Conversion to generic interface breaks CCWs for collection types

[Sergio0694]

Describe the bug

To Reproduce

Triggered by this ItemsSource binding. The viewmodel property is this one.

public ShaderRunnerViewModel[] ComputeShaderOptions { get; } = ...

Works.

public IReadOnlyList<ShaderRunnerViewModel> ComputeShaderOptions { get; } = ...

Crashes.

Note

I've tried using an array expression instead of a collection expression, I still get the same exact crash.

Stack trace

Expected behavior

Should work fine

Latest from staging/AOT (016e9ec)

Additional context

Possibly related to #1661.

Ignoring the collection expression issue which is tracked separately, this looks to be because we are failing to detect the get property initializer it seems. Doing the below instead does work.

public IReadOnlyList<ShaderRunnerViewModel> ComputeShaderOptions { get; } =

->

public IReadOnlyList<ShaderRunnerViewModel> ComputeShaderOptions = new ShaderRunnerViewModel[]
