The modern way (for .net 5 and 4.x) is:

using System.Net.Http.Json;  // add the NuGet package

private HttpClient client = new HttpClient();
private async void MyForm_Load(object sender, EventArgs e)
{           
    MyClass data = await client.GetFromJsonAsync<MyClass>(api);
    ...
}

do not Dispose the HttpClient.

The package is not part of the default WinForms template, add System.Net.Http.Json from NuGet.

Make HttpClient static and it looks perfect

You can initialize a static Lazy<HttpClient>, if necessary. A default HttpClientHandler can be setup directly with a Lambda.

I got this Error: "Http" does not exist in System.Net!

You have to Add the System.Net.Http.Json nuget package. See the comment.

When you make the HttpClient static, you should also consider to make it readonly.
