Title: Parse metadata only if it sent as text

Sending metadata as text adds a lot of overhead over the network (due " encoding) and on clientside due manual JSON.parse.
Your controller can simply return the Metadata as json by specifying the contentType header:

i.e.
```csharp
[HttpGet]
public HttpResponseMessage Metadata()
{
var result = new HttpResponseMessage { Content = new StringContent(_contextProvider.Metadata())};
result.Content.Headers.ContentType = new MediaTypeHeaderValue("application/json");
return result;
}
```
