error: PlatformNotSupportedException: Configuration files are not supported or How .NET Core 6 consume SOAP .NET Framework wcf

Question

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?

Answer 1

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: --sync

   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);
   }
