meta characters are not replaced as intended


Try this test:
        UriPattern p = UriPattern.Create("/LiveContacts/Contacts/Contact({ContactId})");
        IDictionary<string, string> values = p.Parse("/LiveContacts/Contacts/Contact(1001)");
        Assert.AreEqual<string>("1001", values["ContactId"]);
It will fail because in the UriPattern.BuildRegex the code is supposed to be doing a regex replace to escape all meta characters, but it actually just attempts a string replace, which does nothing.
The following lines fix the problem.
private static Regex regexMetaPattern = new Regex(@"[\[]()\&\^\$\?#+*\|>\<]", RegexOptions.Compiled); // This is a regex not a string
private static string regexMetaCharactersReplacements = @"\$0"; // Removed a slash here also
In UriTemplate.BuildRegex, change the template.Replace(...) to
template = regexMetaPattern.Replace(template,regexMetaCharactersReplacements) + ".*";
I looked at Snell's original code and the bug is there also.

Good catch... I once looked at that code and thought... no idea why it was being done, but my patterns never had things like your pattern. I've integrated you fix and will push a release tomorrow.

To be fair, it was my mistake in translating from the java original, since in java's string class, the replaceAll method expects a regex pattern, not a raw pattern. Mea Culpa
