I need a sample C# VS 2015 WPF with an example of how to do loading a DevExpress in a background thread using .Net 4.5+ methods. I do not expect to see the backgroundworker as a solution. The WPF app should be a simple layout with a button that when clicked will have an animated loading icon and the DevExpress grid should load. The app GUI should remain responsive since the data is being loaded in the background. A sample SQL Server 2016 database will be provided and the app will call a stored procedure. The developer can download the latest trial DevExpress WPF grid and could use Adventure works database instead if preferred providing that the sample calls a stored procedure. The grid needs only to display a few columns but should have a large of enough number returned rows to be a complete demo.
