This is Windows Forms application.

As in title, I can't debug Task in Visual Studio 2015. If I will check breakpoint at line `var a = costam();` it **will be** hit, but if then I will press step into, or continue, execution will not be continued. This works fine in Console Application. For now i checked, that error appears when I'am trying to run my own method in Task, or if I'am invoking something.

```
public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
        Task.Run(() =>
        {
            var a = costam();
        });
    }

    string costam()
    {
        return "s";
    }
}

```
