[UWP]Could not load assembley(badimageformatexception)

Question

Error to call any method of System.Threading , System.IO or System.ReflectionTypeExtensions that have been imported from nuguet in a universal app aplication, underneath have a exemple :

Call : private void Button_Click(object sender, RoutedEventArgs e) {

        var thread = Thread.CurrentThread;

    }

Error: Could not load file or assembly 'System.Threading.Thread, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. Reference assemblies should not be loaded for execution. They can only be loaded in the Reflection-only loader context. (Exception from HRESULT: 0x80131058)

Hi Marcelo,

This forum is discussing client application development using Windows Forms controls and features, your issue is more related with Universal apps, I will move this thread to the more related forum.

Thanks for your understanding.

Welcome to the Developing Universal Windows apps forum! 

Please read the sticky posts, especially the Guide to posting: subject line tags and Known Issues for Windows 10 SDK and Tools 

This is expected. Universal apps use the .NET for Windows Runtime apps, which does not include the classes and namespaces you mention. Instead you will use the Windows Runtime for similar (but generally async) behavior. For example, instead of using System.Threading.Thread you can spin up a worker thread with Windows.System.Threading.ThreadPool.
