`ArraySegment<T>` deserialization fails on .NET Framework #272

Closed dstelljes closed 11 months ago

dstelljes commented 1 year ago

ArraySegment<T> relies on an implicit conversion not available on Framework:

  Failed Chr.Avro.Serialization.Tests.ArraySerializationTests.ArraySegmentValues(value: [-10, 10, -5, 5, 0]) [2 ms]
  Error Message:
   Chr.Avro.UnsupportedTypeException : Failed to map ArraySchema[LongSchema] to System.ArraySegment`1[System.Int64].
---- System.InvalidOperationException : No coercion operator is defined between types 'System.Int64[]' and 'System.ArraySegment`1[System.Int64]'.
