XAF: Deployment

Blazor App Deployment

IIS

<!-- web.config (auto-generated on publish) -->
<system.webServer>
  <aspNetCore processPath="dotnet"
              arguments=".\MyApp.dll"
              stdoutLogEnabled="false"
              stdoutLogFile=".\logs\stdout"
              hostingModel="inprocess">
    <environmentVariables>
      <environmentVariable name="ASPNETCORE_ENVIRONMENT" value="Production" />
    </environmentVariables>
  </aspNetCore>
</system.webServer>

Steps:

1. Publish: dotnet publish -c Release -o ./publish
2. Create IIS App Pool → .NET CLR version: No Managed Code, Pipeline: Integrated
3. Set physical path to publish folder
4. Install ASP.NET Core Hosting Bundle
5. Ensure ASPNETCORE_ENVIRONMENT=Production in IIS env vars

Azure App Service

# Publish from CLI
dotnet publish -c Release -o ./publish
az webapp deploy --resource-group MyRG --name MyXafApp --src-path ./publish

Connection strings in Azure App Service:

Set via Portal → App Service → Configuration → Connection strings (or Environment Variables):

ConnectionStrings__Default=Server=myserver.database.windows.net;Database=MyDb;User Id=...;Password=...;

Or in appsettings.Production.json:

{
  "ConnectionStrings": {
    "Default": "Server=myserver.database.windows.net;Database=MyDb;..."
  }
}

DevExpress license in Azure:

DEVEXPRESS_LICENSE_KEY=<your-license-key>

(Set as Application Setting in Azure Portal)

Docker

FROM mcr.microsoft.com/dotnet/aspnet:8.0 AS base
WORKDIR /app
EXPOSE 8080

FROM mcr.microsoft.com/dotnet/sdk:8.0 AS build

WinForms Deployment

ClickOnce

<!-- In .csproj -->
<PublishUrl>publish\</PublishUrl>
<Install>true</Install>
<ApplicationVersion>1.0.0.*</ApplicationVersion>
<BootstrapperEnabled>true</BootstrapperEnabled>

dotnet publish -c Release /p:PublishProfile=ClickOnce

MSI Installer (WiX / Visual Studio Setup Project)

1. Add Setup Project to solution
2. Add project output of WinForms project
3. Add prerequisites: .NET Runtime, DevExpress redistributables
4. Build → produces .msi

Database Initialization

Auto-migration on startup (Development)

// In WinApplication / BlazorApplication
DatabaseUpdateMode = DatabaseUpdateMode.UpdateDatabaseAlways;

Production — controlled migration

// Handle DatabaseVersionMismatch to control when migration runs
application.DatabaseVersionMismatch += (s, e) => {
    if (IsProductionSafeToMigrate()) {
        e.Updater.Update();
        e.Handled = true;
    }
    else {
        MessageBox.Show("Database requires migration. Contact administrator.");
        e.Handled = true;
    }
};

EF Core — run migrations on startup

// In Program.cs (Blazor) before app.Run():
using (var scope = app.Services.CreateScope()) {
    var factory = scope.ServiceProvider.GetRequiredService<IDbContextFactory<ApplicationDbContext>>();
    using var ctx = factory.CreateDbContext();
    ctx.Database.Migrate();
}

---

Connection Strings

appsettings.json (EF Core)

{
  "ConnectionStrings": {
    "Default": "Server=(localdb)\\mssqllocaldb;Database=MyApp;Trusted_Connection=True;"
  }
}

appsettings.json (XPO)

{
  "ConnectionStrings": {
    "Default": "XpoProvider=MSSqlServer;data source=(localdb)\\mssqllocaldb;initial catalog=MyApp;integrated security=True;"
  }
}

Multiple environments

// appsettings.Development.json
{ "ConnectionStrings": { "Default": "Server=(localdb)..." } }

// appsettings.Production.json
{ "ConnectionStrings": { "Default": "Server=prod-server..." } }

Set environment: ASPNETCORE_ENVIRONMENT=Production (env var or launchSettings.json)

---

DevExpress License Deployment

# Environment variable (recommended for CI/CD and containers)
DEVEXPRESS_LICENSE_KEY=your-devexpress-license-key

# Or file-based: %APPDATA%\DevExpress\license.key (Windows)
# Or: ~/.config/DevExpress/license.key (Linux/macOS)

Get your license key from DevExpress Customer Center.

In CI/CD (GitHub Actions example):

env:
  DEVEXPRESS_LICENSE_KEY: ${{ secrets.DEVEXPRESS_LICENSE_KEY }}

---

Logging (Serilog)

// Install: Serilog.AspNetCore, Serilog.Sinks.File, Serilog.Sinks.Console

builder.Host.UseSerilog((ctx, lc) => lc
    .WriteTo.Console()
    .WriteTo.File("logs/xaf-.log", rollingInterval: RollingInterval.Day)
    .ReadFrom.Configuration(ctx.Configuration));

// XAF uses ILogger<T> internally — logs to Serilog automatically
// Log from your own code:
public class MyController : ViewController {
    readonly ILogger<MyController> _logger;
    [ActivatorUtilitiesConstructor]
    public MyController(ILogger<MyController> logger) : base() {
        _logger = logger;
    }

    protected override void OnActivated() {
        base.OnActivated();
        _logger.LogInformation("Controller activated for view {ViewId}", View?.Id);
    }
}

---

ASP.NET Health Checks

// Add health checks
builder.Services.AddHealthChecks()
    .AddDbContextCheck<ApplicationDbContext>("database")
    .AddCheck("xaf", () => {
        // Custom XAF health check
        return HealthCheckResult.Healthy("XAF running");
    });

// Map health check endpoint
app.MapHealthChecks("/health");
app.MapHealthChecks("/health/ready", new HealthCheckOptions {
    Predicate = check => check.Tags.Contains("ready")
});
