Description

I am unable to use Microsoft.ML.OnnxRuntime.Managed with MAUI, it works on a regular net6.0 library, and latest Xamarin Forms.
Error: Reference to type 'ReadOnlySpan<>' claims it is defined in 'mscorlib', but it could not be found

Steps to Reproduce

1. Create a new MAUI project, Android is what I tested on
2. Add Nuget reference to Microsoft.ML.OnnxRuntime.Managed and Microsoft.ML.OnnxRuntime
3. Add workaround for a different ONNX bug: net6.0-android generated sources compile error(don't support covariant for return value ) #3867 (comment)
4. Add this code somewhere: new DenseTensor<float>(4);
