In this article, we are going to discuss the Folder Structure Of ASP.NET Core MVC 6 . 0 application. In the previous post, we have created an ASP.NET Core MVC 6.0 project. Here is the link.
Let’s Get started:
1: Open the project:
Go to your folder in which you have created your project and double-click on the solution file. Now the project is opened and you can see the folders in solution explorer.

Now let’s understand the folder structure.
2: Open “.csproj” file:
Right-click on your project file and select “Edit Project” to open “.csproj” file.

After clicking on this you can see this code. First of all, in this file, you can see the project SDK. This project is using “Microsoft.NET.Sdk.Web”. After this, properties have been defined by the project in the <PropertyGroup> tag. In the <PropertyGroup> we can see the <TargetFramework> tag that has the .NET version of the project. The <Nullable> tag can be enabled and disabled with this property project nullable reference types can be handled. In the <RootNamespace> we have our project name. In <ItemGroup> we have <PackageReference> tag you can understand by its name its have our installed package reference. I have included “Microsoft.EntityFrameworkCore” in this package to my project so now our project has the reference to it.
<Project Sdk="Microsoft.NET.Sdk.Web"> <PropertyGroup> <TargetFramework>net6.0</TargetFramework> <Nullable>enable</Nullable> <ImplicitUsings>enable</ImplicitUsings> <RootNamespace>aspnet_core_mvc_6._0_demo_mycodebit</RootNamespace> </PropertyGroup> <ItemGroup> <PackageReference Include="Microsoft.EntityFrameworkCore" Version="6.0.1" /> </ItemGroup> </Project>
3: Connected Services:

This connected services have all the services of connected Azure or cloud databases. We can configure azure or cloud services using this section.
4: Dependencies:

In the dependencies folder, we have all the libraries, packages, and projects on which our project depends.
5: launchsetting.Json file:

In the Properties folder we have the launchsetting.Json file. As you can see in this JSON file we have mainly application URL and port settings. We can set the environment variable in this file that is commonly used in every application.
{ "iisSettings": { "windowsAuthentication": false, "anonymousAuthentication": true, "iisExpress": { "applicationUrl": "http://localhost:50150", "sslPort": 44375 } }, "profiles": { "aspnet_core_mvc_6._0_demo_mycodebit": { "commandName": "Project", "dotnetRunMessages": true, "launchBrowser": true, "applicationUrl": "https://localhost:7228;http://localhost:5228", "environmentVariables": { "ASPNETCORE_ENVIRONMENT": "Development" } }, "IIS Express": { "commandName": "IISExpress", "launchBrowser": true, "environmentVariables": { "ASPNETCORE_ENVIRONMENT": "Development" } } } }
6: wwwroot:

In the wwwroot folder, we have all the static files of our project like CSS, JavaScript, and other static libraries. You can see the subfolders for CSS, JavaScript, and other libraries.
7: Controllers:

In the controller’s folder, we have .cs files and these controllers have all the business logic of the application. The models and views don’t directly interact with each other.
8: Models:

In the Models folder, we have data classes and view classes that we use to show data in UI. We can add multiple ViewModels and database classes in this as per our project demand.
9: Views:

In the views folder, we have .cshtml files that are used for the User interface. We can change our application’s front end by changing the code in our views (.cshtml) files.
10: appsettings.json file

When you click on the appsettings.json file you will see the JSON code as I mentioned below. We can configure the database connection string in this file and also can set logging in the project.
{ "Logging": { "LogLevel": { "Default": "Information", "Microsoft.AspNetCore": "Warning" } }, "AllowedHosts": "*" }
11: Program.cs file

Our applications are based on the program.cs file because this file has the run and host configurations of our project. We can configure the Service of our project that we use with IServices interfaces in our program.cs file.
Organizing ASP.NET Core MVC 6.0 Application Structure
When building an ASP.NET Core MVC 6.0 application, it’s essential to organize your files and folders in a way that makes it easy to maintain and scale your project. In this section, we’ll discuss the best practices for organizing your application structure and customizing it based on your project’s requirements.
Understanding the Default Application Structure
Before we dive into how to organize your application structure, let’s first take a look at the default file structure of an ASP.NET Core MVC 6.0 application. By default, the application structure includes folders such as Controllers, Views, and Models, among others. These folders contain files that define your application’s behavior, views, and data models.
Best Practices for Organizing Your Application Structure
To ensure your project remains maintainable and scalable, it’s crucial to follow good organization practices. Here are some best practices for organizing your ASP.NET Core MVC 6.0 application structure:
- Group files and folders based on functionality: Group files and folders that are related to each other based on functionality. For example, you can group all controllers related to a specific module in a folder named after that module.
- Keep the structure simple: Avoid creating too many nested folders, as this can make it difficult to navigate and find files. Instead, keep the folder structure as flat as possible.
- Use meaningful and consistent naming conventions: Use clear and consistent naming conventions for folders and files. This can help make your code more readable and make it easier to find files.
- Separate static files from dynamic files: Separate static files, such as CSS and JavaScript, from dynamic files, such as views and controllers. This can help improve performance by reducing the number of requests to the server.
Customizing Your Application Structure
While the default application structure is a good starting point, you may need to customize it based on your project’s requirements. For example, you may need to add additional folders to separate your client-side code from your server-side code.
When customizing your application structure, it’s important to ensure that your changes do not affect the application’s behavior. Additionally, it’s a good idea to document any changes you make to the structure, so other developers can understand how the application is organized.
