Answer 3

esta mensagem não dá a menor pista =/

Você validou se a tabela Usuário existe? Já tentou efetuar a operação sem usar async para ver se a mensagem de erro é diferente?

Answer 4

Thiago,

A tabela esta criada no database Azure, tirei o async e continua gerando o mesmo erro ao tentar logar-se no app.

Só para te explicar melhor sobre o app, minha ideia inicial era criar um app de comparacao de preco e inicialmente ele teria uma tela de login (utilizando o azure) e existiria tambem duas tabelas para armazenar itens e produtos.

Thiago,

agora esta gerando esse erro aqui?

Answer 6

pela mensagem é um erro de enconding. Ao que parece existe alguma palavra com acento ou 'ç' e está dando este erro. Só para eu entender, este erro retorna ao tentar executar aquela mesma linha?

App.MobileService.GetTable.... ?

Answer 7

Sim está gerando na mesma linha.

O que estou achando estranho é que hoje deu outro erro:

Answer 8

alguma vez funcionou? existem dados na tabela? minha sugestão:

Instale o fiddler e monitore o request / response. Aparentemente há uma divergência de encoding.

Answer 9

Nenhuma vez funcionou.

Existe usuário cadastrado na base de dados do Azure. Cadastrei na "mão" mesmo.

Vou tentar isso. Obrigado!
