Visual Studio 2015 WPF XAML编辑器无法打开XAML文件 [英] Visual Studio 2015 WPF XAML Editor cannot open XAML files

问题描述

我最近从Visual Studio 2015更新到了Visual Studio 2015 Update 2(专业版).一切正常，除了我无法打开XAML文件的事实-单击任何XAML文件后，我得到:

I have recently updated from Visual Studio 2015 to Visual Studio 2015 Update 2 (Professional). Everything works fine except the fact that I can't open XAML files - after clicking on any XAML file I get:

Visual Studio has encountered an unexpected error.

似乎尚未安装XamlDesignerPackage. XamlEditor条目在HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\14.0 \下不存在，而在HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\14.0 \下存在 HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\12.0\，可能表明该Visual Studio 2015未安装XAML设计器.

It looks that XamlDesignerPackage hasn't been installed. XamlEditor entry doesn't exist under HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\14.0\ and it exists under HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\12.0\ which may suggest that XAML Designer is not installed for this visual studio 2015.

我已经尝试了一切:

• 4个重新安装
• 清理缓存
• 删除ComponentDataCache
• 重置设置.

在Visual Studio 2013中，一切正常.有没有一种方法可以使用VS2013中的XAMLEditor?您有什么想法我可以做什么?我会很高兴为您提供任何帮助，因为它使我无法工作.这是来自ActivityLog.xml的错误:

In Visual Studio 2013 everything works fine. Is there a way to use XAMLEditor from VS2013? Do you have any ideas what I can do? I would be glad for any help since it prevents me from working. This is an error from ActivityLog.xml:

我发现在编辑器条目下的HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\12.0_Config\中存在以上guid.似乎尚未安装设计器，因为vs 2013中存在该设计器.一定存在冲突.

I have found that above guid exists in HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\12.0_Config\ under Editors entry. It looks like designer hasn't been installed because it exists in vs 2013. There must be a conflict.

我已经删除了2013和2015并安装了2015，并且在运行Visual Studio 2015时收到以下消息:

I have removed both 2013 and 2015 and installed 2015 and getting the following message when running Visual Studio 2015:
