HttpUtility.UrlEncode in .net core

Question

I am migrating from .net framework to .net core. In my current application I have:

private static string ToBase64Url(string value) => ToBase64Url(Encoding.UTF8.GetBytes(value));

private static string ToBase64Url(byte[] value)
{
  var s = HttpServerUtility.UrlTokenEncode(value).ToCharArray();
  return new string(s, 0, s.Length - 1);
}

I tried changing that to:

private static string ToBase64Url(byte[] value)
{
  var s = HttpUtility.UrlEncode(value).ToCharArray();
  return new string(s, 0, s.Length - 1);
}

However that gives me different results:

test data:

var text = {"alg":"RS256","typ":"JWT"};

result in .net framework: eyJhbGciOiJSUzI1NiIsInR5cCI6IkpXVCJ9

result in .net core: %7b%22alg%22%3a%22RS256%22%2c%22typ%22%3a%22JWT%22%7

what should be the right equivalent here?

Using the link above I created shorter version that worked for me:

private static string ToBase64Url(byte[] value) =>
            Convert.ToBase64String(value).Replace('+', '-').Replace('/', '_').TrimEnd('=');
