string.Format("function PageSpecificLoad() {{ ShowPanel('{0}'); }", pnlVoertuigPopup.Id)

The runtime will throw a System.FormatException (2nd '}' is missing at end of format string), while I expected R# to check string.Format strings on correctness. OK, I'm not sure to what extend R# does check the format string, but it does check on

• missing arguments
• superfluous arguments
• "non-existing argument" in case of e.g.

  string.Format("function PageSpecificLoad() { ShowPanel('{0}'); }", pnlVoertuigPopup.Id)

  That's why I thought that R# does check for correctness.

If this is no current functionality, you might see this as a feature request.
