This article mainly introduces the relevant knowledge of the ASP net core interview questions, the content is detailed and easy to understand, the operation is simple and fast, and it has a certain reference value. I believe you will gain something after reading this ASP net core interview questions. Let's take a look at it.

Question 1: what is ASP net core?

First of all, ASP net core is not an upgraded version of asp net. It follows the standard architecture of dot net and can run on multiple operating systems. It is faster, easier to configure, more modular, and more scalable.

Question 2: what are the good functions of asp dot core?

The first is dependency injection.

The second is the log system architecture.

The third is the introduction of a cross-platform network server, kestrel. Apache and nginx can be run separately without iis.

Fourth, you can use the command line to create applications.

The fifth is to configure the project using APP settings json file.

The sixth is to use start up to register the service.

The seventh is better support for asynchronous programming.

The eighth is to support web socket and signal IR.

The ninth is the prevention and protection mechanism for cross-site requests.

Question 3: what are the advantages of dot net core compared with dot net?

The first is cross-platform, which can run on three major operating systems, windows, Linux and MAC.

The second is that there is no dependency on the installation of the architecture itself, because all dependencies are with the program itself.

The third is that dot net core processes requests more efficiently and can handle more requests.

The fourth is that dot net core has more installation and configuration methods.

Question 4: what is meta packages?

Meta packages is a package that contains all ASP dot net code dependencies. It's called Microsoft.AspNetCore.

Question 5: can don net core applications work with the dot net 4.x architecture?

Sure. Dot net core applications can work with standard dot net libraries.

Question 6: what is dot net core's startup class?

Startup class is the entrance to dot net core applications. All dot net core applications must have this class class to configure the application.

The call to this class is configured in the program main function. The name of the class can be defined by itself.

Question 7: what is the use of Startup class's config service method?

In this method, we can add some service into the dependency injection container.

Question 8: what is the use of startup class's configure method?

This method defines how the entire application responds to HTTP requests. It has several important parameters, application builder,Hosting environment, logo factory, where we can configure some middleware to handle paths, validation, session, and so on.

Question 9: what is middleware?

Middleware here refers to the components that are injected into the application to process requests and responses.

Question 10: what is the difference between application builder's use and run methods?

Both of these methods are called in the configure method of start up class. Are used to add middleware to the application request pipeline. The Use method can call the addition of the next middleware, but run will not.

Question 11: what is the role of map expansion in the dot net core pipeline?

You can add different middleware for different paths.

Question 12: how to deal with the paths in dot net core?

Path handling is a mechanism used to find handlers for incoming requests. All paths are registered at the beginning of the function run.

There are mainly two kinds of path processing, conventional path processing and attribute path processing. The conventional path processing is to set the call path in the way of MapRoute, and the attribute path processing is to set a path attribute above the calling function.

Question 13: how to activate the session function in dot net core?

The first step is to add the session package. The second step is to add session to the config service method. Then call usesession in the configure method.

Question 14: how many engineering documents are there in the dot net core project?

Global, launch setting,app settings,bundle config,bower, package .

Question 15: what is tag helper in dot net core?

Tag helper is used to create html elements on the server side using the Razor view engine.

Question 16: how to invalidate tag helper at the element level?

Use an exclamation point.

Question 17: what is a Razor page?

Is a development model that supports ASP web page tables in dot net core. @ page is used as the starting flag of the page.

Question 18: how to implement data model binding in Razor pages?

Use the bindproperty property.

Question 19: how to inject service into controller?

Configure the service in the config services method.

In the constructor of controller, add this dependency injection.

Question 20: describe the service life cycle after dependency injection?
