Overloads

Use(IApplicationBuilder, Func<HttpContext,RequestDelegate,Task>)

Adds a middleware delegate defined in-line to the application's request pipeline. If you aren't calling the next function, use Run(IApplicationBuilder, RequestDelegate) instead.
Use(IApplicationBuilder, Func<HttpContext,Func<Task>,Task>)

Adds a middleware delegate defined in-line to the application's request pipeline. If you aren't calling the next function, use Run(IApplicationBuilder, RequestDelegate) instead.

Prefer using Use(IApplicationBuilder, Func<HttpContext,RequestDelegate,Task>) for better performance as shown below: 

app.Use((context, next) =>
{
    return next(context);
});

Use(IApplicationBuilder, Func<HttpContext,RequestDelegate,Task>)

Source:
UseExtensions.cs
