In visual studio I created a solution with class library project and UWP project. But when I hit the F5 Key to build the UWP app which references the class library, the class library does not build. I have to manually build the library in order to see the changes. How to automatically build the class library when I press the F5
You can achieve this by going to solution properties (right click on solution in Solution Explorer > Properties) and there in Project Dependencies
tab you have to select your app in combobox and check that it depends on your class library.
