Catch ex As System.Data.SqlClient.SqlException
WriteToText("Nbl.InsertRegistration", ex.ToString)
InsertRegistration= False
Catch ex As Exception
WriteToText("Nbl.InsertRegistration", ex.ToString)
InsertRegistration= False
Finally
If (IsNothing(CommSQL) = False) Then CommSQL.Dispose()
If TConnSQL.State <> ConnectionState.Closed Then TConnSQL.Close()
End Try
End Function
is there a way to return the result 1 in an asynchronous way that the function sql.Insertregistration(status) keeps running in background after i return the result to the client?

Answer 1

Simply put your function sql.Insertregistration(status) as in below code:
(new Task<bool>(() =>
{
return sql.Insertregistration(status);
})).Start();
Note: Please take care of the cross thread ooperations.
