ivy-create-soap-connection

Add a SOAP web service connection to an existing Ivy project. This skill guides you through collecting the WSDL URL, authentication details, and generating a typed client using dotnet-svcutil.

Pre-flight: Read Learnings

If the file .ivy/learnings/ivy-create-soap-connection.md exists in the project directory, read it first and apply any lessons learned from previous runs of this skill.

Reference Files

Read before implementing:

• references/AGENTS.md -- Ivy framework API reference (widgets, hooks, layouts, inputs, colors)

Step 1: Validate the Project

1. Verify this is a valid Ivy project. Check for a .csproj file and Program.cs in the working directory. If this is not an Ivy project, tell the user and stop.

2. Clean up any empty connection folders under Connections/ if they exist.

Step 2: Collect the WSDL URL

3. Ask the user for the WSDL URL if not already provided. The URL must be a valid HTTP or HTTPS URL (matching ^https?://.+$). If the URL is invalid, ask the user to provide a valid one.

4. Validate that the URL is accessible and points to a WSDL document.

Step 3: Collect Connection Details

5. Ask the user for a connection name in PascalCase (e.g. "PaymentService", "WeatherApi"). The name must match the regex ^[A-Z][a-zA-Z0-9]*$. A name is suggested based on the WSDL URL hostname. If the name is invalid or already in use, ask the user to provide a different one.

6. Ask the user for the SOAP service endpoint URL. This is the actual service URL that the client will call at runtime (not the WSDL URL). A suggestion is derived from the WSDL URL hostname.

7. Ask the user to select the authentication type:

Auth Type	Description	Required Credentials
none	No authentication	--
basic	HTTP Basic (username + password)	Username, Password
bearer	Bearer token	Token
custom-header	Custom header (name + value)	Header Name, Token/Value

8. Based on the chosen auth type, collect the required credentials:
   • basic: Ask for username and password (password is a secret)
   • bearer: Ask for the bearer token (secret)
   • custom-header: Ask for the header name and the header value (value is a secret)
   • none: No credentials needed

Step 4: Generate the Connection

9. Create the connection directory at Connections/[ConnectionName]/.

10. Ensure dotnet tools are installed. The dotnet-svcutil tool is required:

dotnet tool install --global dotnet-svcutil

11. Initialize user secrets and store credentials:

dotnet user-secrets init
dotnet user-secrets set "[ConnectionName]:EndpointUrl" "[endpoint-url]"

For auth credentials, also store them in user secrets:

• basic: [ConnectionName]:Username and [ConnectionName]:Password
• bearer or custom-header: [ConnectionName]:Token

12. Add the required WCF NuGet packages:

dotnet add package System.ServiceModel.Http
dotnet add package System.ServiceModel.Primitives

13. Run dotnet-svcutil to generate the client from the WSDL:

dotnet-svcutil [WsdlUrl] --outputDir Connections/[ConnectionName] --namespace "*,[ProjectNamespace].Connections.[ConnectionName]" --noLogo

This generates a Reference.cs file containing the service client class (inheriting from System.ServiceModel.ClientBase<T>).

14. Verify that Reference.cs was generated in the connection directory. If generation fails:
    • Verify that the WSDL URL is accessible and valid
    • Check that .NET SDK is installed and dotnet-svcutil is available
    • Verify the service uses SOAP 1.1 or 1.2

Create the ClientFactory

15. Create Connections/[ConnectionName]/[ConnectionName]ClientFactory.cs. This class reads credentials from configuration and creates the SOAP client with the appropriate binding and authentication:

using System.Reflection;
using System.ServiceModel;
using System.ServiceModel.Channels;
using System.ServiceModel.Description;
using System.ServiceModel.Dispatcher;
using Microsoft.Extensions.Configuration;

namespace [ProjectNamespace].Connections.[ConnectionName];

public static class [ConnectionName]ClientFactory
{
    public static [ServiceClientClassName] CreateClient()
    {
        var configuration = new ConfigurationBuilder()
            .AddEnvironmentVariables()
            .AddUserSecrets(Assembly.GetEntryAssembly()!)
            .Build();

        var endpointUrl = configuration.GetValue<string>("[ConnectionName]:EndpointUrl")
            ?? throw new Exception("[ConnectionName]:EndpointUrl is required");

        var endpointUri = new Uri(endpointUrl);
        Binding binding;

        if (endpointUri.Scheme == "https")
        {
            var httpsBinding = new BasicHttpsBinding();
            httpsBinding.Security.Mode = BasicHttpsSecurityMode.Transport;
            binding = httpsBinding;
        }
        else
        {
            binding = new BasicHttpBinding();
        }

        var endpoint = new EndpointAddress(endpointUrl);
        var client = new [ServiceClientClassName](binding, endpoint);

        // For basic auth:
        // var username = configuration.GetValue<string>("[ConnectionName]:Username")
        //     ?? throw new Exception("[ConnectionName]:Username is required");
        // var password = configuration.GetValue<string>("[ConnectionName]:Password")
        //     ?? throw new Exception("[ConnectionName]:Password is required");
        // client.ClientCredentials.UserName.UserName = username;
        // client.ClientCredentials.UserName.Password = password;

        // For bearer auth:
        // var token = configuration.GetValue<string>("[ConnectionName]:Token")
        //     ?? throw new Exception("[ConnectionName]:Token is required");
        // client.Endpoint.EndpointBehaviors.Add(
        //     new AuthHeaderBehavior("Authorization", $"Bearer {token}"));

        // For custom-header auth:
        // var token = configuration.GetValue<string>("[ConnectionName]:Token")
        //     ?? throw new Exception("[ConnectionName]:Token is required");
        // client.Endpoint.EndpointBehaviors.Add(
        //     new AuthHeaderBehavior("[HeaderName]", token));

        return client;
    }

    // Include these classes when using bearer or custom-header auth:

    private class AuthHeaderBehavior(string headerName, string headerValue) : IEndpointBehavior
    {
        public void Validate(ServiceEndpoint endpoint) { }
        public void AddBindingParameters(ServiceEndpoint endpoint, BindingParameterCollection bindingParameters) { }
        public void ApplyDispatchBehavior(ServiceEndpoint endpoint, EndpointDispatcher endpointDispatcher) { }

        public void ApplyClientBehavior(ServiceEndpoint endpoint, ClientRuntime clientRuntime)
        {
            clientRuntime.ClientMessageInspectors.Add(new AuthHeaderInspector(headerName, headerValue));
        }
    }

    private class AuthHeaderInspector(string headerName, string headerValue) : IClientMessageInspector
    {
        public object? BeforeSendRequest(ref Message request, IClientChannel channel)
        {
            var httpRequestProperty = new System.ServiceModel.Channels.HttpRequestMessageProperty();
            httpRequestProperty.Headers[headerName] = headerValue;

            if (request.Properties.ContainsKey(HttpRequestMessageProperty.Name))
            {
                request.Properties[HttpRequestMessageProperty.Name] = httpRequestProperty;
            }
            else
            {
                request.Properties.Add(HttpRequestMessageProperty.Name, httpRequestProperty);
            }

            return null;
        }

        public void AfterReceiveReply(ref Message reply, object correlationState) { }
    }
}

Uncomment and use only the auth section matching the chosen auth type. Remove the AuthHeaderBehavior and AuthHeaderInspector classes if auth type is none or basic.

The [ServiceClientClassName] is detected from the generated Reference.cs -- look for a class inheriting from System.ServiceModel.ClientBase<T> (e.g. SomeServiceClient). If detection fails, default to [ConnectionName]Client.

Create the Connection class

16. Create Connections/[ConnectionName]/[ConnectionName]Connection.cs implementing IConnection and IHaveSecrets:

using Ivy;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using System.Reflection;

namespace [ProjectNamespace].Connections.[ConnectionName];

public class [ConnectionName]Connection : IConnection, IHaveSecrets
{
    public string GetContext(string connectionPath)
    {
        var connectionFile = nameof([ConnectionName]Connection) + ".cs";
        var clientFactoryFile = nameof([ConnectionName]ClientFactory) + ".cs";
        var files = Directory.GetFiles(connectionPath, "*.*", SearchOption.TopDirectoryOnly)
            .Where(f => !f.EndsWith(connectionFile) && !f.EndsWith(clientFactoryFile))
            .Select(File.ReadAllText)
            .ToArray();
        return string.Join(Environment.NewLine, files);
    }

    public string GetName() => "[ConnectionName]";

    public string GetNamespace() => typeof([ConnectionName]Connection).Namespace!;

    public string GetConnectionType() => "Soap.Wsdl";

    public ConnectionEntity[] GetEntities()
    {
        var clientType = typeof([ServiceClientClassName]);
        var methods = clientType.GetMethods(BindingFlags.Public | BindingFlags.Instance | BindingFlags.DeclaredOnly)
            .Where(m => m.Name.EndsWith("Async"))
            .ToArray();

        return methods
            .Select(m => new ConnectionEntity(m.Name, m.Name))
            .ToArray();
    }

    public void RegisterServices(Server server)
    {
        server.Services.AddTransient(_ => [ConnectionName]ClientFactory.CreateClient());
    }

    public Secret[] GetSecrets()
    {
        return
        [
            new Secret("[ConnectionName]:EndpointUrl"),
            // For basic auth:
            // new Secret("[ConnectionName]:Username"),
            // new Secret("[ConnectionName]:Password"),
            // For bearer or custom-header auth:
            // new Secret("[ConnectionName]:Token"),
        ];
    }

    public async Task<(bool ok, string? message)> TestConnection(IConfiguration config)
    {
        try
        {
            var client = [ConnectionName]ClientFactory.CreateClient();
            return (true, null);
        }
        catch (Exception ex)
        {
            return (false, $"Connection test failed: {ex.Message}");
        }
    }
}

Adjust the GetSecrets() method to include only the secrets relevant to the chosen auth type.

Expected directory structure after completion:

[UserProject]/
├── [UserProject].csproj
├── Program.cs
├── Connections/
│   └── [ConnectionName]/
│       ├── [ConnectionName]Connection.cs
│       ├── [ConnectionName]ClientFactory.cs
│       └── Reference.cs (generated by svcutil)

Step 5: Verify

17. Run dotnet build to verify everything compiles. Fix any errors.

18. Run dotnet build to verify the project compiles. Then test the connection by running dotnet run and verifying the app starts without errors. If the test fails, investigate and fix the issue.

19. If the project is in a git repository, create a commit with a descriptive message, for example: "Added SOAP connection '[ConnectionName]'."

20. Tell the user the connection is ready and show them how to use it. Example usage:

public class SomeView : ViewBase
{
    public object? Build()
    {
        var client = UseService<[ServiceClientClassName]>();
        // Call SOAP operations, e.g.:
        // var result = await client.SomeOperationAsync(request);
        ...
    }
}

Recovery

If the setup fails:

1. Diagnose the root cause (invalid WSDL URL, svcutil failure, incompatible SOAP version, auth issues):

   • For invalid WSDL location: verify the WSDL URL is accessible or the file path exists
   • For svcutil failure: check that .NET SDK is installed and dotnet-svcutil is available
   • For SOAP version issues: verify the service uses SOAP 1.1 or 1.2 (WS-* extensions may not be fully supported)
   • For auth issues: check if the SOAP service requires WS-Security or HTTP auth

2. After fixing the underlying issue, either retry using the /ivy-create-soap-connection skill from scratch, or manually create the connection:

   • Run svcutil manually: dotnet-svcutil [wsdl-url] --outputDir Connections/[ConnectionName]/
   • Add the generated classes to your project
   • Configure the SOAP client endpoint and binding in code
   • Implement authentication if required (WS-Security, HTTP Basic, etc.)
   • Test the connection with a sample SOAP operation

3. Use ivy ask "How do I create a SOAP connection?" or ivy ask "How do I configure SOAP authentication?" for API guidance.

Post-run: Evaluate and Improve

After completing the task:

1. Evaluate: Did the build succeed? Were there compilation errors, unexpected behavior, or manual corrections needed during this run?
2. Update learnings: If anything required correction or was surprising, append a concise entry to .ivy/learnings/ivy-create-soap-connection.md (create the file and .ivy/learnings/ directory if they don't exist). Each entry should note: the date, what went wrong, why, and what to do differently next time.
3. Skip if clean: If everything succeeded without issues, do not update the learnings file.
