[severity:It bothers me. A fix would be nice]
In the following C# code, the Parameter Info feature does not work. And it stops working everywhere until restarting Visual Studio.

class C {
	void _Caller() {
		M(c: ); // To reproduce, click inside ( ) and press Ctrl+Shift+Space.
	}

/// <summary>
	/// About M.
	/// </summary>
	/// <param name="a">About a.</param>
	/// <param name="b">About b.</param>
	/// <param name="c">About c.</param>
	public static void M(int a = 0, int b = 0, int c = 0) { }
}
