XAML Designer crashes Object reference not set to an instance of an object

问题 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

Unable to cast object of type 'Castle.Proxies.XProxy' to type 'X' in WPF Designer

问题 I've recently discovered the very useful design time attributes from Blend for a WPF component, which (among other things) allows you to set a DataContext only at design time. Awesome! Combined with the DesignInstance attribute, you can set a type to be automatically created and bound to during design time, allowing you to use the Visual Studio Designer with some context as to what your WPF component will actually look like at run time. Its really nice, and I wish it hadn't taken me so long

问题 One of my XAML files shows a strange behaviour in the XAML designer (but not during runtime): public class MyDesignTimeViewModel { public MyDesignTimeViewModel() { MyText = "abc"; MyInt = 5; } public string MyText { get { ... } } public int MyInt { get { ... } } } Then in XAML: <UserControl xmlns:d="http://schemas.microsoft.com/expression/blend/2008" ... d:DataContext="{d:DesignInstance vm:MyDesignTimeViewModel}" > <TextBlock Text="{Binding MyText}" /> <TextBlock Text="{Binding MyInt}" /> <

Can Visual Studio XAML designer handle font family names with spaces as a resource?

由 馋奶兔 提交于 2019-12-11 03:43:54
问题 This probably seems like a strange question, but I'm having trouble seeing a custom true-type font that I've loaded as a resource in my WPF application, and I'm wondering if it may have to do with the space in the font name. As described elsewhere (one of hundreds of examples), I've added the font to a folder Fonts in my application, and set it to Build Action = Resource . I'm able to reference the font (e.g., in a TextBlock ) with a simple FontFamily="Fonts\#My Font" . Unfortunately, the

WPF designer doesn't run window static constructor upon starting up

由 好久不见. 提交于 2019-12-07 14:47:46
问题 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
