Add versioning to .NET 10 minimal API using Asp.Versioning.Http

Authorised Territory demonstrates how to add API versioning to a .NET 10 Minimal API using the Asp.Versioning.Http NuGet package.

Overview

The video shows how a Minimal API can expose two versions of the same endpoint using the Asp.Versioning libraries.

Add API versioning with Asp.Versioning.Http

• Uses the Asp.Versioning.Http NuGet package to enable versioning for ASP.NET Core Minimal APIs.
• Configures the API so that a single logical endpoint can be served under multiple versions.

Versioning strategies demonstrated

• Query parameter versioning
  • Clients pass the version number via a query string parameter.
• URL segment versioning
  • Clients pass the version number as part of the route (URL path segment).

Deprecate an API version

• Demonstrates how to mark a specific API version as deprecated, so consumers can be guided toward newer versions.

Testing in Visual Studio

• Uses a .http file in Visual Studio 2026 to send requests and validate behavior across versions.
