C# .NET HttpResponseMessage Sensitive Information found in memory

Question

How can I prevent sensitive information found in memory after a HTTP Request in C# .NET?

I have written a Console Application (net6.0) which makes HTTP Request. After executing the app, I took a dump (using Task Manager) and found sensitive information (Data in HttpResponseMessage and username, password submitted via the HTTP Request).

How can I prevent sensitive information found in memory? (something like, make sure those data is not in plain text in the dump)

class Program
{
    static readonly HttpClient client = new HttpClient();

    static async Task Main()
    {
        try
        {

            Dictionary<string, string> values = new()
            {
                  { "email", "[email protected]"},
                  { "password", "alex"}
            };

            FormUrlEncodedContent content = new(values);

            HttpResponseMessage response = await client.PostAsync("https://fake-api-jwt-json-server.tvbishan.repl.co/auth/login", content);

        }
        catch (HttpRequestException e)
        {
            Console.WriteLine("\nException Caught!");
            Console.WriteLine("Message :{0} ", e.Message);
        }
    }
}
