I have a project in visual studio professional 2012 where I use the linq when I add a field to the database (in SQLServer) in the linq the new field appears in the image that I added I have the field
cuenta_sobrante
but it does not update the origin of data from the cuenta_bancos
table, the solution I found was to do it manually with the "configure data source with the assistant" button but it appears deactivated. What can I do to automatically update the data source again? Is it a visual studio error? Is there something in the code that prevents it from being updated?
