By default, EBPF programs will not run on WSL2 due to required kernel modules missing. The following example error is an 
indication of this problem:
  modprobe: ERROR: ../libkmod/libkmod.c:586 kmod_search_moddep() could not open moddep file '/lib/modules/4.19.84-microso
  ft-standard/modules.dep.bin'
  modprobe: FATAL: Module kheaders not found in directory /lib/modules/4.19.84-microsoft-standard
  chdir(/lib/modules/4.19.84-microsoft-standard/build): No such file or directory

To fix this you need to rebuild the WSL2 kernel with the missing kernel modules. The below instructions are for Ubuntu 18.04 WSL2.

1. git clone https://github.com/microsoft/WSL2-Linux-Kernel.git

Comparison of ASP.NET and Node.js for Backend Programming

We will compare ASP.NET and Node.js for backend programming.
Source codes from examples.

Updates

This document was published on 21.09.2015 for a freelance employer. Some changes since then (14.02.2016):

1. Koa.js no longer uses co-routines, it has switched to Babel's async/await. yield and await are used almost in the same way, so I see no point to rewrite the examples.
