Build a web API with .NET Core using CLI Tools
In this blog i will start with an introduction to .NET Core CLI tools with an example of how to create a web API using the CLI tools provided with .NET Core. At the end we will set up a solution grouping an API project and a test project. Let’s dive into the steps,
Step 1 : Installing the tools
dotnet new sln -o DotNetCoreDemoApi
The above command will create a new folder and DotNetCoreDemoApi a solution file with the name DotNetCoreDemoApi sln .
Step 3: Creating the web API project
Run the following command,
Now that the solution is here, we can create our API project. Lets name the web API as DotNetCoreDemoApi. Run the following command to create the project.
dotnet new webapi -o DotNetCoreDemoApi
That command will create a sub folder named DotNetCoreDemoApi inside the solution DotNetCoreDemoApi and the ouput is as follows.
The web API folder should contain a few files generated as above but what we require right now is DotNetCoreDemoApi.csproj. We will add a reference to it in our solution. To do so, run the following command:
dotnet sln add ./DotNetCoreDemoApi/DotNetCoreDemoApi.csproj
Step 4: Run the Web API
After getting a confirmation message as above , lets start the API by running that command:
dotnet run --project DotNetCoreDemoApi
After a few seconds, it should display a message that the API is now running locally as above. You may access it at http://localhost:5000/api/values which is the Values API default endpoint.
