In this commodity series, we are activity to actualize a web appliance appliance ASP.NET Amount 2.0 and Angular 5 with the advice of Entity Framework Core’s database aboriginal approach. We will be creating a sample Agent Almanac Management system. To apprehend the inputs from the user, we are appliance Angular Forms with appropriate acreage validations on the applicant side. We are additionally activity to bind a dropdown account in the Angular Form to a table in the database appliance EF Core.
We will be appliance Visual Studio 2017 and SQL Server 2012.
Before proceeding I would acclaim you to get the antecedent cipher from GitHub.
We will be appliance two tables to abundance our data.
Execute the afterward commands to actualize both tables:
Now, we will put some abstracts into the tblCities table. We will be appliance this table to bind a dropdown account in our web appliance from which the adapted burghal can be selected. Use the afterward admit statements.
Now, our database allotment has been completed. So, we will advance to actualize the MVC appliance appliance Visual Studio 2017.
Open Visual Studio and baddest Book >> New >> Project.
After selecting the project, a “New Project” chat will open. Baddest .NET Amount central Visual C# card from the larboard panel.
Then, baddest “ASP.NET Amount Web Application” from the accessible activity types. Set the name of the activity as EFNgApp and columnist OK.
After beat on OK, a new chat will accessible allurement you to baddest the activity template. You can beam two drop-down airheaded at the top larboard of the arrangement window. Baddest “.NET Core” and “ASP.NET Amount 2.0” from these dropdowns. Then, baddest “Angular” arrangement and columnist OK.
Now, our activity will be created. You can beam the binder anatomy in Solution Explorer as apparent in the beneath image.
Here, we accept our Controllers and Views folders. We won’t be affecting the Views folders for this tutorial back we will be appliance Angular to handle the UI. The Controllers folders will accommodate our Web API controller. The point of absorption for us is the ClientApp binder area the applicant ancillary of our appliance resides. Central the ClientApp/app/components folder, we already accept a few apparatus created which are provided by absence with the Angular arrangement in VS 2017. These apparatus won’t affect our application, but for the account of this tutorial, we will annul fetchdata and adverse folders from ClientApp/app/components.
We are appliance Entity Framework amount database aboriginal access to actualize our models. Navigate to Accoutrement >> NuGet Amalgamation Manager >> Amalgamation Manager Console.
We accept to install the amalgamation for the database provider that we are targeting which is SQL Server in this case. Hence, run the afterward command:
Since we are appliance Entity Framework Accoutrement to actualize a archetypal from the absolute database, we will install the accoutrement amalgamation as well. Hence, run the afterward command:
After you accept installed both the packages, we will arch our archetypal from the database tables appliance the afterward command:
Do not balloon to put your own affiliation cord (inside ” “). After this command gets accomplished successfully, you will see that a Models binder has been created and it contains three chic files myTestDBContext.cs, TblCities.cs, and TblEmployee.cs. And appropriately we accept auspiciously created our Models appliance EF amount database aboriginal approach.
Now, we will actualize one added chic book to handle database accompanying operations.
Right bang on Models binder and baddest Add >> Class. Name your chic EmployeeDataAccessLayer.csand bang Add on. At this point in time, the Models binder will accept the afterward structure.
Open EmployeeDataAccessLayer.cs and put the afterward cipher to handle database operations.
Now, we will advance to actualize our Web API Controller.
Right bang on Controllers binder and baddest Add >> New Item.
An “Add New Item” chat box will open. Baddest ASP.NET from the larboard panel, again baddest “Web API Ambassador Class” from the templates console and set the name as EmployeeController.cs. Columnist OK.
This will actualize our Web API EmployeeController class. We will put all our business argumentation in this controller. We will alarm the methods of EmployeeDataAccessLayer to back abstracts and canyon on the abstracts to the Angular frontend.
Open the EmployeeController.cs book and put the afterward cipher into it.
We are done with our backend logic. So, we will now advance to cipher our frontend appliance Angular 5.
Tune in aing tomorrow to body the front-end of our application!
