Process.StandardOutput.Peek() and Process.StandardError.Peek() hang until StreamReader receives data.

Closing this issue because I cannot reproduce it reliably.

The original issue suggested to repro the problem using the Process.StandardOutput which is suboptimal because most of the processes we usually run produce some output. The issue shows itself only when output is empty. Just try the same but with the Process.StandardError. In most of the cases there will be no data in that stream and the issue will reproduce.

    var process = Process.Start(new ProcessStartInfo("path\to\executable.exe", arguments)
    {
        CreateNoWindow = true,
        UseShellExecute = false,
        RedirectStandardInput = true,
        RedirectStandardOutput = true,
        RedirectStandardError = true,
        StandardOutputEncoding = Encoding.UTF8,
        StandardErrorEncoding = Encoding.UTF8
    });

    var outputBuilder = new StringBuilder();
    while (process.StandardError.Peek() > -1)
        outputBuilder.Append((char)process.StandardError.Read());
    var result = outputBuilder.ToString();
