1. Write any program that has compile error.
2. Select the error from Visual Studio's Error List.
3. It redirects to a Bing search instead of the corresponding documentation page.

For example:

public static class Program
{
    public static void Main()
    {
        Console.WriteLine("Hello, world") // CS1002
    }
}

Pressing F1 redirects to https://bingdev.cloudapp.net/BingUrl.svc/Get?selectedText=%3B%20expected&mainLanguage=C%23&requestId=467ec398-afbb-4220-9e73-f7bb0ed4f876&errorCode=CS1002, where it should redirect to https://msdn.microsoft.com/query/dev16.query?appId=Dev16IDEF1&l=EN-US&k=k(CS1002);k(DevLang-csharp)&rd=true.
