c# - Using HttpClient.GetAsync to call Web API seems to hang -

i'm working on proof of concept prototype.
have asp.net c# web form (visual studio 2013, .net 4.5) page. on button click this:

list<blog> blogs = null; protected void btnloaddata_click(object sender, eventargs e) {     //...;      switch (int.parse(rbldatasource.selectedvalue))     {         //...;          case 4:             runasyncblogs().wait();              break;          default:             blogs = localgetter.getblogs();             break;     }      //...; } 

runasyncblogs looks this:

static async task runasyncblogs() {     using (var client = new httpclient())     {         client.baseaddress = new uri("http://localhost/wapidemo/");         client.defaultrequestheaders.accept.clear();         client.defaultrequestheaders.accept.add(new mediatypewithqualityheadervalue("application/json"));          // http         httpresponsemessage response = await client.getasync("api/blogs");         if (response.issuccessstatuscode)         {             list<blog> thisbloglist = await response.content.readasasync<list<blog>>();             var cnt = thisbloglist.count();         }      } } 

the code stops @ response = await client.getasync call. when stops, debugger acts request has ended, browser still waiting.

if run console app (i copy , paste runasync() method it) calls web api same way, data. so, believe web api app responding expected.

this:

 runasyncblogs().wait(); 

is deadlocking code. synchronously blocking async method call trying marshal continuation on implicitly captured synchronization context. why shouldn't block on async code

protected async void btnloaddata_click(object sender, eventargs e) {    // other stuff    await runasyncblogs(); }
