SoapCoreServer

ASP .Net Core implementation of Soap Server. Supports part of features of WCF (Windows Communication Foundation) in .Net Framework 4.x.

Published on NuGet.org - https://www.nuget.org/packages/SoapCoreServer/.

Features

• Supports transfer modes: text, binary, stream+text, stream+binary
• Supports compress modes: binary+deflate, binary+gzip, stream+binary+deflate, stream+binary+gzip
• Supports transfer data in request headers (for DataContractSerializer mode only)
• Supports 2 serialization modes: DataContractSerializer and XmlSerializer
• Supports IsOneWay methods (returns void). But not like WCF - when IsOneWay=true returns empty response
• Generate wsdl schema compatible with generated by native WCF (SOAP 1.1 & 1.2, types inheritance, generic types, enums with numeric values)
• Supports async methods
• Supports different content encodings

Limitations

• Require declaration of attributes ServiceContract, OperationContract, DataContract, MessageContract for service interfaces
• Require declaration of attributes DataMember, MessageBodyMember, MessageHeaderMember for DataContractSerializer mode
• Require declaration of attributes XmlElement, XmlArray, XmlArrayItem for XmlSerializer mode
• ref/out parameters not supported
• Methods must contains no more than one parameter
• Methods parameters must be of complex types (string, int, long, etc not supported)

Usage

1. Service interface

[ServiceContract(Namespace = "http://soapcoreserver")]
public interface ISoapService
{
    [OperationContract(
        Action = "http://soapcoreserver/SendRequest",
        ReplyAction = "http://soapcoreserver/SendRequestResponse")]
    Task<SendRequestResponse> SendRequest(SendRequest sendRequest);
}

2. Service and data types implementation for DataContractSerializer mode

[DataContract(Name = "SendRequest", Namespace = "http://soapcoreserver")]
[MessageContract(WrapperName = "SendRequest", WrapperNamespace = "http://soapcoreserver", IsWrapped = true)]
[XmlType(Namespace = "http://soapcoreserver")]
public class SendRequest
{
    [DataMember(Order = 0)]
    [MessageBodyMember(Namespace = "http://soapcoreserver, Order = 0)]
    public string Message { get; set; }
}

[DataContract(Name = "SendRequestResponse", Namespace = "http://soapcoreserver")]
[MessageContract]
[XmlType(Namespace = "http://soapcoreserver")]
public class SendRequestResponse
{
    [DataMember(Order = 0)]
    [MessageBodyMember(Namespace = "http://soapcoreserver, Order = 0)]
    public string Message { get; set; }
}

public class SoapService : ISoapService
{
    public async Task<SendRequestResponse> SendRequest(SendRequest sendRequest)
    {
        return await Task.FromResult(
            new SendRequestResponse {
                Message = sendRequest.Message
            });
    }
}

3. SoapCoreServer register

using SoapCoreServer;

public class Startup
{
    public void ConfigureServices(IServiceCollection services)
    {
        ...
        services.AddScoped<SoapService>();

        // optional
        services.AddSoapExceptionTransformer(exception => exception.Message);
        ...
    }

    public void Configure(IApplicationBuilder app)
    {
        ...
        app.UseSoapEndpoint<SoapService>(new SoapCoreOptions()
                                                 .SetBasePath("/SoapService")
                                                 .AddEndpoint(new Endpoint("/text", MessageType.Text))
                                                 .AddEndpoint(new Endpoint("/gzip", MessageType.StreamBinaryGZip))
                                                 .SetSoapSerializer(SoapSerializerType.DataContractSerializer));
        ...
    }
}
