Rendering a map off-screen

Previously using the ArcGIS WPF Runtime I could create and initialize a map off-screen and render it to a bitmap using RenderTargetBitmap. I'm wondering if there is a preferred method to doing this as I'm currently unable to get a MapView to render unless it's in view, which isn't an option for this use case.


// Sample code

Grid grid = new Grid(){Width=width, Height=height};


Map map = new Map(){Width=width, Height=height};




grid.Measure(new Size(width, height));

grid.Arrange(new Rect(new Size(width, height)));



map.Extent = someExtent;


RenderTargetBitmap rtb = new RenderTargetBitmap(width, height, dpi, dpi, PixelFormats.Default);



// Do something with the image here


// End Sample


The sample above is a simplified version of what I'm doing, but the fundamentals are the same. In the .NET 10.2.7 runtime this results in blank images. How can I recreate this behavior in the .NET Runtime? It appears that the map is never initialized unless I bring it into view.
