Cannot convert anonymous method to type 'System.Delegate' because it is not a delegate type

Question

I want to execute this code on main thread in WPF app and getting error I can\'t figure out what is wrong:

private void AddLog(string logItem)
        {

                


        

Answer 1

You can also use MethodInvoker for this:

private void AddLog(string logItem)
        {
            this.Dispatcher.BeginInvoke((MethodInvoker) delegate
            {
                this.Log.Add(new KeyValuePair(DateTime.Now.ToLongTimeString(), logItem));
            });
        }
