HttpContext.Current is null on TokenCache.BeforeAccess about active-directory-dotnet-webapp-webapi-openidconnect

I was not able to get it to work so i stopped using session and is now using HttpRuntime.Cache. I basically just replaced HttpContext.Current.Session[CacheId] with HttpRuntime.Cache[CacheId]. Seems to be working well.

Found the cause. ADAL add configureAwait(false) for all async method starting from version 3.13.0, which results to HttpContext.Current in NaiveSession becomes NULL because it is most likely in a new thread. You can use 3.12.0 version of ADAL which works fine.

Using HttpRuntime.Cache seems a better solution which doesn't have such thread issue. Thanks ttctilsted for sharing!
