Implementing API versioning API versioning enables multiple versions of your API to coexist, allowing clients to migrate gradually. Common ways to version APIs in ASP.NET Core: ● URL versioning (e.g., /api/v1/products) ● Query string versioning (e.g., /api/products?

api-version=1.0)

• Header versioning (custom header like api-version: 1.0)
• Media type versioning (via Accept header, e.g., application/json;v=1)

Use the Microsoft.AspNetCore.Mvc.Versioning NuGet package:

services.AddApiVersioning(options => {

options.AssumeDefaultVersionWhenUnspecified = true;

options.DefaultApiVersion = new ApiVersion(1, 0);

options.ReportApiVersions = true;

});
