This week it&rsquo;s C#. .NET has had everything the spec needs in the box for a decade, and since .NET 8 it has had Native AOT, which compiles the whole program to a single native executable with no runtime to install. I wanted to know whether that gets a C# client anywhere near Go on size and cold start. It gets closer than I expected, though the runtime column on the leaderboard shows what the binary size leaves out.</p>
