There is almost always an open-source clone or alternative for .NET-based commercial software. Examples:
If you need a between Activator and Compiled Expressions .
This occurs if the constructor itself throws an error. Check the InnerException property to see the real cause of the failure.
Many .NET 4.6.1 applications have 30-day trials. Instead of using an activator to reset the clock constantly, use that time to evaluate if you truly need the software.
Most activators found on public forums or file-sharing sites are bundled with Trojan horses, miners, or ransomware . Since these tools require administrative privileges to modify system registry keys and bypass security checks, they provide a "front door" for attackers to take full control of the machine.
class Program { static void Main(string[] args) { // Case 1: Create using parameterless constructor Type serviceType = typeof(MyService); object obj = Activator.CreateInstance(serviceType); ((MyService)obj).Print(); // Output: Default
