Core 3.1 for WinForms System.Net.WebClient Upload.String(string,string,string) overload is broken #43013

Closed Budsy closed 3 years ago

Budsy commented 4 years ago

The bug: (.NET Core 3.1 winforms VS project)

System.Net.WebClient.UploadString(string url, string method, string payload) nor the Uri,string,string overload will not compile. Intellisense shows the overload option as documented for Core 3.1, but shows warning and won't compile.

To Reproduce

Simply open a VisualStudio2019 project for .NET Core 3.1 winforms and try to construct:

System.Net.WebClient client = new System.Net.WebClient(); var response = client.UploadString(url,"POST","{'hello':'goodbye'}");

Exceptions not reproduceable because this code will prevent compilation.

System.Net.WebClient was deprecated and removed, instead you need to use System.Net.HttpClient.

System.Net.WebClient was deprecated and removed

It was obsoleted in .NET 5, but it wasn't removed. It's still there and not marked as obsolete in .NET Core 3.1.

To Reproduce

I did this and it compiles fine for me. Can you share your repro project that fails to compile?
