C# ASP.NET Core Middleware filter Middleware
This post is about a new feature in ASP.NET MVC, Middleware filter. Middleware typically sits in the global request handling pipeline. If you want to apply middleware to a specific controller or action method, you can use this feature. This feature only available with ASP.NET Core MVC 1.1. Long back I created a middleware (HTML Minification Middleware), which helps to minify generated HTML of an action. After few days I got a request to implement configuration options, which helps to exclude certain actions from minification. Now I can use Middleware filters instead of configuring the options.
To use middleware as a filter you first create a type with a
Configure method that specifies the middleware pipeline that you want to use. I am not sure about the naming conventions, I just followed the one provided by Microsoft.
Now you can use this type in specific controller class or action methods like this.
MiddlewareFilter attribute is only available, if you are using ASP.NET Core MVC 1.1.
You can find more features and details about ASP.NET Core 1.1 Preview 1 release here
Happy Programming :)
