Question 1

What method is used to add middleware to the ASP.NET Core request pipeline?

app.UseMiddleware<T>() is the standard method to add custom middleware to the ASP.NET Core pipeline.

Question 2

In what order does ASP.NET Core execute middleware components?

Accepted Answer

In the order they are registered

Answer

Middleware executes in the order it is registered in the Configure method or Program.cs.

Question 3

What does calling next() inside middleware do?

Accepted Answer

Passes control to the next middleware in the pipeline

Answer

Invoking next() passes the HttpContext to the subsequent middleware component in the pipeline.

Question 4

Which built-in middleware should be placed before routing middleware to serve static files?

Accepted Answer

UseStaticFiles

Answer

UseStaticFiles() should be called before UseRouting() so static files are served without going through routing.

Question 5

What is a short-circuiting middleware?

Accepted Answer

Middleware that does not call next(), ending the pipeline

Answer

A short-circuiting middleware returns a response without calling next(), preventing further middleware from executing.
