## LicenseChecker Class

Manages and enforces licensing constraints on clients and issuers within the application, ensuring compliance
with defined licensing terms\.

```csharp
public static class LicenseChecker
```

Inheritance [System\.Object](https://learn.microsoft.com/en-us/dotnet/api/system.object 'System\.Object') → LicenseChecker

### Remarks
This class dynamically validates the number of clients and issuers against the licensing terms,
logging warnings or errors when the application
operates beyond these constraints\. It supports real\-time updates to the license,
allowing the application to adjust to new licenses dynamically\.
