C# Visual studio 2017 crash when custom user control throw exception

I am learning write my own user controls , and i find that when i throw exception during designer view, Visual studio 2017 will stop working.
I created a user control called "ColoredProgressBar" .
When AnimationStyle was set to ProgressBarAnimationStyle.Instantly and TextStyle was set ProgressBarTextStyle.AnimationPercentage then the class will throw a InvalidStyleCombinationException(this is my custom exception).
Here is my code :

private void Timer_Tick(object sender, EventArgs e)
{
    try
    {
        // . . . 
        if (this.AnimationStyle == SUPEXFunction.UI.ProgressBarAnimationStyle.Instantly && this.TextStyle == SUPEXFunction.UI.ProgressBarTextStyle.AnimationPercentage)
        {
            this.AnimationReachedValue = 0;
            InvalidStyleCombinationException a = new InvalidStyleCombinationException("ProgressBarAnimationStyle.Instantly and ProgressBarTextStyle.AnimationPercentage can't exist in same time .");
            throw a;
        }
        // . . . 
    }
    catch (Exception ex)
    {
        throw;
    }
}
public ColoredProgressBar()
{
    this.First = true;
    this.SetStyle(ControlStyles.UserPaint, true);
    this.timer.Interval = 1;
    this.timer.Start();
    this.timer.Tick += new EventHandler(Timer_Tick);
}

Is this a bug of VS 2017 ? How can i fix this without remove the exception ?

Your code has nothing to make VS 2017 to crash , No infinite loops nothing as I can see. Try updating your VS2017 with the latest update 2 days ago. It will work just fine.
