Tweetinvi authenticating in a universal windows 10 app

Question

I use the method Auth.SetUserCredentials(...);

When i try to authenticate in a test console app and publish a tweet everything is fine. When i do the same in a uwp app i get this error when trying to authenticate:

System.TypeInitializationException: The type initializer for 'Tweetinvi.Auth' threw an exception. ---> System.IO.FileLoadException: Could not load file or assembly 'System.Core, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040) at Tweetinvi.Core.TweetinviCoreModule.Initialize() at Tweetinvi.Injectinvi.AutofacContainer.InitializeModules()

Answer 1

I was having the same issue. I found a post that said to use the command Install-Package tweetinviapi -version 0.9.10.2-w10-uap -pre

This stopped the error happening and now the app appears as though it should have posted, no error, but nothing is posted to Twitter.

Answer 2

I have same issue in UWP. I downgrade TweetinviApi from Nuget to version 0.9.10 and this work for me.
