From Zero to Hero: Minimal APIs in .NET with C#

Front row seats at the future of ASP.NET Core APIs

When Minimal APIs were launched with the release of .NET 6, they allowed us to build scalable and fast APIs in .NET in ways that weren't possible before. Not only do they simplify the approach of building APIs and make them more accessible than ever, but they bring an incredible performance boost to the table. Microsoft has gone on record saying that they expect most new .NET APIs to be built using Minimal APIs for a good reason. They are a robust solution that allows developers to express themselves and create the system they need exactly how they want it. So don't miss your chance to master this topic right after its launch.
