I’m looking to use TLS 1.2 on a call Webclient in the framework .NET 2.0

It is possible?

try
{
    using (System.Net.WebClient client = new System.Net.WebClient())
    {
        string u = client.UploadString(url, xml);
        return u;
    }
}
catch (Exception ex)
{
    throw ex;
}
c# .net security-guard webclient tls

It is not possible, at least directly, only in 4.5 upwards. O . NET 2.0 has not been supported for quite some time and should not be used, it does not receive security updates.

Who knows how to catch the source and adapt for use (but it is not something trivial).

Use and improve the code:

using (var client = new WebClient()) {
    return client.UploadString(url, xml);
}

I put in the Github for future reference.

Much simpler, right? Capturing the exception is only causing problems for the code. Just capture the exception to make something useful. What you’re doing is just spoiling the stack trace.
