## Content
This topic demonstrates how to create a Web API service application using Visual Studio template in Visual Studio.
### WebAPI Core 3.0
1. Open Visual Studio 2019 and select **Create a new project**.
2. In the **Create a new project** window, select Web project type and then select ASP.NET Core Web Application template.
3. Specify the Project name and Location and then click on Create.
4. Select the .NET Core version as ASP.NET Core 3.0 and the project type as API from the template wizard and then click on Create to setup the WebApi application.
5. Add the C1 WebApi references to the project. In the Solution Explorer, right click Dependencies and select Manage NuGet Packages. In NuGet Package Manager, select **https://api.nuget.org/v3/index.json** as the Package source. Search for **C1.AspNetCore.Api** package, and click **Install**.
6. To use specific services in your application, add the following NuGet Packages based on the service.
| **Service** | **Assembly (Location - C:\\Program Files (x86)\\ComponentOne\\Packages)** |
| --- | --- |
| Barcode | C1.AspNetCore.Api.Barcode |
| Cloud | C1.AspNetCore.Api.Cloud |
| Excel | C1.AspNetCore.Api.Excel |
| Data Engine | C1.AspNetCore.Api.DataEngine |
| Visitor | C1.AspNetCore.Api.Visitor |
