I am using below code to fetch AAD token using 3.16 version of ADAL library on .DOTNET core 2.0 and consistently getting TaskCancelledException after 1 min. Even on retries this is happening.
var authenticationContext = new AuthenticationContext(auth);
if (authenticationContext == null)
throw (new ArgumentNullException("AuthenticationContext")); authenticationContext.TokenCache.Clear();
ClientAssertionCertificate clientAssertion = new ClientAssertionCertificate(clientId, certificate);
AuthenticationResult authenticationResult = authenticationContext.AcquireTokenAsync(audience, clientAssertion).Result;
