• Leo.Windows.App is a WinForms-based application.
• Leo.Wpf.App is a WPF-based application.
• Leo.Web.Host is a ASP.NET Core application.

NOTE: For simplify, the desktop application also launchs the Web API application in the same process.

NOTE: You can see more information about how to launch both the Desktop application and a backend Web API service application in one process at Leo.Windows.Program.Main and Leo.Wpf.App.App.

TIP: By default, the SQLite is used as the backend database. Here is the code snippet at src/Leo.Web.Api/Startup.cs:

namespace Leo.Web
{
    public class Startup
    {
        public void ConfigureServices(IServiceCollection services)
        {
            var dbEngine = Configuration.GetValue<string>("Database:Engine");
            if (string.Equals(dbEngine, "mssql", StringComparison.OrdinalIgnoreCase))
            {
                Leo.Web.Data.SqlServer.ServiceCollectionExtensions.AddDataServices(services);
            }
            else // "sqlite"
            {
                Leo.Web.Data.SQLite.ServiceCollectionExtensions.AddDataServices(services);
            }

The SQL Server migration scripts are located at src/Leo.Web.Data.SqlServer/SQL/Scripts/. You need to apply them manually.

When the application starts, it requires to login with a Microsoft account (an organization or personal account).

After login succeeded, we will enter the main window. On the main window, we can create an new customer or click the Find menu at the toolbar to find a and load a existed customer.
