We can also register logging and set minimium loglevel as shown below. It also overrides loglevel configured in appsetting. SetMinimumLevel LogLevel. What is Startup file? Now the question is, is startup. Yes, startup. Multiple Startup classes are allowed in a single application.
NET Core will select the appropriate class based on its enviroment. Should we need to define class name with startup. No, it is not necessary, that class name should be Startup. We can define two methods in startup file like ConfigureServices and Configure along with constructor.
When any request comes to the application, he ConfigureService method will be called first. ConfigureServices method includes IServiceCollection parameter to register services. This method must be declared with a public access modifier, so that environment will be able to read the content from metadata. This method is mostly used for registering middleware in HTTP pipeline. Once we add some service in ConfigureService method, it will be available to Configure method to be used.
UseMvc is know as middlware. Middleware is new concept introduce with Asp. UseHttpsRedirection ; app. UseStaticFiles ; app. UseRouting ; app. It is a shorthand way of adding middleware to the pipeline that does not call any other middleware which is next to it and immediately returns HTTP response. NET Core web application is actually a console project which starts executing from the entry point public static void Main in Program class where we can create a host for the web application.
As you can see above, the Main method calls method expression BuildWebHost to build web host with pre-configured defaults. The following is CreateDefaultBuilder method. Kestrel is an open-source, cross-platform web server for ASP. NET Core. It is designed to be used behind proxy because it has not yet matured to be exposed as a full-fledge web server.
It also calls ConfigureAppConfiguration to load configurations from appsettings. The ConfigureLogging method setup logging to console and debug window. C ASP. Skill Tests ASP. Bundling and minification are two techniques you can use in ASP. NET 4. Bundling and minification improves load time by reducing the number of requests to the server and reducing the size of requested assets such as CSS and JavaScript.
What is routing in MVC? Routing is a mechanism in MVC that decides which action method of a controller class to execute. Without routing there's no way an action method can be mapped.
What is the use of bundle config in MVC? Bundling and Minification provide us a way to both reduce the number of requests needed to get JS and CSS resource files and reduce the size of the files themselves, thereby improving the responsiveness of our apps.
They are nice little optimizations for our MVC apps that can improve performance and add responsiveness. Where is BundleConfig CS? Use Styles. Render " bundle name" method to include style bundles in a razor view. What is scaffolding in MVC? JS etc. Further you can edit or customize this auto generated code according to your need. What is partial view in MVC? Partial view in ASP. It is just like a user control of a web form application. Partial can be reusable in multiple views.
It helps us to reduce code duplication. In other word a partial view enables us to render a view within the parent view. How does bundling work in MVC?
