Catalog Information

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.
