    How to log in ExceptionHandler ?

    Using Umbraco And Getting Started
    Umbraco 9

    Hi, i'm trying to add a exception handler wich will log the exception (in umbraco logs). How could this be done ? 

        public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
    {
        app.UseExceptionHandler(err => {
            app.Run(async context =>
            {
                // How can I log the error ?
            });
        });

    I have tried, without success, adding ILogger to Configure method parameters.

    Thank you

    Hi Alexandre,

    here's the official docs:

    https://our.umbraco.com/Documentation/Fundamentals/Code/Debugging/Logging/

    I think what you need to do is add the ILogger as a parameter in the constructor assign that to a private class variable which you can then access in the Configure method.

    You are right, the following constructor in Startup.cs works :

    public void Configure(IApplicationBuilder app, IWebHostEnvironment env, ILogger<Startup> logger)

    Thank you
