Two blue arrows on desktop icon of installed assembly

The presence of two blue arrows on a desktop icon in Windows typically indicates that the icon is a shortcut to another location or file. This is Windows' way of indicating that the icon represents a link to another item rather than the actual item itself.

When you install certain applications or assemblies, they might create desktop shortcuts to easily access their executable files or other resources. These shortcuts are represented by icons with two blue arrows.

If you're seeing this on an installed assembly's desktop icon, it likely means that the icon is a shortcut to the actual assembly's executable or related file. Double-clicking the icon with the blue arrows should launch the associated application or assembly.
