## Pipeline Order
```
Request → Exception Handler → HSTS → HTTPS Redirect → Static Files
→ CORS → Authentication → Authorization → Custom Middleware → Endpoint
```
```csharp
var app = builder.Build();
// 1. Exception handling (first to catch all)
app.UseExceptionHandler("/error");
app.UseHsts();
// 2. HTTPS and static files
app.UseHttpsRedirection();
app.UseStaticFiles();
// 3. Routing
app.UseRouting();
// 4. CORS (before auth)
app.UseCors();
// 5. Auth
app.UseAuthentication();
app.UseAuthorization();
// 6. Custom middleware
app.UseMiddleware<RequestLoggingMiddleware>();
// 7. Endpoints
app.MapControllers();
```
## Custom Middleware (Convention-based)
```csharp
public class RequestLoggingMiddleware
{
private readonly RequestDelegate _next;
private readonly ILogger<RequestLoggingMiddleware> _logger;
public RequestLoggingMiddleware(RequestDelegate next, ILogger<RequestLoggingMiddleware> logger)
{
_next = next;
_logger = logger;
}
public async Task InvokeAsync(HttpContext context)
{
var sw = Stopwatch.StartNew();
_logger.LogInformation("Request {Method} {Path}", context.Request.Method, context.Request.Path);
await _next(context);
sw.Stop();
_logger.LogInformation("Response {StatusCode} in {Elap
