The licensing of load tests with C# test scripts is similar to the licensing model that applies when using BDL as scripting language. A single user run is always license-free. During a trial run, no license is being checked out. When executing a load test using C# scripts, Silk Performer checks for the technologies used in the scripts and maps them to equivalent feature license type web, standard, or premium. The mapping is the same as with BDL.

If however a C# script is used for .Net testing rather than driving one of the supported Silk Performer technologies, a standard license will be checked out.
