How to fix the AppManifest.xml Designer can not be launched in Visual Studio 2015?

I got a bunch of update with visual studio in my development machine, and I try to open AppManifest.xml in designer mode. But nothing happen.

I need to close the visual studio 2015 and go the appData of Visual Studio 2015, then clear the Cache of ComponentModelCache

C:\Users\(MyUserName)\AppData\Local\Microsoft\VisualStudio\14.0\ComponentModelCache

then reopen the project. the AppManifest.xml can be viewed in Designer Mode.

Happy Programming.

Before:
Global
    GlobalSection(SolutionConfigurationPlatforms) = preSolution
        Debug|Default = Debug|Default
        Debug|Any CPU = Debug|Any CPU
        DebugLocal|Default = DebugLocal|Default
       DebugLocal|Any CPU = DebugLocal|Any CPU
       Release|Default = Release|Default
       Release|Any CPU = Release|Any CPU
    EndGlobalSection
    GlobalSection(ProjectConfigurationPlatforms) = postSolution
        {C840CD44-07C2-4B5D-A534-ED06A044DF1E}.Debug|Default.ActiveCfg = Debug
        {C840CD44-07C2-4B5D-A534-ED06A044DF1E}.Debug|Default.Build.0 = Debug
        {C840CD44-07C2-4B5D-A534-ED06A044DF1E}.Debug|Default.Deploy.0 = Debug
        {C840CD44-07C2-4B5D-A534-ED06A044DF1E}.DebugLocal|Default.ActiveCfg = DebugLocal
        {C840CD44-07C2-4B5D-A534-ED06A044DF1E}.DebugLocal|Default.Build.0 = DebugLocal
        {C840CD44-07C2-4B5D-A534-ED06A044DF1E}.DebugLocal|Default.Deploy.0 = DebugLocal
        {C840CD44-07C2-4B5D-A534-ED06A044DF1E}.Release|Default.ActiveCfg = Release
        {C840CD44-07C2-4B5D-A534-ED06A044DF1E}.Release|Default.Build.0 = Release

    EndGlobalSection
    GlobalSection(SolutionProperties) = preSolution
        HideSolutionNode = FALSE
    EndGlobalSection
       GlobalSection(SolutionConfigurationPlatforms) = preSolution
        Debug|Default = Debug|Default
        DebugLocal|Default = DebugLocal|Default
