Visual Studio Marketplace Version Visual Studio Marketplace Installs Nuget Nuget

A simple yet organized project template for building ASP.NET Core APIs using .NET Core 3.x (the latest/fastest version of .NET Core to date) with preconfigured tools and frameworks. It features most of the functionalities that an API will have such as database CRUD operations, Token-based Authorization, Http Response format consistency, Global exception handling, Logging, Http Request rate limiting, HealthChecks and many more. The goal is to help you get up to speed when setting up the core structure of your app and its dependencies when spinning up a new ASP.NET Core API project. This enables you to focus on implementing business specific code requirements without you having to copy and paste the core structure of your project, common features, and installing its dependencies all over again. This will speed up your development time while enforcing standard project structure with its dependencies and configurations for all your apps.

If you are looking for a project template for ASP.NET Core API that you can reuse across your team, or if you are new to ASP.NET Core and would like to get up to speed on how it works without having you to configure most of the basic features that an API will have, then this is for you.

How To Get It?

There are two ways to install the template:

Tools and Frameworks Used

Keep in mind that you can always replace and choose whatever framework you want to use for your API. After all, the template is just a skeleton for your project structure with default preconfigured middlewares. For example, you can always replace Dapper with Entity Framework Core, PetaPoco, etc. and configure them yourself. You can also replace Serilog with whatever logging frameworks and providers you want that works with ASP.NET Core - the choice is yours.

Key Takeaways

Here's the list of the good stuff that you can get when using the template:

  • Configured Sample Code for database CRUD operations.
  • Configured Basic Data Access using Dapper.
  • Configured Logging using Serilog.
  • Configured AutoMapper for mapping entity models to DTOs.
  • Configured FluentValidation for DTO validations.
  • Configured AutoWrapper for handling request Exceptions and consistent HTTP response format.
  • Configured AutoWrapper.Server for unwrapping the Result attribute from AutoWrapper's ApiResponse output.
  • Configured Swagger API Documentation.
  • Configured CORS.
  • Configured JWT Authorization and Validation
  • Configured Sample Code for Requesting Client Credentials Token
  • Configured Swagger to secure API documentation with Bearer Authorization.
  • Configured Sample Code for connecting Protected External APIs.
  • Configured Sample Code for implementing custom API Pagination.
  • Configured HttpClient Resilience and Transient fault-handling
  • Configured Http Request Rate Limiter
  • Configured HealthChecks and HealthChecksUI
  • Configured Unit Test Project
  • [Deprecated] Configured Sample Code for Worker service. For handling extensive process in the background, you may want to look at the Worker Template created by Jude Daryl Clarino. The template was also based on ApiBoilerPlate.

Install the Template from .NET CLI

  1. Install the latest .NET Core SDK.
  2. Run dotnet new -i apiboilerplate.aspnetcore. This will install the template in your machine.
  3. Run dotnet new apiboilerplate --name "MyAPI" -o samples. This will generate the project template named MyAPI within the samples directory.

Once installed, you should see the following console message:

The template "ASP.NET Core API Template for .NET Core 3.x" was created successfully.

Install the Template from Visual Studio Marketplace

Note: If you are using the previous version of the template, make sure to uninstall it first before you install the latest version.

  1. Fire up Visual Studio 2019, click Continue without code link.
  2. On the Extensions menu, click Manage Extensions.
  3. Click Online and then search for ApiBoilerPlate.
  4. Click Download. The extension is then scheduled for install.

To complete the installation, close all instances of Visual Studio.

Alternatively, you can download and install the VSIX Extension directly at the following link:

Create a new Project from ApiBoilerPlate Extension

  1. Open Visual Studio 2019 and then select Create New Project box
  2. The newly installed template should appear at the top. You can also type "ApiBoilerPlate" in the search bar.
  3. Click the ApiBoilerPlate item and then click Next.
  4. Name your project to whatever you like and then click Create.
  5. Visual Studio should generate the files for you.

Steps to Run the Template

STEP 1: Create a Test local Database:

  1. Open Visual Studio 2019
  2. Go to View > SQL Server Object Explorer
  3. Drilldown to SQL Server > (localdb)\MSSQLLocalDB
  4. Right-click "Database" Folder
  5. Click "Add New Database"
  6. Name it as "TestDB" and click OK
  7. Right-click on the "TestDB" database and then select "New Query"
  8. Run the script below to generate the "Person" table.
CREATE TABLE [dbo].[Person]
    	[FirstName] NVARCHAR(20) NOT NULL, 
    	[LastName] NVARCHAR(20) NOT NULL, 
    	[DateOfBirth] DATETIME NOT NULL

STEP 2: Update Database ConnectionString (Optional)

If you follow step 1, then you can skip this step and run the application right away.

If you have a different database and table name then you need to change the connectionString in appsettings.json that is pointing to the newly created database. You can get the connectionString values in the properties window of the "TestDB" database in Visual Studio.
