It's because we wish to make use of the Logger provider as a result of our software, such as the Tailor made Motion Filter, and we wish the Framework to inject the logger company through the constructor. So, include the following code to the Program.cs course file:
The subsequent sample exception filter displays particulars about exceptions that happen when the application is in growth:
If we produce some filters that comprise dependency, then we have to use that dependency with the assistance of dependency injection. You could implement your filter to a class or action methodology victimization just one in filters in asp.net mvc just about every of the next
