Description David Karlaš 2014-05-19 00:25:27 UTC
This sample works fine on .Net but fails on mono:

var httpClient = new System.Net.Http.HttpClient();
httpClient.DefaultRequestHeaders.Add("User-Agent", "MonoDevelop (Unix 3.13.0; amd64; en-US; Octokit 0.3.4)");

Problem seems to be in https://github.com/mono/mono/blob/master/mcs/class/System.Net.Http/System.Net.Http.Headers/ProductInfoHeaderValue.cs#L157
Which eats up beginning of comment "(" so on next loop FormatError occurs because parsing commented string...
