Understanding .NET Core HttpClient.GetStringAsync

Question

I want to understand what the following code is doing (it's from a tutorial):

        string token = await _httpClient.GetStringAsync("example-data/token.json");

My understanding is that _httpclient is used to call a Uri. Is this code making a network trip at all? What is the Uri here? What is returned?

HttpClient can be initialized with a BaseAddress, after which any URLs supplied to the various GetBlah methods can be relative to that (which is what appears to be the case here). GetStringAsync will return the response as a string.

So the base address is set like this: new HttpClient { BaseAddress = new Uri(builder.HostEnvironment.BaseAddress) }); so it is "/". What does that resolve to for HttpClient?
