Design Time Visual Studio options

Setting Comments
Visual Studio Modeless This option is applicable only if you select Visual Studio 2017 or Visual Studio 2019 to develop scripts.

In most cases, you should leave this check box selected. This minimizes the Edit Script in Visual Studio dialog box and makes it modeless. As soon as you click Save in the Visual Studio IDE, the changes to your script are copied to the Windows client cache and marked as modified. In addition, you can exit Design Mode and still access the Visual Studio instance from Runtime mode.

Clear this check box to enable the modal interface and enforce modal dialog access to Visual Studio. In this case, you can only edit scripts while you are in Design Mode.
