I have inherited some code where a call like:
var test = HttpUtility.HtmlDecode("google");
causes a stackoverflow. A call to WebUtility.HtmlDecode in the same place works fine. I've Googled around but not found anything about why this might be happening.
It is not a web application - and I see MSDN says to use WebUtility in this case - but other sources say I can just add a ref to System.Web and it will work fine - e.g. C# HTMLDecode without System.Web possible? I have built a test app and the same call to HtmlDecode works fine.
The stack trace is:
System.Web.dll!System.Web.HttpRuntime.StaticInit() Unknown

I'd like to understand the source of the problem if anyone knows the answer!
