What advantage does using ysoserial.net provide for generating ViewState?

Using ysoserial.net skips the step of manually serializing XAML data. By compiling a modified version of ysoserial.net that outputs the Base64-encoded serialized XAML data, attackers can directly obtain the serialized payload. They then only need to compute the signature (using the same HMACSHA1 process) to generate the final ViewState, streamlining development and reducing dependencies as detailed in the original article.
