Catalog Information

For detailed information on each license option, choose the license type using the buttons below.

For developers who need to build deployable applications.

One development license is required for each development seat.

For multiple developers, consider Team Edition licensing.

Projects built with a Full Development license generate an embedded runtime license which is embedded into your executable assembly.

The embedded runtime license system eliminates the need for license activation steps on runtime PCs.

For developers and/or end users who need to build and/or run on a single PC.

Single Machine licenses cannot be used to build deployable applications.

Projects built with a Single Machine license do not generate an embedded runtime license. Instead, ASComm.NET will look for a physical license file on the PC.
