.NET Based OPC UA Client/Server SDK  3.0.10.493
Licensing the SDK

After purchasing the OPC UA .NET SDK you will receive your personal license file and a Release version of the SDK. To activate the license in your appliaction, you need to take the following steps:

  • add the license file to your project as an embedded resource;
  • use the current Release version of the UnifiedAutomation assemblies;
  • load your license file during start-up in the Main() function of the application (see example below).

In the following example, the name of the resource, “UnifiedAutomation.Sample.License.License.lic”, is composed of

  • the namespace “UnifiedAutomation.Sample”; remember to change this to the namespace used in your product;
  • the path to the license file “License.License.lic”; the license file (License.lic) is in our example located in an extra folder called “License”; remember to change this to your own folder structure.
static class Program
{
static void Main()
{
try
{
// applications without a UnifiedAutomation license embedded as a resource will stop working after 1 hour.
ApplicationLicenseManager.AddProcessLicenses(System.Reflection.Assembly.GetExecutingAssembly(), "UnifiedAutomation.Sample.License.License.lic");
ApplicationInstance.Default.Start();
}
catch (Exception e)
{
ExceptionDlg.Show(null, e);
return;
}
}
}
