Visual studio 2015
问题:为了在Windows资源管理器中查看我自己的格式文件的预览，自定义预览处理程序库是使用4.0框架构建的，并使用regasm.exe注册了.一切正常.
Issue : For viewing the preview of my own format files in windows explorer , custom preview handler library is built using 4.0 framework and registered using regasm.exe. Everything works well.
问题出在app.vshost.exe [在Visual Studio Framework 4.0及更高版本中打开控制台应用或Windows应用时]，previewhost.exe无法启动.如果Visual Studio已关闭或框架更改为3.5或更小，prevhost.exe正在运行.
The problem is with app.vshost.exe[when a console app or windows app is opened in visual studio framework 4.0 and later],previewhost.exe is not firing.if visual studio is closed or framework change to 3.5 or lesser, prevhost.exe is working.
