Questo errore mi fa impazzire e non riesco nemmeno a riprodurlo!Il sito Web di Azure non può accedere a Azure DB
Ho pubblicato il mio sito Web su Windows Azure e SQL Azure e ha funzionato benissimo. Tutto l'improvviso e non funziona, ottengo questo brutto errore:
Ecco l'errore che ottengo:
http://jsfiddle.net/shimmy/pcS7g/embedded/result
Ecco l'errore:
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)
voglio per sottolineare che posso accedere a SQL tramite SSMS o VS e vedere le mie tabelle ecc.
Non ho idea di cosa causa questo fastidioso errore succede ancora e ancora dopo ogni dispiegamento.

Aggiornamento
Ecco una copia delle stringhe di connessione come appaiono sul web.config del server:
<connectionStrings>
<add name="Context" connectionString="Data Source=tcp:abcdefg.database.windows.net,1433;Initial Catalog=Database;User [email protected]:abcdefg;Password=my123password;" providerName="System.Data.SqlClient" />
<add name="Storage" connectionString="DefaultEndpointsProtocol=https;AccountName=accountname;AccountKey=accountkey==" />
</connectionStrings>
Ho anche cercato di rimuovere completamente le stringhe di connessione dal web.config del server. Non ho idea di dove arrivi questa cosa App_Data
!
mio DbContext
assomiglia a questo:
public Context()
: base("name=Context") //I also tried "Context" alone
{
}
È strano. Potresti eseguire l'rdp delle istanze e controllare in web.config per assicurarti di utilizzare stringhe di connessione corrette? – Win
Sono abbastanza nuovo in questo, come puoi rdp un server Azure? – Shimmy
