I want to access a web page in a Windows Forms app via SOAP.

Unfortunately, the compiler spits out many errors after I added the WCF Web Service to the project. What am I doing wrong here? The possible options don't tell me anything. The examples I found on the Internet could not help me with the errors.

Visual Studio Community 2022

WCF Web Service URI: https://www.onlinembe.de/wsdl/OnlineMbeSOAP.wsdl
