It may be useful to know exactly
when this error happens: after you have just opened a Project/Solution when you first open the Form/UserControl in design-view, when your first click is on the TextBox ? On any TextBox ? Or, does it happen after the first time you run, or build, your project/solution ?
If you create a new WinForms Project, and drag-drop one TextBox onto the MainForm, and then click on it: does it crash every time you do this ?
You may also consider updating VS 2013 with the RC 4 update to see if that makes a difference: [

Unfortunately, knowing every detail of when/where the crash occurs may not prove helpful: I have an older computer with a 6420 CPU, and a newer one with an i5-4670k; both are running Win 8.1. On the old computer there are frequent crashes of Visual Studio 2013, on the new one they are very rare.
Consider filing a bug report with MS: [
^]. Note that I am about as optimistic that filing a bug with MS will result in a solution as I am that a letter to Santa will bring me what I want for Christmas :)
