Create the Project

Start a New Minimal API Project

Open rider and select New Solution

Enter CrudApp as the solution name

Enter CrudAppAPI as the project name

Choose the solution directory

Uncheck put solution and project in the same directory

Choose whether to create a Git repository

Select template Web API and press create

Open the Program.cs file and delete the comments, example endpoint along with its variable and record. You should then be left with a clean empty project

var builder = WebApplication.CreateBuilder(args);

builder.Services.AddOpenApi();

var app = builder.Build();

if (app.Environment.IsDevelopment())
{
    app.MapOpenApi();
}

app.UseHttpsRedirection();

app.Run();

Install the Required Nuget Packages

We will need to add nuget packages to use the methods required to connect to our SQL database. We will also use Dapper to simplify our database access and FluentValidation to validate incoming data.

Open the NuGet package manager and search for the following and add them to the project:

Dapper FluentValidation FluentValidation.AspNetCore FluentValidation.DependencyInjectionExtensions Microsoft.Data.SqlClient

Add a Connection String

To connect to our database, we will need to add a connection string with the required details.

Add the connection string to the appsettings.Development.json file

{
  "ConnectionStrings": {
    "DefaultConnection": "Server=localhost,1433;Database=CrudApp;User Id=sa;Password=Password123;TrustServerCertificate=True;"
  },
  "Logging": {
    "LogLevel": {
      "Default": "Information",
      "Microsoft.AspNetCore": "Warning"
    }
  }
}
