## Usage

```c#

public class ConstraintException : laget.Exceptions.Exception

{

    public override HttpStatusCode StatusCode => HttpStatusCode.MethodNotAllowed;

    public ConstraintException(string message)

        : base(message)

    {

    }

    public ConstraintException(string message, Exception ex)

        : base(message, ex)

    {

    }

}

```

### Middleware

```c#

public class ExceptionMiddleware

{

    readonly RequestDelegate _next;

    public ExceptionMiddleware(RequestDelegate next)

    {

        _next = next;

    }

    public async Task Invoke(HttpContext context)

    {

        try

        {

            await _next(context);

        }

        catch (laget.Exceptions.Exception ex)

        {

            await HandleExceptionAsync(context, ex);

        }

        catch (Exception e)

        {

            if (e.InnerException?.GetBaseException() is laget.Exceptions.Exception)

            {

                await HandleExceptionAsync(context, e.InnerException?.GetBaseException() as laget.Exceptions.Exception);

            }

            await HandleExceptionAsync(context, e);

        }

    }

    static Task HandleExceptionAsync(HttpContext context, Exception ex)

    {

        return HandleExceptionAsync(context, ex.GetResponse());

    }

    static Task HandleExceptionAsync(HttpContext context, laget.Exceptions.Exception ex)

    {

        return HandleExceptionAsync(context, ex.GetResponse());

    }

    static Task HandleExceptionAsync(HttpContext context, laget.Exceptions.Models.Response model)

    {

        context.Response.Clear();

        context.Response.ContentType = "application/problem+json";

        context.Response.StatusCode = model.Status ?? (int)HttpStatusCode.InternalServerError;

        var response = JsonConvert.SerializeObject(model);

        return context.Response.WriteAsync(response);

    }

}
