I have Dot Net Framework 3.5 Web Service: http://www.dneonline.com/calculator.asmx I want to consume it on dot Net Core (3 or 6, any version).

When I run the program, it throws exception: PlatformNotSupportedException: Configuration files are not supported

Is it technically possible or not to call WCF Dot Net Framework 3.5 from any Dot Net Core application?

My mentor gave me an article that provided the answer. Mister Khalidabuhakmeh does a great job explaining how to consume SOAP APIs in .NET Core; thank you!

To summarize their steps:

1. Check if you installed .NET Core 2.1; if not, download from Microsoft and install.

2. Open Visual Studio 2019 or Visual Studio 2022.

   • Create a .NET Core Console App.
   • Go to View, then click Terminal.
   • At the terminal, input:

     dotnet new tool-manifest
     

3. At the Terminal, input:

   dotnet tool install dotnet-svcutil
   

4. At the Terminal, input:

   dotnet dotnet-svcutil https://www.dataaccess.com/webservicesserver/TextCasing.wso
   

If you have synchronous operations and you do have synchronous operations, then:

4. At Terminal input:

   dotnet dotnet-svcutil https://www.dataaccess.com/webservicesserver/TextCasing.wso --sync
   

   More information

   or

   Input the other WSDL link:

   dotnet dotnet-svcutil <wsdl url>
   

5. Consume SOAP:

    static async Task Main(string[] args)
    {
    var client = new TextCasingSoapTypeClient(
        TextCasingSoapTypeClient.EndpointConfiguration.TextCasingSoap,
        "https://www.dataaccess.com/webservicesserver/TextCasing.wso");
   
    var result =
        await client.AllLowercaseWithTokenAsync("THIS IS A STRING", "");
   
    // result: this is a string
    var value = result.Body.AllLowercaseWithTokenResult;
   
    Console.WriteLine(value);
   }

I got the same error with http://www.dneonline.com/calculator.asmx. How I solve it was by adding to the constructor

CalculatorSoapClient.EndpointConfiguration.CalculatorSoap

or

CalculatorSoapClient.EndpointConfiguration.CalculatorSoap12

i.e.

public static int add(int x, int y){
    CalculatorSoapClient client = new CalculatorSoapClient(CalculatorSoapClient.EndpointConfiguration.CalculatorSoap);
    return client.Add(x, y);
}

I should add that I didn't edit Reference.cs as suggested in here!
