Jitted code from plaintext, using CoreCLR chk jit at commit b10828cd81693debaca841028d251543d4497902
Source at https://github.com/aspnet/KestrelHttpServer/blob/dev/src/Microsoft.AspNetCore.Server.Kestrel/Internal/Http/FrameOfT.cs
Huge method (0x84c bytes of IL). Has a lot of EH and a lot of switches.
