"Build Solution" has no effect

I have created new classes in the Unreal Engine and after I’ve edited them in Visual Studio (I’m using Microsoft Visual Studio Community 2013) I used to press “Build Solution” under the Build-tab. This used to compile the code which was then reloaded in the Unreal Editor.
For some time, possibly since I installed UE 4.8, when I press “Build Solution” I get a message that the build was successfull, but my changes are never loaded in the Unreal Editor. Furthermore, the success-message appears almost immediately which makes me doubt if the code is even compiled. Back when building the solution worked it usually had to load for a while before the compilation was finished. Pressing the “Compile”-button in the Unreal Editor works fine, but I would still like to be able to compile through Visual Studio.

is your visual studio attached to the unreal engine process? if it is, go to the editor and click “compile”. If not, you need to start the editor from visual studio, that is how it’s setup now I think.

I\m pretty sure it is attached, pressing “compile” works, it’s just that pressing “build solution” inside of Visual Studio used to work as well, but now it doesn’t, even though I get a success-message when I press it
