             Summary: BinaryDecoder on NetStandard 2.1+ Fails To Read Large Strings
                 Key: AVRO-2983
                 URL: https://issues.apache.org/jira/browse/AVRO-2983
             Project: Apache Avro
          Issue Type: Bug
          Components: csharp
    Affects Versions: 1.10.0
         Environment: netstandard2.1+
            Reporter: Brian Davidson


In 1.10.0 support was added to use ArrayPool<byte>.Shared.Rent and ArrayPool<byte>.Shared.Return to get a buffer from the system.  

ArrayPool<T>.Rent(Int32) returns a buffer that is at least minimumLength in length, but can be more. 

The span that is used is Read into until it isEmpty, and when this buffer returned from ArrayPool is not exactly the same as the requested minimumLength this causes an exception


{code:java}
  Message: 
    Avro.AvroException : End of stream reached
  Stack Trace: 
    BinaryDecoder.Read(Span`1 buffer) line 97
    BinaryDecoder.ReadString() line 74 {code}
