title: Visual Studio Does not notice code changes
body: <p>I'm currently working on a WPF project in visual studio but I have the problem that when I press <kbd>F5</kbd> my it does not build my code it just runs the previous build. It seems like Visual Studio ignores the fact that I change my code.<br>
  Luckily pressing <kbd>Ctrl</kbd>+<kbd>Shift</kbd>+<kbd>b</kbd> builds the solution but it's annoying when you press <kbd>F5</kbd> by mistake and expect it to build and it doesn't.<br>
  I have Checked the <strong>"Options->Project and Solutions->Build and Run->On Run"</strong> and it is set to always build and <strong>"Build"</strong> is checked for my project in the build configuration manager.</p>
