Version 3: When Equals assembly is unused build fails with an exception

[Bruno Juchli]

When performing a build immediately after adding Equals.Fody 3.0.1 to a project, the build fails with:

Error: Fody: An unhandled exception occurred:
Exception:
Failed to execute weaver C:\Users\BRUNO.lorenz.juchli.nuget\packages\equals.fody\3.0.1\build..\weaver\Equals.Fody.dll
Type:
System.Exception
StackTrace:

Source:
FodyIsolated
TargetSite:
Void ExecuteWeavers()

Type:
System.InvalidOperationException
StackTrace:

The exception occurs when trying to resolve the [assembly reference to "Equals"}(https://github.com/Fody/Equals/blob/master/Equals.Fody/ReferenceFinder.cs#L53).

Minimal Repro

See #104.
Alternatively:

• Create new Project
• Add Fody
• Add Equals.Fody
• Build

[Bruno Juchli]

Workaround

• put an [Equals] attribute on a type
• remove Equals.Fody from the project as long as you don't use it (don't forget to adapt FodyWeavers.xml accordingly, too)
