How can I implement API versioning in ASP.NET Core using query strings?

You can implement API versioning in ASP.NET Core by using the Microsoft.AspNetCore.Mvc.Versioning package. First, install the package via NuGet. Then, in your Startup.cs, configure the services to use versioning with query strings.

What does the configuration in Startup.cs look like?

In Startup.cs, you can add the following code in the ConfigureServices method:

services.AddApiVersioning(options =>
{
    options.ReportApiVersions = true;
    options.AssumeDefaultVersionWhenUnspecified = true;
    options.DefaultApiVersion = new ApiVersion(1, 0);
    options.ApiVersionReader = new QueryStringApiVersionReader("v");
});

How do I specify the version in the query string when making a request?

You can specify the version in the query string by appending ?v=1.0 to your API endpoint. For example, https://yourapi.com/products?v=1.0.

Can I use other methods for versioning as well?

Yes, ASP.NET Core supports various versioning methods, including URL segments, headers, and media types. You can choose the one that best fits your needs.
