how do i stop build solution when its stuck my laptops slow if it's faulty program it will take long time before finding the error but instead i want to stop it in the middle of building the solution is it possible it will save alot of time
This is IDE-specific. SInce you are using the term "solution" I assume that you are in visual studio. In that case use CTRL+Break. It's the only time that I ever use that button.
If you are on a laptop without a break key, then in one of the menus, (I think it's the project menu) you can select "stop build".
