Let’s write some code to load the resources. In each of the resource files I’ve added a string resource for WelcomeText (apologies if my French isn’t correct as I just used a translation tool since I don’t speak French). The two files we’re going to add are and, which as you might have guessed are going to correspond to resources for English (US) and French (CA). resw files so that they’re compatible with MRT Core. Now that we’ve initialized the SDK, the next thing we’re going to do is add a couple of resource files to the application. ThrowExceptionForHR( unchecked(( int)hr)) Var hr = NativeMethods.MddBootstrapInitialize( 1 << 16 | 0, "experimental1", 0) In the constructor for the MainWindow, we just need to call the MddBootstrapInitialize method public MainWindow( ) Public static extern uint MddBootstrapInitialize( uint majorMinorVersion, The following NativeMethods class is added as a private class within the MainWindow class. We’re going with a slightly simpler mechanism that imports a single method that is used to initialize the SDK. The documentation for this isn’t great at the moment but there are some good samples, such as the C# WinForms Unpackaged sample that shows how to initialize the SDK. After doing this, the project will build as you’d expect.īefore we get started creating any resources, we need to add some logic to our application to initialize the Windows App SDK. This issue is easily resolved by opening the Configuration Manager and then simply clicking Close to persist the default settings. The cause seems to be a misalignment in the build configuration – prior to the update the project was set to build as An圜PU after the update, the project doesn’t have an An圜PU platform, instead it has x86, 圆4 and arm64. = Rebuild All: 0 succeeded, 0 failed, 1 skipped = You can right-click on the project and select Rebuild but all you see in the output window is Rebuild started.ġ>- Skipped Rebuild All: Project: MRTCoreSample. If you attempt to build the project at this point you may see a slightly weird behaviour from Visual Studio where it refuses to build the updated project. Make sure you click the Reload projects button in order for the Windows App SDK references and other property changes to take effect. When you save the changes to the csproj, you’ll most likely see a prompt across the top of the Visual Studio editor indicating that you need to reload one or more projects. Again, these are required in order for the Windows App SDK to be included in the application. You’ll also notice that we’ve updated the TargetFramework to include the SDK version and set the TargetPlatformMinVersion. The first thing we’re going to do is add references to the Windows App SDK and specify the platforms and runtime identifiers for the application (these are required since the Windows App SDK is a native library that targets specific platform architectures, so doesn’t support An圜PU). This process should work with existing applications so long as they’ve been updated to run on. The initial csproj contains only the bare bones required for our application, which in this case is running on. Let’s get started with a basic WPF application, MRTCoreSample, which is based on the WPF Application template in Visual Studio. Note that if you’re using WinUI3 the resource management for images, strings etc that are referenced from XAML is all automatic, so you shouldn’t need to write custom logic such as this example. The same technique will work with any Win32 based application such as WinForms, or even a WinUI3 based application. I’m going to walk through how to create and manage resources in a WPF application using MRT Core. If you’re using the stable release at the time of writing you’ll still need to distribute your application using a packaging project. An unpackaged application doesn’t require a separate packaging project. In this post we’re going to look at how the Windows App SDK makes resource management easy for win32 based applications such as WinForms and WPF.Ī quick side note before we get started – the example in this post uses the new “unpackaged” application capability that’s available in the experimental release of the Windows App SDK. This is where the resource management capabilities of UWP kicks in, allowing you to define resources in different files and for the appropriate resources to be loaded based on the runtime properties of the application. Where this all gets complicated is where you need to deal with different screen resolutions, or different languages. You might think this is quite simple as images are just files that are packaged with your app and strings can just be put in a constants file. As a UWP developer I relied heavily on the framework to deal with managing application resources such as images and string literals.
