NotImplementedException from HistoryStream when using HttpListenerHost

[James Deery]

I'm trying to write some integration tests for my project using the
HttpListenerHost. Requests using GET are working fine, but I'm getting
a NotImplementedException when I POST data:

at OpenRasta.IO.HistoryStream.get_Length() in OpenRasta\IO
\HistoryStream.cs:line 61
at OpenRasta.IO.WrapperStream.get_Length() in OpenRasta\IO
\WrapperStream.cs:line 40
at OpenRasta.IO.LengthTrackingStream.get_Length() in OpenRasta\IO
\LengthTrackingStream.cs:line 33

baseUriStr, Stream stream, Byte[] bytes, Int32 byteCount, Encoding
encoding)

Encoding encoding)
at System.Xml.XmlTextReaderImpl..ctor(String url, Stream input,
XmlNameTable nt)

at OpenRasta.Codecs.XmlSerializerCodec.ReadFrom(IHttpEntity
request, IType destinationType, String parameterName) in OpenRasta
\Codecs\application\xml\XmlSerializerCodec.cs:line 26
at
OpenRasta.OperationModel.Hydrators.RequestEntityReaderHydrator.TryReadPayloadAsObject(IHttpEntity
requestEntity, IMediaTypeReader reader, IOperation operation) in
OpenRasta\OperationModel\Hydrators\RequestEntityReaderHydrator.cs:line
101

This all works fine when the code is hosted on IIS.

What can I do to make sure that the codec can read from the POST
request stream without getting an exception?

Oh, it looks like I'm running into this issue:

https://github.com/openrasta/openrasta-core/issues/14

Is there a work-around for this at the moment?

temporarily you can have your own xml seiralizer codec that either copies the stream into a memorystream before reading it, or pass a wrapper stream to the serializer that is not seekable.

Those changes from august have not been pulled back in as I stopped working for the client I was building those changes for rather quickly...
