Lamar is designed as a direct replacement; start by swapping the NuGet package and updating namespaces. Many APIs are similar but improved—refer to the documentation website for specific migration guides and breaking changes.

Question 2

Lamar vs .NET Core built-in DI which one should I use?

Accepted Answer

Use Lamar for higher performance and advanced features like method injection in complex applications. For simpler projects, .NET Core's built-in DI is more integrated and sufficient, saving setup time.

Accepted Answer

Yes, Lamar integrates seamlessly with ASP.NET Core via its service collection. Configure it in the Startup class to replace the default DI container for better performance and flexible dependency management.

Question 4

What are the performance benefits of Lamar over Autofac?

Accepted Answer

Lamar is optimized for speed and low overhead, often outperforming Autofac in dependency resolution benchmarks. It reduces memory usage and accelerates instance creation, making it ideal for high-throughput .NET applications.

Question 5

How to handle object lifetimes in Lamar?

Accepted Answer

Lamar provides flexible lifecycle management through scopes like Transient, Singleton, and Scoped. Configure lifetimes in the registry or at registration time to control instance creation and disposal based on application needs.

Question 6

Is Lamar free to use in commercial projects?

Accepted Answer

Yes, Lamar is open source under the MIT license, so it's free for commercial use. However, JasperFx offers paid support plans for additional assistance, which might be necessary for enterprise-level deployments.
