xaml-designer

When I load solution and there is an opened designer tab for some window, then this window static constructor is not executed. Perhaps my conclusion is wrong (because I am absolutely clueless how designer load things), but here is a test case: Create new WPF project. Create simple extension public class MyExtension : MarkupExtension { public static bool Test; public override object ProvideValue(IServiceProvider serviceProvider) => Test.ToString(); } Add to main window <TextBlock Text="{local:My}" /> and static MainWindow() { MyExtension.Test = true; } Now compile it ( F6 ), TextBlock should

I'm developing a UWP app with Visual Studio 2015, and one of the things I want to do use some sample data at design time. Now, I've added a XAML file, set the build action as DesignDataWithDesignTimeCrateableTypes My XAML is really straight forward here: <local:Freead xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:MyNamespace.Uwp.Windows.ViewModels" xmlns:ad="clr-namespace:MyNamespace.Classifieds;assembly=LocalAngle.Uwp" ItemName="Java books" Description="Free to anyone that wants them.

I'm using Visual Studio 2015 Community. So, I created a blank UW App (C++) and I wanted to start looking around, because that's my first time using the XAML Designer. However, with no changes to the code whatsoever, the designer won't load. The Designer returns an unhandled exception (System.NullReferenceException) - Object reference not set to an instance of an object. This is really weird, as the app compiles and runs fine. The designer gives me a fix ("Excluding project code from running in the design view can improve the stability of the XAML designer...."), but this doesn't resolve the

I'm using thbe Microsoft Ribbon for WPF (System.Windows.Controls.Ribbon) and VS2015. Since I removed unnecessary depencies from my project (like Dynamic Data Display etc, things not related to the ribbon) it does not render correctly in the Designer anymore. All RibbonButtons get rendered as usual buttons and so on. I used the Clean Solution option and also rebuild multiple times, without sucess. While execution everything is fine, just the designer can't handle the ribbon anymore. What could have caused this strange behaviour? This is how my ribbon looks now in the designer: And this is how

Problem is if this process doesn't exist, build fails. I try to write something like this tasklist /nh /fi "imagename eq XDesProc.exe" | find /i "XDesProc.exe" && ( TASKKILL /F /IM "XDesProc.exe" ) || ( echo XAML designer is not running ) But ERRORLEVEL is equal to 1 too and bild fails if XDesProc.exe is not running. You could use a conditional test on the PID to avoid this: taskkill /f /fi "pid gt 0" /im xdesproc.exe 来源： https://stackoverflow.com/questions/15748355/how-to-kill-process-that-may-not-exist-on-prebuild-step-in-visual-studio
