WebGL build renames referenced DLL file to .exe and then cannot find it with the old .dll name

IL2CPP

-

Reproduction steps:
1. Open the user's attached project "Edgar-Repro.zip"
2. Build the project for the WebGL platform

Expected result: The project is successfully built
Actual result: The project is not built and an error is displayed

Reproducible with: 2018.4.36f1, 2019.4.26f1, 2020.3.10f1, 2021.1.7f1, 2021.2.0a18

Notes:
-The error messages are different with newer Unity versions
-The error says that Unity cannot find the EdgarSingleFile.dll in the StagingArea folder and it should be like that, however, there's a file called EdgarSingleFile.exe. It might be that Unity evaluated that the ILMerged EdgarSingleFile.dll is actually an EXE file and copied the file with a wrong extension to the StagingArea.
-There are no issues when building for PC

  1. Resolution Note (2020.3.X):

    This behavior is by design: IL2CPP writes a file with a main() function because the "EdgarSingleFile.dll" is actually marked as an executable in its metadata.

    Since this DLL was created with ILMerge, it was probably created with the wrong "TargetKind". In order to work with IL2CPP correctly, the DLL should be created as a ILMerge.Kind.Dll with the command line option for ILMerge: "/target:library"
