我的 UWP 项目中的 XAML 设计器未加载。它给出了以下错误。

System.TypeLoadException
Method 'GetStylePropertyTargetType' in type 'Microsoft.VisualStudio.DesignTools.WindowsXamlDesigner.Metadata.WindowsUIXamlPlatformMetadata' from assembly 'Microsoft.VisualStudio.DesignTools.UniversalXamlDesigner, Version=14.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' does not have an implementation.

有人能帮我吗？

我尝试了所有类似问题中可用的解决方案，但仍然没有结果。

正如他们在这里提到的

Programs and features -> Microsoft VS2015 -> Select Change -> Goto Modify 并检查是否确实安装了 SDK v1.3。如果它没有尝试安装它并仔细检查安装文件并确保现在安装了 sdk v1.3。如果它不是安装并一遍又一遍地检查最后是成功的。如果您最终成功安装 SDK v1.3，您的 XAML 设计器问题肯定会消失

所以这个问题可以通过安装 SDK v1.3 来解决，请确保您已经安装了它，我强烈建议您在安装 SDK 后修复 Visual Studio。
