Dealing with the "Failed To Sign" Error in Visual Studio 2017
ATTENTION Visual Studio Developers: After upgrading to latest Release Candidate (RC) for Visual Community 2017, we encountered an Error regarding signing and certificates when updating our older apps from previous versions of Visual Studio. Right-clicking the line for Show Error Help was essentially useless, as was a internet search for solutions. For simple applications, the solution is quite easy and takes just seconds. If your project requires signing and certificates, then this is still a good starting point as it will show you where to begin.
