.NET 5.0 and SOAP Web services

Finally managed to figure it out whilst I was writing this question! Thought I'd still post it encase helped any others out.

The problem:

I'm upgrading my Windows Service from .NET Framework 4.x to .NET 5.0 which uses Hangfire to automate scheduled tasks in .NET and one of the tasks is talking to web service within SAP.

One of the automated jobs consumes SOAP service from SAP I but can't use it in .NET 5.0 or .NET Core 3.1 but I can use it with .NET Framework

There is quite a few bespoke SAP services we're consuming. However, this is the most simple one. Here is the WSDL (Did remove the binding URL and identity property):

Any ideas on way to consume this SOAP within .NET 5.0? I mean worst-case scenario we move it to OData but ideally like to tackle that at a later date.

I've tried to add it using the WCF Service reference which I get the following error:

The optional WSDL extension element 'Policy' from namespace 'http://schemas.xmlsoap.org/ws/2004/09/policy' was not handled.
XPath: //wsdl:definitions[@targetNamespace='urn:sap-com:document:sap:soap:functions:mc-style']/wsdl:portType[@name='Z_DATA_FEEDS']/wsdl:operation[@name='ZOrderStatus']

That added an assembly of System.ServiceModel to the project but complaining about .NET version so been compiled for the different framework.

Answer:

  • Right click on the Connected Services and click Add
  • Click on Microsoft WCF Web Service Reference Provider
  • Put your URI in and whatever options and click next/finish
  • Remove the System.ServiceModel as it's not compatible with .NET 5.0
Install Package System.ServiceModel.Http
Install-Package System.ServiceModel.Primitives

For my type of service, it's basic authentication:

var basicHttpBinding = new BasicHttpBinding();
basicHttpBinding.MaxBufferSize = int.MaxValue;
basicHttpBinding.ReaderQuotas = System.Xml.XmlDictionaryReaderQuotas.Max;
basicHttpBinding.MaxReceivedMessageSize = int.MaxValue;
basicHttpBinding.AllowCookies = true;
basicHttpBinding.OpenTimeout = TimeSpan.FromMinutes(15);
basicHttpBinding.ReceiveTimeout = TimeSpan.FromMinutes(15);
basicHttpBinding.SendTimeout = TimeSpan.FromMinutes(15);

basicHttpBinding.Security.Mode = BasicHttpSecurityMode.TransportCredentialOnly;
basicHttpBinding.Security.Transport.ClientCredentialType = HttpClientCredentialType.Basic;

var endpoint = new EndpointAddress("## Enter your URL ##");

using (var client = new Analytics.ZWS_ANALYTICSClient(basicHttpBinding, endpoint))
{
    client.ClientCredentials.UserName.UserName = "## Your username ##"
    client.ClientCredentials.UserName.Password = "## Your password ##";

    // Call your web service method here
}

Hopefully, this will help someone out in a similar situation to me.
