Free ASP.NET Core 2.0 MVC Code Generator and Tutorial
ASP.NET Core, C#, Web Application, Visual Studio 2017, Web API, C#
AspCoreGen 2.0 MVC Express
is a free ASP.NET Core 2.0 MVC Code Generator software you can download absolutely free. AspCoreGen 2.0 MVC Express
generates a full solution with 2 projects; An ASP.NET Core 2.0 MVC Web Application project (main application - UI), and a .NET Core 2.0 Class Library Project (business tier, data tier, and shared libraries). The
optional ASP.NET Core 2.0 Web API project can only be generated using the Professional Plus Edition. It generates code by looking at your Microsoft SQL Server Database's tables.
The major objects generated are:
- Controllers (class)
- Middle-Tier code (class)
- Data Tier code (class)
- Models (class)
- View Models (class)
- Views (cshtml)
- Miscellaneous item (class)
Unlike the Professional Plus Edition, the Express Edition is limited. One of the main differences is the later will only generate Unbound Views, these
are MVC Views not bound to the database. In the page shown here
, there are 17 generated views, only
1 is generated by the Express Edition (#16, Unbound Views). Even with this limitation, the amount of code generated is absolutely outstanding. It can generate about a million lines of code in about
a minute depending on the amount of tables you have in the database, and it can do all this in One Click**.
Because the generated code is not connected to the database, this tutorial will show you how to add your own code to connect the generated MVC views to the database.
Now that I'm done with my marketing spiel let's get on with the tutorial.
You will need the following things for this tutorial:
- Microsoft Northwind Database (please Google it)
- Microsoft SQL Server 2003 and above
- You will need an Admin username/password or enough rights in the MS SQL Server. A blank username/password will not work.
- Visual Studio 2017 (the generated code will not work in Visual Studio 2015 and below)
- AspCoreGen 2.0 MVC Express
1. Download AspCoreGen 2.0 MVC Express here: https://junnark.com/Products/AspCoreGen2MVC/DownloadExpress
2. Install it. Just follow all the prompts. If you need a tutorial go here:
and click on the Installation Guide link.
3. Open AspCoreGen 2.0 MVC Express, go to the Database Settings
tab and enter the following information shown in the snapshot below. Note:
Use your database's username and password instead of the one's shown below. A blank password will not work.
4. Go to the Code Settings
tab and enter the Web Application Name
, and the Directory
where you want the generated code to be in. You can use the browse button next to the Directory
Box to choose the
directory where you want the code to be generated. You can keep the suggested Business Layer and Data Layer API
(Class Library Project) Name or change it, it's up to you.
5. Click the Generate Code for All Tables
or the Generate Code for Selected Tables Only
button. AspCoreGen 2.0 MVC Express will start generating code and you will see a message once code generation is done.
6. Close (or not) AspCoreGen 2.0 MVC Express. Go to the Directory
you specified and double-click the Solution file (.sln).
7. The solution will open in Visual Studio 2017. The Visual Studio Solution Explorer window shows 2 generated projects in the solution. Run the web application by pressing F5.
8. The home page shows all the major objects that was generated by AspCoreGen 2.0 MVC Express. The black bars represents the separate projects. Below each black bar are categories of
objects (blue bar) generated for that specific project. Clicking the blue bar will toggle visibility of the list of items for that category. Items under the Views Folder
are MVC Views (.cshtml) and are clickable to
demonstrate each MVC View's functionality.
9. Click on one of the web page links, e.g. the Products/Unbound
. You will notice that each field in the Products table are
shown here. Foreign keys are also shown as a Select List web control. There's also validation, for example Product Name here is a
required field. Note: AspCoreGen 2.0 MVC Express generates Unbound MVC Views, these are Views that are not bound to a database. Because these MVC Views are not bound to the database, you will notice that
the Select List for the Supplier ID and Category ID does not have data, and when you click Submit button nothing happens, it will not Insert or Update something in the database.
10. Close the web page and then go back to Visual Studio.
11. Since AspCoreGen 2.0 MVC Express does not generate code that binds web views to the database, let's bind the MVC View to the database by adding
logic to the ProductsControllerBase.cs
file under the Controller/Base
folder. Open the class ProductsExample.cs
under the CodeExamples
folder and then copy the code from
method to the ProductsControllerBase.cs's Unbound
Note: We will use a Layering approach (3-tier, n-tier), so, the Web View (Presentation Layer/Front End) will access the Products.cs
(Business Object), and then the Product.cs
will access the ProductsDataLayer.cs
(Data Layer) code. The Data Layer code would then access our database (MS SQL).
Products Example Class, Insert Method
Products Controller (Base Class) - Unbound IActionResult Method
12. Copy Insert Example code to the Controller Base's Unbound method as shown below.
13. Update the sample values to the Model
passed by the MVC View. Extract the Model
via the View Model
. The highlighted code
below accesses the Products's Insert
(Business Object) method. In short, the Controller accesses the Middle Layer (Business Object).
14. The Products's Insert
(Business Object) method accesses it's respective Data Layer method as shown in the highlighted code below.
15. Note that the Products's Insert
Data Layer method shown below has no code, just a code throwing a NotImplementedException error. This is one of the main difference with AspCoreGen 2.0 MVC Express and
Professional Edition, that's why Express generated MVC Views are not bound to a database.
16. Needless to say, you still need to add code in the ProductDataLayerBase.cs
Insert method which will insert the passed values to the database. Note:
Code below is
just an example.
Assign the Middle Tier values passed by the UI tier to whatever objects you have. Your objects could be an Entity Framework, or whatever you wish to
use that will interact with your database. Or you can just buy the AspCoreGen 2.0 MVC Professional Plus so that you don't even need to worry about the data layer, it should
generate this part as well as the respective Linq-to-Entities classes (EF Core), ore Stored Procedures, or Ad-Hoc SQL (sorry for the marketing spiel).
** One Click. As programmers we develop for one project until we're done or get pulled to another project. This means using the same database over and over again, adding more tables or
fields to existing tables and/or views, or updating them. The "One Click
" feature becomes really handy the next time you generate code for the same database, all you
have to do is click the Generate Code for All Tables
button when working on the same database, and that's it. AspCoreGen 2.0 MVC Express is absolutely free, no need to
register, no pop-ups asking you to buy the Professional Plus edition, no marketing/unsolicited emails whatsoever, yup - it's absolutely free.
