Metal call to CreateRenderPipelineState fails on tvOS

[addr010]

Steps to Reproduce

1. Create the sample tvOS metal project
2. Build and Run project on Apple TV

Expected Behaviour

Project runs

Actual Behaviour

The pipelineState is null and sample fails

snippet from sample.
pipelineState = device.CreateRenderPipelineState(pipelineStateDescriptor, out error);
if (pipelineState == null)
Console.WriteLine("Failed to created pipeline state, error " + error);

the error is: "Target OS is incompatible"

Works in my existing apps for iOS and macOS.

I can't progress on tvOS version of my app at this point.

Any workarounds?

Hello, I can reproduce your issue with our current template, I have no workaround for you but it seems that some of the options passed to MTLRenderPipelineDescriptor the native API is no longer liking them, seems that our template is out of date
