Mid ASP.NET Core

Using middleware for logging or performance (e.g. measuring?

execution time)

Example custom middleware to measure time:

public class TimingMiddleware

private readonly RequestDelegate _next;

public TimingMiddleware(RequestDelegate next) => _next =

next;

public async Task InvokeAsync(HttpContext context)

var sw = Stopwatch.StartNew();

await _next(context);

sw.Stop();

Console.WriteLine($"Request took

{sw.ElapsedMilliseconds} ms");

app.UseMiddleware<TimingMiddleware>();
