SOLVED!
Ogromne podziękowania dla Sam LeachNie można wczytać zestawu System.Threading.Tasks przy użyciu interfejsu API Kalendarza Google
Oto przykład z mojego pliku app.config roboczego:
<configuration>
...
<runtime>
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<dependentAssembly>
<assemblyIdentity name="System.Threading.Tasks" publicKeyToken="B03F5F7F11D50A3A" culture="neutral"/>
<bindingRedirect oldVersion="0.0.0.0-2.5.19.0" newVersion="2.5.19.0"/>
</dependentAssembly>
<dependentAssembly>
<assemblyIdentity name="System.Net.Http" publicKeyToken="B03F5F7F11D50A3A" culture="neutral"/>
<bindingRedirect oldVersion="0.0.0.0-2.1.10.0" newVersion="2.1.10.0"/>
</dependentAssembly>
<dependentAssembly>
<assemblyIdentity name="System.Net.Http.Primitives" publicKeyToken="B03F5F7F11D50A3A" culture="neutral"/>
<bindingRedirect oldVersion="0.0.0.0-2.1.10.0" newVersion="2.1.10.0"/>
</dependentAssembly>
</assemblyBinding>
</runtime>
</configuration>
Odkryłem także, że source
EDIT: Oryginalny pytanie jest poniżej linii.
Korzystam z platformy .NET 4.0 Framework iz moich badań wiem, że zestaw System.Threading.Tasks nie jest już potrzebny (ponieważ jest dołączany automatycznie). Czy nie mam racji co do tego?
Jeśli mam rację, jestem teraz całkiem pewien, że błąd został zgłoszony, ponieważ wersja System.Threading.Tasks używana przez twórców klienta google-api-dotnet-client i używana przez Visual Studio 2010 to: różne.
Zauważyłem to podczas sprawdzania zachowania aplikacji po usunięciu niektórych linii.
I te linie wyszło:
gcal = new CalendarService(new BaseClientService.Initializer()
{
Authenticator = auth,
ApplicationName = APP_NAME,
});
Więc moje nowe pytanie brzmi:
Is there a way to force the usage of one specific version of a reference assembly in VS2010 ?
Dziękuję za pomoc, jestem pewien, że to pomoże wielu ludzi, ponieważ w google- calendar-api-v3 jest źle udokumentowany.
Pozdrawiam, Bruno.
Mój problem polega na tym, że nie mogę uzyskać dostępu do interfejsu API Google jako usługi za pośrednictwem VisualStudio.
otrzymuję ten błąd:

I don” t zrozumieć, dlaczego mam wyjątek FileLoadException w zestawie System.Threading.Tasks. Próbuję dodać nową funkcjonalność do aplikacji, która już używa zadań bez problemów. Ta aplikacja używa obiektów TabPage, które działają w różnych wątkach.
Wygląda na to, że masz problem z asemblowaniem. –
Dzięki, bardzo mi to pomogło. –
