Implementing API versioning?

Q: Implementing API versioning?

Short answer: API versioning enables multiple versions of your API to coexist, allowing clients to migrate gradually. Explain a bit more 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; Example code options.DefaultApiVersion = new ApiVersion(1, 0); options.ReportApiVersions = true; }); Say this in the interview Define — one clear sentence (the short answer above). Example — relate it to a project like ShopNest or your real work. Trade-off — when you would not use it.

Example code

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