While these initial efforts will not comprehensively solve the entire problem space, our aim is to unblock customers and make the transition to a 64-bit Visual Studio 2022 smoother. NET Framework applications in the latest Visual Studio environment. Recognizing the limitations imposed by this shift, and its impact on our developers, we have been working hard on features to pave the way for designing legacy WinForms 32-bit. Until now, the workaround for such scenarios was to use Visual Studio 2019, where the Windows Forms designer operated as a 32-bit process, accommodating the specific needs of these projects. NET Framework projects that extensively leverage ActiveX/COM controls or other custom controls embedded in 32-bit assemblies. This specific hurdle has emerged as a significant adoption blocker for users with Windows Forms. NET Framework projects that rely on 32-bit references, a consequence of the inherent technical limitation where the 64-bit devenv.exe Visual Studio process cannot load 32-bit compiled references. The challenge lies in the inability to design Forms in. NET Framework projects using the Windows Forms designer in Visual Studio 2022. However, this evolution brings with it a notable challenge for some. As Klaus Loffelmann describes in his blog post, this transition enhances overall performance and responsiveness, particularly when working with resource-intensive tasks and large codebases. The default list of devices is by no means complete, but you can easily extend it by creating your own XML-based device definitions.Visual Studio 2022’s transition to a 64-bit architecture, driven by customer feedback across the full range of Visual Studio developers, marked a pivotal step towards enhancing the development experience. The XAML designer is very useful to avoid having to rebuild the entire project when working on the app layout. You can download the 4'' phone definition shown above here. Once you load the designer, you will find your new device listed among others. Once we are satisfied with our new device definition, we can copy it to the "1033" directory alongside the others and restart Visual Studio. Orientation qualifier - pipe-separated list of orientations the device supports, Portrait and Landscape seem to be the only options that are actually reflected in the designer Size - the diagonal size of the device's display in inchesįinally, we can also define some qualifiers inside the element:ĭeviceFamily qualifier - the device family, can be either Mobile, Desktop, Xbox, IoT, HoloLens or PPI (which stands for Surface Hub) Scale - scaling factor in percents, must be either 100, 125, 150, 200 or 400 Height - physical height of the screen in pixels Width - physical width of the screen in pixels Name - name that will be displayed in the list The file structure is very self-explanatory. I recommend you to copy the file to Desktop or other accessible location, because you will otherwise need to grant yourself permissions before trying to save the modified XML file in Program Files. The easiest way to start creating a new device definition is to just copy one of those already existing. Let's try to create a new custom device that will be very similar to the Lumia 520 - 4 inch display with 480 x 854 pixels and 150% scaling factor, which yields the smallest supported effective screen size for UWP Mobile - 320 x 569. You can see that they are plain simple XML files, named #_name.xml, where # is a number that is supposedly used just for ordering purposes and name is used for easy identification. The full path C:\Program Files (x86)\Windows Kits\10\DesignTime\UAP\Devices\1033 is where all the design device definitions reside. If we open it and go into "Devices/1033", we will finally reach our final destination. This folder contains "CommonConfiguration" directory (which contains the default control templates, styles and theme resources for built-in XAML controls), and also the "UAP" directory. This folder is definitely browse-worthy, but the most interesting for us in this case is the " DesignTime" folder. On this location we will find the "10" folder, which is the home of UWP SDKs. The default place where the Windows SDK files are installed is C:\Program Files (x86)\Windows Kits. Is it possible to expand the selection with more devices?ĭefault device offering in Visual Studio Where are the devices defined?įirst thing we need to do is to find the place where the device definitions are stored. Unfortunately, the default selection might not be sufficient for you in some cases, especially when you want to optimize for a specific screen. The Visual Studio XAML Designer for Universal Windows Platform offers design-time device previews for several different screens size and scaling combos.
