Creating REST endpoints using .NET Core Minimal API is a streamlined approach to building web APIs with less boilerplate code. Below is an example of how to create several REST endpoints using .NET Core Minimal API. This example assumes you are working with a simple model, such as a Product<\/code>, and provides endpoints for basic CRUD operations (Create, Read, Update, Delete).<\/p>\n\n\n\n

Step 1: Set Up the Project<\/h3>\n\n\n\n

First, create a new .NET Core Minimal API project:<\/p>\n\n\n\n

bashCopy codedotnet new web -n MinimalApiExample\ncd MinimalApiExample\n<\/code><\/pre>\n\n\n\n
Step 2: Define the Model<\/h3>\n\n\n\n
Create a simple Product<\/code> class that will represent the data:<\/p>\n\n\n\n
csharpCopy codepublic class Product\n{\n    public int Id { get; set; }\n    public string Name { get; set; }\n    public decimal Price { get; set; }\n}\n<\/code><\/pre>\n\n\n\n
Step 3: Set Up the In-Memory Data Store<\/h3>\n\n\n\n
For simplicity, we’ll use an in-memory list to store the products:<\/p>\n\n\n\n
csharpCopy codevar products = new List<Product>\n{\n    new Product { Id = 1, Name = \"Product 1\", Price = 10.00m },\n    new Product { Id = 2, Name = \"Product 2\", Price = 20.00m },\n    new Product { Id = 3, Name = \"Product 3\", Price = 30.00m }\n};\n<\/code><\/pre>\n\n\n\n
Step 4: Create the Minimal API Endpoints<\/h3>\n\n\n\n
In the Program.cs<\/code> file, define your Minimal API endpoints:<\/p>\n\n\n\n
csharpCopy codevar builder = WebApplication.CreateBuilder(args);\nvar app = builder.Build();\n\nvar products = new List<Product>\n{\n    new Product { Id = 1, Name = \"Product 1\", Price = 10.00m },\n    new Product { Id = 2, Name = \"Product 2\", Price = 20.00m },\n    new Product { Id = 3, Name = \"Product 3\", Price = 30.00m }\n};\n\n\/\/ Get all products\napp.MapGet(\"\/products\", () =>\n{\n    return Results.Ok(products);\n});\n\n\/\/ Get a product by ID\napp.MapGet(\"\/products\/{id:int}\", (int id) =>\n{\n    var product = products.FirstOrDefault(p => p.Id == id);\n    if (product is null)\n    {\n        return Results.NotFound();\n    }\n    return Results.Ok(product);\n});\n\n\/\/ Create a new product\napp.MapPost(\"\/products\", (Product product) =>\n{\n    product.Id = products.Max(p => p.Id) + 1;\n    products.Add(product);\n    return Results.Created($\"\/products\/{product.Id}\", product);\n});\n\n\/\/ Update an existing product\napp.MapPut(\"\/products\/{id:int}\", (int id, Product updatedProduct) =>\n{\n    var product = products.FirstOrDefault(p => p.Id == id);\n    if (product is null)\n    {\n        return Results.NotFound();\n    }\n\n    product.Name = updatedProduct.Name;\n    product.Price = updatedProduct.Price;\n\n    return Results.Ok(product);\n});\n\n\/\/ Delete a product\napp.MapDelete(\"\/products\/{id:int}\", (int id) =>\n{\n    var product = products.FirstOrDefault(p => p.Id == id);\n    if (product is null)\n    {\n        return Results.NotFound();\n    }\n\n    products.Remove(product);\n    return Results.NoContent();\n});\n\napp.Run();\n<\/code><\/pre>\n\n\n\n
Step 5: Run the Application<\/h3>\n\n\n\n
To run the application, use the following command:<\/p>\n\n\n\n
bashCopy codedotnet run\n<\/code><\/pre>\n\n\n\n
Step 6: Test the Endpoints<\/h3>\n\n\n\n
You can test the endpoints using tools like curl<\/code>, Postman, or directly in a browser.<\/p>\n\n\n\n
    \n
  1. Get all products<\/strong>:httpCopy codeGET \/products<\/code><\/li>\n\n\n\n
  2. Get a product by ID<\/strong>:httpCopy codeGET \/products\/1<\/code><\/li>\n\n\n\n
  3. Create a new product<\/strong>:httpCopy codePOST \/products Content-Type: application\/json { \"name\": \"New Product\", \"price\": 15.50 }<\/code><\/li>\n\n\n\n
  4. Update an existing product<\/strong>:httpCopy codePUT \/products\/1 Content-Type: application\/json { \"name\": \"Updated Product\", \"price\": 12.00 }<\/code><\/li>\n\n\n\n
  5. Delete a product<\/strong>:httpCopy codeDELETE \/products\/1<\/code><\/li>\n<\/ol>\n\n\n\n
