VS 2013 MVC 4.5 defekte Referenzen

Question

Ich habe ein MVC 4.5 C# -Projekt in Visual Studio 2013. Es lief perfekt ohne Fehler, bis ein Kollege begann, mit mir zu arbeiten.

Die VS-Version meines Kollegen war 2015, und als er (über TFS) mit meinem Projekt synchronisiert wurde, sieht es so aus, als ob alle meine Referenzen kaputt gegangen wären. Jetzt erkennt VS meine Razor-Tags nicht mehr und gibt mir viele Fehler und Warnungen.

Je nach Anzahl der Dateien öffne ich die Liste der Fehler und Warnungen werden größer. Hier ist ein Beispiel, wie es aussieht, wenn ich öffnen Sie einfach die Hauptansicht des Projekts:

Warning 101 Found conflicts between different versions of the same dependent assembly that could not be resolved. These reference conflicts are listed in the build log when log verbosity is set to detailed. 

Warning 103 Unknown element 'lmweb_mvc.models.leaseviewmodel' or element cannot be placed here.

Wenn Sie NuGet verwenden Ich schlage vor, Sie zu machen

Update-Package –reinstall
