Creating A Windows 10 Game With Azure

Exciting times! Starting today, Windows 10 is available for everyone: During the next twelve months, people can upgrade for free if they’re running Windows 7 or Windows 8 on their machine. What’s in it for us?

Well, we can see that Microsoft’s efforts of rewriting the Windows kernel over the past few years have really paid off: With Windows 10, universal apps enable each and every one of us to develop a single app and run it on phones, desktops and consoles alike!

Universal Windows Platform

I found that this is the perfect time to start a new big blog series about developing multi-platform online games. In this series, we’ll learn how to build a classical strategy game on Windows 10 using a (free!) Microsoft Azure backend. Azure enables us to create a backend that scales to arbitrary user counts, is easy to connect to various client platforms (not just Windows) and comes with full tool support for maximum productivity. Azure is a huge platform, and this can really be a little overwhelming – it was for me, and I think it will be even for more experienced developers. So we’re going to go through this step by step.

We’ll talk about building and deploying client and server, authenticating users, implementing the game logic itself on both sides, and sending push notifications, among others. Whenever you’ve got any questions, or are aching to see a specific feature, just add your thoughts to the comments below!

Okay – let’s do this!

APPX3104 after upgrading your Windows Store app to Windows 10

In my previous post I started talking about potential issues you might face when upgrading C++ Windows Store apps to Windows 10 Technical Preview along with Visual Studio 2015 Preview.

Another thing that might occur when trying to deploy your app on your local machine is the following error:

error APPX3104: You cannot create an app bundle when building for platform ‘x86’ which is not included in the list of platforms selected for producting app bundle. Set platform to a one of following values: arm.

Note that this error doesn’t occur when deploying directly for your ARM devices, such as your Microsoft Surface or your Windows Phone.

This happens due to an entry in your .vcxproj file which has most likely been created by Visual Studio 2013:

Removing that entry will allow you to deploy for all platforms again. In fact, this line won’t be present if you create a new Visual C++ DirectX Windows app from scratch in Visual Studio 2015 Preview.

MSB3774 after upgrading your Windows Store app to Windows 10

If you’ve recently installed the Windows 10 Technical Preview along with Visual Studio 2015 Preview, you might encounter the following compiler error after having upgraded your C++ Windows Store app:

error MSB3774: Could not find SDK “Microsoft.VCLibs, Version=14.0”

Chances are that Visual Studio automatically changed the Platform Toolset of your project:

Platform Toolset

This may be pointed out by your version control system as well as the only change in your project file after the upgrade:

Changing it back to Visual Studio 2013 (v120) (or <PlatformToolset>v120</PlatformToolset> in the project file) might resolve that issue for you.
