Gibt es etwas, das ich über diese VS 2013-Ausnahme tun kann/sollte?

Question

Beim Laden meiner ASP.NET-App/Site, bekomme ich diese Fehlermeldung: "Eine Ausnahme wurde festgestellt. Dies kann durch eine Erweiterung verursacht werden."

Er sagt dann in dieser Datei suchen:

C: \ Benutzer \ Ton \ AppData \ Roaming \ Microsoft \ Visualstudio \ 11.0 \ ActivityLog.xml

... in dem ich drei das finden Einträge, die mit dem Problem zusammenhängen können, aber sie sind "Griechisch für mich". Aufgrund ihrer voluminosity, bin auch ich nur die erste hier:

Answer 1

Dieser Fehler oft durch eine Korruption im Cache gespeicherten Metadaten verursacht wird. Warum dies der Fall ist, weiß ich nicht, aber das Löschen den Cache wird in der Regel von Visual Studio zu arbeiten, um zurück:

• Visual Studio 2013 is unable to open the Test Window

Und dann wird diese Ausnahme auch auftreten, wenn Sie ein Visual Studio-Update installiert haben, 2,3 oder 4 und haben andere visuelle Studio-Teile (wie die Web-Tools), die gegen eine ältere Version gebaut wurden. Aktualisieren Sie auf die neueste Version in der Regel hilft auch einiges:
