Using DirectX to Render 2D Text Glyphs only render on Left Camera

This issue is related to this thread: https://forums.hololens.com/discussion/891/only-single-camera-is-found-by-debugging-whats-the-point-to-use-a-hashmap-to-maintain-camera-res

Basically I only ever get 1 camera and thus the Text is only rendered on the left eye. Please help. How do you get to the right camera? Is this a bug?

Figured this out. For DirectX UWP - you must render to both stereoscopic views. The DirectX UWP Holographic example gives you the hint.
1. When rendering draw using the instancedIndex()
2. In your shader (5.0 and above) use the SV_InstanceID semantic to toggle between a 0 and 1, which potentially represents Left and Right.
3. Create a ViewProjectMatrix array in the shader, and use the toggled Left and Right states to retrieve the Left and Right ViewProjections.
4. Set the RenderTargetArrayIndex in the shader to the index corresponding left and right viewprojection matrix.
5. Use a constant buffer and to store the ViewProjectionMatrix [2] array.
6. Populate the viewProjectMatrix array with the Float4x4 matrix from the cameraPose View Transform (Left and Right) matrices.
7. Set the viewPort for the camera (See the UpdateViewProjectionBuffer() method in the default Holographic example)
