i try use azure mobile services simple forms app , don't work. last command run forever. checked internet connection webclient , okay. code works fine in simple windows console application.
var ms = new mobileserviceclient( @"https://xxx.azure-mobile.net/", @"xxx" ); imobileservicetable<todoitem> todotable = ms.gettable<todoitem>(); list<todoitem> items = todotable .where(todoitem => todoitem.complete == false).tolistasync().result; edit: use xamarin studio because have indie license. debug tried samsung galaxy s3 , huawei ascend p7, result same. have updated xamarin , produces interesting exception if use async-await result.

are sure not blocking ui combination of async / await (deadlock)? modify code follows:
imobileservicetable<todoitem> todotable = await ms.gettable<todoitem>(); list<todoitem> items = todotable.where(todoitem => todoitem.complete == false).tolistasync().configureawait(false); see here more information specific problem: http://blog.stephencleary.com/2012/07/dont-block-on-async-code.html
for further informations deadlock, stephen clary has excellent blog this: http://blog.stephencleary.com/2012/02/async-and-await.html
