Hi

In my application I have displayed a MessageDialog when the 'Did you mean to switch between Apps?' dialog is already displayed by OS... When i try to d this App throws 'UnAuthorizedAccessException'... How to solve this problem?

or How to find the 'Did you mean to switch between Apps?' dialog is displaying programmatically? & Hide this dialog?

Can anyone suggest me a solution?

Welcome to the Developing Universal Windows apps forum!

Please read the sticky posts, especially the Guide to posting: subject line tags and Known Issues for Windows 10 SDK and Tools

You can't show a MessageDialog when another modal dialog is already showing. There isn't a direct way to query that case, but you can probably watch the CoreWindow.Activated event or just handle the exception and know to try again later.
