MSBuild Error

SOLUTION:
No need to use Fody for something like this. Simply embed the DLL as a resource in your .csproj, and then load the resource on runtime. It’s a lot more complex than it sounds without Visual Studios.

I heard Fody.Costura is able to add reference assemblies as resources. Seen at pardeike/Harmony#234. In this case, I am trying to embed the Lib.Harmony.dll into my main .DLL file.

Please check all of the platforms you are having the issue on (if platform is not listed, it is not supported)

  • WPF
  • UWP
  • iOS
  • Android
  • .NET Standard
  • .NET Core 6.0

Version of Library

v5.7.0 (Latest)

Version of OS(s) listed above with issue

Windows 10

Steps to Reproduce

  1. Install Fody
dotnet add package Fody
  1. Install Costura.Fody
dotnet add package Costura.Fody
  1. Include an Assembly into FodyWeavers.xml (or don't, it's the same)
<?xml version="1.0" encoding="utf-8"?>
<Weavers xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="FodyWeavers.xsd">
    <Costura IncludeAssemblies="0Harmony" />
</Weavers>
  1. Build the .DLL
dotnet build SomeMod

Expected Behavior

Build succeeded.

What sort of project is SomeMode and what sort of library is the Harmony lib (managed, unmanged, etc)?

@GeertvanHorrik No idea what managed or unmanaged means, but according to this forum, I am guessing it is managed.

I am not sure what to tell you about SomeMod. It's a DLL that'll be injected into a Mono program?

Might be useful to show my .csproj here.

This is an unsupported target framework. Also not marking the Lib.Harmony as private assets defeats the purpose of Costura.

I think it's important to understand managed vs. unmanaged first since it makes a huge difference on how to use Costura. Please read more here

Also please note that Costura is in maintenance mode and getting support is not very likely.
