F# vs. C# Compile Times

compile-times.md

This covers the build times of the core projects of https://github.com/aspnetde/IUBH.TOR:

• CS: https://github.com/aspnetde/IUBH.TOR/tree/master/src/cs/IUBH.TOR/IUBH.TOR
• FS: https://github.com/aspnetde/IUBH.TOR/tree/master/src/fs/IUBH.TOR/IUBH.TOR

Note that both cover the exact same functionality.

Compiling the F# core project with

<PropertyGroup>
  <OtherFlags>--sig:Signatures.fsi</OtherFlags>
</PropertyGroup>

results in a signature file that cannot be compiled:
