Restrict client from using web application & DB on another machine

Hi Chirag,

One solution(using a Unique Key similar to your previous solution), is to create a console/desktop application that unlocks your installed MVC application.
Here is how it works :
1/Generate a Serial specific to PC/Server using the ManagementClass

public static String GetProcessorId()
  {

      ManagementClass mc = new ManagementClass("win32_processor");
      ManagementObjectCollection moc = mc.GetInstances();
      String Id = String.Empty;
      foreach (ManagementObject mo in moc)
      {

          Id = mo.Properties["processorID"].Value.ToString();
          break;
      }
      return Id;

  }

Now, this just get the processor_ID, you need somthing more viable.
You can get Manufacturer, Processor ID,Adress Mac ...
More informations about
Get Computer Hardware Information using C#[^]
After you create your own Serial generator.
2/You run your SerialGen (your console/desktop app) in Target Machine, and save it in DB, file...

3/In your MVC Application_Start(), you generate the Serial and compare it to the one saved using your SerialGen.

*ofc, the serial will not work in any other machine since its related to the one it was genreated on.

Thats it.

This solution only works if you have access to the Target Machine.
Few years earlier, I used somthing similar but instead of running SerialGen in Target Machine, i send data using a service, and check if that Machine have a licence.

Hope it helps.

PS: You need to add a reference to System.Management.
Right click on References in solution explorer -> Add Reference.
On the .NET tab select System.Management and click OK.
