Continuing in Visual Studio after Unity

When you open the solution in Visual Studio, you will see three different projects. If you only see one, you have opened the .sln file in the root folder. Trust me, this will happen quite often. The names are the same and the folders look quite similar. However, the one with the three projects is the one we can use to build and deploy; so, open that one. Again, this is found in the App folder you created and pointed at in the last step of the Build in Unity.
