wcf: ProtocolException with iOS .NET 6.0 Application: The number of bytes available is inconsistent with the HTTP Content-Length header.
From @DuncWatts on Mon, 05 Sep 2022 12:20:03 GMT
I’m porting some code over from an existing Xamarin.Forms application however the WCF client I’ve written fails when run as a .NET 6.0 iOS application.
As WCF connected services don’t work within iOS due to the restrictions on emitted code, I use a reference generated by the Silverlight tooling as a workaround and add System.ServiceModel.Http to use it.
Steps to Reproduce
I’ve found a random soap service to demonstrate this (http://www.dneonline.com/calculator.asmx?WSDL) and created a .NET Standard 2.0 class library that contains the WCF client and the code that calls it. I’ve then created a simple .NET 6.0 iOS application and a Xamarin.iOS application that executes that code that calls the webservice. In the Xamarin.iOS application it can correctly call the webservice while the .NET 6.0 iOS application fails with the stack trace below.
Expected Behavior
Web service is called correctly
Actual Behavior
Exception thrown when calling web service:
[0:] System.ServiceModel.ProtocolException: The number of bytes available is inconsistent with the HTTP Content-Length header. There may have been a network error or the client may be sending invalid requests.

Removing the Content-Length header using a DelegatingHandler works a charm thank you. The previous workaround of setting UseNativeHttpHandler to false did work but triggered a lot of errors with the linker which I was struggling to resolve.
Yeah, that looks like a bug to me. Please file it. With info if it is specific to iOS, or general. And ideally with a standalone repro for us to act on. Thanks! cc @MihaZupan @ManickaP @CarnaViire
