Quick Start

Console / Desktop App

cd examples/ConsoleApp
# Edit Program.cs with your credentials
dotnet run

Works for any desktop scenario: console apps, WPF, WinForms, or .NET MAUI. Use LicenseManagerClient directly.

ASP.NET Core Web API

cd examples/AspNetCoreApi
# Edit appsettings.json with your credentials
dotnet run

Endpoints:

Method	URL	Description
GET	/license/connection	Test server connectivity
POST	/license/activate	Activate a license
GET	/license/verify/{productId}	Verify current license
POST	/license/deactivate/{productId}	Deactivate license
POST	/license/update-check	Check for updates
GET	/license/latest/{productId}	Get latest version
POST	/license/update-download	Download update file

Blazor Server

cd examples/BlazorServer
# Edit appsettings.json with your credentials
dotnet run

Opens an interactive dashboard at https://localhost:5001 with forms for activation, verification, and update checking.

Using the Client Library

The shared LicenseManagerClient class in src/ can be used in any .NET project:

using LicenseManager;

var options = new LicenseManagerOptions
{
    ServerUrl = "https://your-license-server.com",
    ApiKey = "your-api-key",
    ApplicationUrl = "https://your-app.com",
};

using var client = new LicenseManagerClient(options);

// Activate
var result = await client.ActivateLicenseAsync("PRODUCT_ID", "LICENSE-CODE", "Client Name");
if (result.IsActive)
    Console.WriteLine("Licensed!");

// Verify (uses saved license file)
var verify = await client.VerifyLicenseAsync("PRODUCT_ID");

// Check for updates
var update = await client.CheckForUpdateAsync("PRODUCT_ID", "1.0.0");
if (update.UpdateAvailable)
    Console.WriteLine($"New version: {update.Version}");
