Building Facebook. Yoga for UWP and WPFWeve been working with Blue. Jeans to port react native windows to WPF to complement the existing support for UWP. Facebook recently open sourced Yoga, a cross platform layout library that implements a subset of CSS, namely flexbox. The React Native framework for i. OS and Android switched to use Yoga we saw this as an opportunity to bring greater parity to react native windows. Background. When we first started developing react native windows, we considered a number of options to support the same flex layout properties on Windows as were available on i. OS and Android. We considered mapping these concepts to XAML panel types e. Grids and Stack. Panels but assumed that it would be a very complicated solution. Fortunately, the work done on the flex layout algorithm for i. OS, called css layout, had already been transpiled to Java and C by the open source community, so we were able to use it. Pokemon Season 15 Black. Later, the flex layout algorithm was reimplemented in C to support a more complete, well tested, cross platform implementation of the flexbox specification. The resulting implementation also included a Java API wrapper that was used in React Native for Android.

Executables that use the DELAYLOAD option dont implicitly link to the DLLs. Over the years, the Visual C compiler has undergone many changes, along with changes in the C language itself, the C Standard Library, the C runtime CRT, and. HU0q.png' alt='Dumpbin.Exe Microsoft' title='Dumpbin.Exe Microsoft' />Since the architecture for react native windows closely follows that of React Native for Android, we kicked off an effort to port that Java wrapper to C. When creating the UWP project, we could have either built the yoga. Windows Runtime Component or DLL. We took the latter approach and built a C wrapper with PInvoke for a few reasons. In the transpiled css layout algorithm, we were able to derive subclasses of Css. Node. We wanted to continue to support this pattern, and with CCX, you cannot have a managed class inherit from a CCX type. Also, while Blue. Jeans had demonstrated how CCX code could be shared with CCLI for compatibility with WPF, we wanted to use as simple an approach as possible that mirrored other React Native platforms use of Yoga. Using PInvoke would be the simplest way to target platforms other than Win. RT. The Problem. As mentioned above, the initial. NET wrapper when Yoga was still the css layout project was developed specifically as a UWP library. The C files for Yoga were imported into a Universal Windows DLL project, and a Universal Windows C class library was used for the PInvoke declarations and C API wrapper. Shortly after we started this work, Facebook announced that the project would be rebranded Yoga, and the project has grown well beyond the scope of React Native. When the project changed to Yoga, we transitioned the C class library to a. NET Standard library in collaboration with Blue. Jeans engineers. This change was useful because the library could now be used across. NET Framework for WPF and. NET Core for UWP, as well as Xamarin. We also pivoted from the Universal Windows DLL project for C to a Win. Initial testing showed that this approach worked on all target operating systems for react native windows currently, Windows 7, 8. There was also the added benefit that we only had to publish and test the Nu. Get package for a single. NET flavor for react native windows. The Nu. Get package we released for Yoga worked great on desktop. However, when we tested the app on the Windows 1. Dll. Not. Found. Exception on the first API call to Yoga. Looking at the output in binx. Debug, it was clear that yoga. DLL itself. It was strange that the x. Debugging. We first wanted to confirm that this wasnt a problem with deploying yoga. App. X bundle, as the deployment mechanism for mobile devices and emulators was slightly different than it was for desktop. We produced the App. X Bundle from Visual Studio and used the Power. Shell script to install the app on desktop to try and reproduce the Dll. Not. Found. Exception. Unfortunately, this did not reproduce the issue. We then found an issue on an open source project related to SQLite that sounded similar to our issue. A user reported that their x. The thread concluded that the issue was related to a dynamic reference to the C runtime where a static reference was required. It turned out that it was trivial to change from a dynamic to a statically linked C runtime by using the MT flag. This could be configured from the project build properties in Visual Studio. However, after we rebuilt yoga. Nu. Get package to ensure it deployed correctly on the mobile emulator, we had the same Dll. Not. Found. Exception. We started taking a closer look at binary itself. We used dumpbin. exe to confirm that yoga. We ran the command below and confirmed this was not the issue. Microsoft R COFFPE Dumper Version 1. Copyright C Microsoft Corporation. All rights reserved.

After discovering this issue, we quickly realized we couldnt use a standard Win. DLL for UWP in general, even though it was working fine for UWP Desktop. We likely would have found the same issue with builds for ARM devices, Xbox, and Holo. Lens. The Solution. Debugging was the hard part. To solve the problem, we had to create a separate C project file to produce separate binaries for Win. UWP. The two. vcxproj files were identical except for the globals section.
