Hello,

Thank you very much for the assistance. I had tried registering the license prior to accessing as well, but was getting the same error. Also apologies on the mistyped namespace, that was misconfigured when I created the test project for you.

With that said, the solution was making the license file embeded! After doing so, I now see the license get registered correctly. Understood now that .net core requires the embeded resource for a license file.

Hello,

Thank you for assisting us on this. I have emailed This email address is being protected from spambots. You need JavaScript enabled to view it. with an example of the app and what we are seeing. Please let me know how else I can assist troubleshoot this issue.

Thank you!

We have a valid multipurpose license that I have installed on my machine. I have confirmed that the OPCLabs example code solutions can obtain the license serial number. This was confirmed in both .net and .net core code examples.

// Instantiate the client object.
var client = new EasyUAClient();
//Obtain the serial number from the license info.
long serialNumber = (uint)client.LicenseInfo["Multipurpose.SerialNumber"]

However, when I use these two lines of code in my UWP .net core solution, I always get the trial license serial number 1111111120. I have also tried manually registering the license using the recommended approach below, but it still isn't recognized ({namespace} was replaced with my namespace, but keeping the naming confidential here). Can you please help me with getting this working?

// The first two arguments should always be "QuickOPC" and "Multipurpose".
// The third argument determines the assembly where the license resides.
// The fourth argument is the namespace-qualified name of the managed resource.
OpcLabs.BaseLib.ComponentModel.LicensingManagement.Instance.RegisterManagedResource("QuickOPC", "Multipurpose",
System.Reflection.Assembly.GetExecutingAssembly(),
//"opclic.bin");
"{namespace}.Key-Permanent-ShareIt-1999523870-20201109.bin");


We are using the nuget package library. I have tried versions 5.59.1055 and version 5.61.343
