Question thirteen. What Is Asp.Internet Core?
ASP.NET Core is a modern day go-platform web framework constructed with .NET Core framework.
It isn't an update to current ASP.NET framework. It is a whole rewrite of the ASP.NET framework. It was built from scratch in the attempt to make a modular, scalable, first-rate speedy, configurable, cross-platform and without difficulty extended web framework.
ASP.NET Core (on Linux!) itself can cope with over 2 000 000 – 2 Million requests in line with 2nd for plaintext request/response scenarios. ASP.NET Core MVC can handle over 1 million requests in keeping with 2nd! Compared to Node.Js, that could deal with about four hundred 000 requests in step with 2d, this is an super attempt.
It works with each .NET Core and .NET Framework.
ASP.NET Core is much purifier and less complicated to paintings with. You best want to write down 20~30 traces of code and you've the web server geared up to run. It additionally works easily along with your document gadget, so can just copy and paste documents on your task folder. And no, you don’t want to reference those documents from a .Csproj record.
Main characterestics of ASP.NET Core:
DI Container that's pretty easy and integrated. You can make bigger it with different famous DI packing containers
Built-in and extensible dependent logging. You can redirect output to as many assets as you want (file, Azure, AWS, console)
Extensible strongly typed configuration, which can also be used to reload at run-time
Kestrel – new, cross-platform and incredible speedy internet server which can stand by myself without IIS, Nginx or Apache
New, completely async pipeline. It is without problems configured through middleware
ASP.NET All meta bundle which improves development pace, and permits you to reference all Microsoft packages for ASP.NET Core and it's going to set up handiest the ones which are being used by your code
There is not any net.Config. We now use appsettings.Json file in combination with different sources of configuration (command line args, surroundings variables, and so forth.)
There is no Global.Asax – We have Startup.Cs that is used to set up Middleware and offerings for DI Container.

Question 16. Dependency Injection In Asp.Net Core?
Dependency Injection comes as part of ASP.NET Core Framework and the whole thing is built round it. When you need to use some tool and its offerings, you typically upload the NuGet package deal and you use certainly one of its extension techniques to add the bundle to the ASP.NET Core’s DI box. You can extend the present day DI with a container of your preference (AutoFac, StructureMap, CastleWindsor and many others).
Question 17. The Configuration In Asp.Internet Core?
Another essential part of ASP.NET Core Framework is Configuration. Also, it is part of Dependency Injection. Use it anywhere in your code with an option to reload on changes of configuration values from assets (appsettings.Json, surroundings variables, command line arguments, and so on.). It is also easy to override, make bigger and customise the Configuration. No more vast configurations in net.Config, the favored way now is appsettings.Json in combination with a mixture of Environment variables and cmd-line args.

Question 19. Explain Startup Process In Asp.Internet Core?
Everything begins from Program.Cs
public static void Main(string args)
public static IWebHost BuildWebHost(string args) =>
CreateDefaultBuilder extension approach will create a default configuration to be able to appearance first into appsettings.Json files then will search for Environment variables and on the stop, it'll use command line arguments.
This element will also installation default logger assets (debug and console) and cargo the settings for logging from appsettings.Json.
After the CreateDefaultBuilder finishes, then Startup magnificence is carried out. First, the constructor code is accomplished. After that, offerings are added to DI box thru AddServices technique that lives in Startup magnificence. After that, an order of middleware so as to take care of every incoming request is installation.
Question 20. Talk About New .Csproj File?
.Csproj report is now used as a place wherein we control the NuGet packages for your application.
File explorer and assignment explorer at the moment are in sync. For .NET Core projects, you could without problems drop a document from report explorer into a undertaking or delete it from the document device and it will likely be long past from the task. No greater source files in a .Csproj document.
You can now edit the .Csproj file at once without unloading the project.

Question 21. What Is Razor Pages?
Razor Pages is a new characteristic of ASP.NET Core that makes coding web page-targeted scenarios easier and more productive.
With Razor Pages, you have got this one Razor report (.Cshtml), and the code for a unmarried web page lives interior of that record, and that record additionally represents the URL structure of the app (greater approximately this later). Therefore, you got everything interior of 1 report, and it just works.
However, you CAN separate your code to the code behind document with .Cshtml.Cs extension. You would generally have your view model and handlers (like motion methods in MVC) in that file and cope with the logic there. Of path, you may additionally have your view model moved to split location.
Since Razor Pages is a part of the MVC stack, you may use something that incorporates MVC inner of our Razor Pages.
Question 22. What About Static Files In Asp.Internet Core (mvc)?
All static files are now (by means of default) positioned inside of wwwroot folder. You shop your CSS, JS, snap shots, fonts and others static content inner of it.
Question 23. What Is Startup.Cs In Asp.Internet Core?
In ASP.NET, Global.Asax acts because the access point to your software.
In ASP.Internet Core,startup.Cs is the access point on your utility.
In Startup.Cs document
The constructor hundreds the AppSettings.Json document the usage of ConfigurationBuilder elegance
The ConfigureServices() method adds the offerings required by using the application. For instance, here you add MVC and Entity Framework to the offerings series.
The Configure() approach specifies and configures the services brought in advance for application’s use.

Question 25. Differences Between .Net Core And .Internet Framework?
The variations among the two may be summarized in these 3 points:
NuGet-based: .NET Core is shipped as a set of NuGet packages that permit app-local deployments. In comparison, the .NET Framework is continually hooked up in a system-extensive vicinity. This difference doesn’t be counted a lot for class libraries; however it matters for packages as the ones are anticipated to install the closure of their dependencies. But we assume this version to alternate how quickly class library authors can take gain of latest functionality. Since the programs can in reality installation a new edition (in preference to having to attend till a given .NET Framework version is widely adopted), there is much less of a penalty for factor authors to take advantage of the modern-day capabilities.
Well layered: .NET Core became specially designed to be layered. The aim become to create a .NET stack that may accommodate a huge form of skills and gadget constraints with out forcing customers to recompile their binaries and/or produce new belongings. This way that we needed to cast off positive APIs due to the fact they tied lower degree components to better level additives. In the ones instances, we offer alternatives, frequently inside the form of extension methods.
Free of elaborate tech: .NET Core doesn’t include certain technology we decided to discontinue because we found them to be problematic, as an example AppDomain and sandboxing. If the situation nonetheless makes experience for .NET Core, our plan is to have replacements. For instance, AssemblyLoadContext replaces AppDomains for loading and separating assemblies.
Question 26. Explain .Net Family Of Frameworks?
.NET Framework is the "full" or "traditional" flavor of .NET it truly is dispensed with Windows. Use this when you are building a computer Windows app or working with ASP.NET four.Five/four.6.
.NET Core is go-platform .NET which can run on Windows, Mac, and Linux. Use this when you need to construct programs which could run on any platform, including ASP.NET Core (cross-platform net programs).
Xamarin (Mono) is used for constructing mobile apps which can run on iOS, Android, or Windows Phone devices.
