Signalr: client JavaScript non riuscire a ricollegare su IE (eccezione parseError)

Question

Configuration/Setup:

• Windows 7 a 64 bit, .Net 4.5, Visual Studio 2012
• Self-Host Signalr Server (console app)
• client JavaScript

Background:

Ho iniziato con this self host tutorial come base con l'obiettivo finale di configurare un server hub che possa connettersi a across domains (CORS). Sto usando principalmente la versione 2.0.0-rc1.

Repo Passi:

I passi di pronti contro termine sono facili. Passare alla pagina di prova (default.html) da good 'ol IE (versione 10) e attendere.

Qui ci sono i registri client signalr dettaglio ciò che accade:

Si può vedere che gli errori continuano a verificarsi e il cliente mantiene ricollegare fino a quando la ri-connessione non riesce.

Come bonus, ho creato un'applicazione Repro che è possibile scaricare dal SkyDrive here

Se qualcuno ha una certa comprensione per il mio problema o mi può puntare nella giusta diretta, sarebbe il mio giorno.

[UPDATE] Dei 5 sviluppatori che hanno cercato di riprodurre mediante il codice sorgente incluso zero sono riusciti a riprodurre.

Suppongo che a questo punto il mio problema sia specifico della mia macchina (duh?). Con questo presupposto, quale elemento ambientale potrebbe causare la "signalr/sondaggio? Transport = longPolling request to" abort "?

nota il commento da parte dell'autore: "Questo non è un bug E 'il design destinato abbiamo scelto La modifica di questa a un suggerimento.".

Answer 2

Si sta eseguendo Visual Studio come amministratore? Potrebbe avere a che fare con le autorizzazioni e Owin.
