Easily update all proxy classes
Currently, there is no easy way to update all the existing proxy classes (with their respective option sets). Right now I have to select all the class files in the solution explorer, right click, then click 'CRM -> Regenerate...'
Maybe there could be an option group called 'Proxy Classes' in the context menu for the project where you can either add proxy classes or regenerate all

You can right click on the project and then "CRM -> Download files from CRM" and this will update all your proxy classes.
Yes having the same problem.
