Failed to load assembly when merging complete project

[devedse]

Hi all, I'm trying to merge a big set of the .NET Standard dll's into a WPF project. Previously this worked fine but after upgrading some thing to the latest .NET Core / .NET Standard I seem to get the following exception:

The PowerShell file I'm using to build: https://github.com/devedse/DeveImageOptimizerWPF/blob/master/Scripts/GoRepack.ps1

The build failing on AppVeyor (it's marked green but it's actually failing): https://ci.appveyor.com/project/devedse/deveimageoptimizerwpf

I already tried changing the order and first passing netstandard.dll, but that didn't help either.

Hi,

I've never tried .Net Core/Standard, but got feedback that it worked fine. Though ILRepack may need some hints about where to find the referenced libraries, did you try adding /lib:PATH_TO_NETSTD_FOLDER ?

(PR welcome to implement these hints in ILRepack, currently it only knows where to find the .Net Framework assemblies)

[lextm]

Similar to other Mono Cecil based projects, as the user you need to manually specify which folder to locate the dependencies for .NET Standard 2.0 based assemblies.

See if /lib:"c:\Program Files\dotnet\sdk\NuGetFallbackFolder\microsoft.netcore.app\2.0.0\ref\netcoreapp2.0\" helps.

Encountering the same issue on Myget for netstandard2.0 ILRepack. Hinting didn't appear to work.

I just tried it using the latest NuGet package: 2.0.14 and suddenly my build worked!! :smile:.

I'm running into a new issue though. When I download the artefact from my build I see the following error 😭 :

You can view my source and build script here: https://github.com/devedse/DeveImageOptimizerWPF

The build output here: https://ci.appveyor.com/project/devedse/deveimageoptimizerwpf/build/1.0.30

And the build artefact (that crashes) here: https://ci.appveyor.com/project/devedse/deveimageoptimizerwpf/build/1.0.30/artifacts

@devedse Which version did you use when you posted the first post in this issue? (I'm trying to see what fixed between then and your version)

[emysa341]

I have a following situation

• Projects A, B and C.
• projectA references projectB and projectB references projectC.
• In the same way, projectA implements an interface(projectB) from projectB and same interface(projectB) inherits an interface from projectC.
• After using ILRepack I get a final "Merged.dll" file without any errors (I have specified the libs path to all needed dll files and also .Net standard dll files).
• When I use this dll. I get an error if I use any types after including namespaces from projectC-> "The type "" is defined in an assembly that is not referenced. You must add a reference to assembly 'assemblyName, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null".
• In visual studio logs, the search path to resolve assemblies is looking ProjectC.dll. But the fact is I don't need ProjectC.dll since that was already merged by ILRepact to product a single DLL "Merged.sll". So it should look into "Merged.sll" but for me thats not the case. I am using ILRepacking fromcake build in mono. Any Suggestions ?
• I have used ILSpy tool to decompile "Merged.dll" file. I can see reference of projectC in this dll. Also I can see the namespaces and public interface from projectC.

@timotei, that was on 2.0.13

[devedse]

With 2.0.16 I'm still running into this issue:

C:\XGitPrivate\DeveImageOptimizerWPF\Scripts\Output>DeveImageOptimizerWPF.exe

Unhandled Exception: System.BadImageFormatException: Duplicate type with name 'System.Data.AcceptRejectRule' in assembly 'DeveImageOptimizerWPF, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'.

I tried to add things like /union and /allowduplicateresources but this didn't work either. I got these from here; https://github.com/gluck/il-repack/issues/231

The strange thing is though that they don't appear in my ILRepack arguments either:

(It just shows the out:... parameter and all input files)

When doing a merge using the latest beta (v2.1.0-beta1) it does seem to include the /union parameter at the beginning, I get a lot more errors:

(Basically this error: https://github.com/gluck/il-repack/issues/181)

[devedse]

I also tried running ILMerge version ilmerge Version 2.14.1208 with the same command. This didn't give any errors and seemed to work. So for now I'll use ILMerge :).

https://github.com/Microsoft/ILMerge https://www.nuget.org/packages/ilmerge

The exe file generated by ILMerge opened in ILSpy: As can be seen, there are no duplicates here.

[Alexx999]

@devedse this is fixed by #235 I just hope that @gluck will merge that sometime soon and release a new version :)

[devedse]

Ah very nice +1

[devedse]

Hey all, any progress on this? @gluck @Alexx999

[timotei]

@emysa341 Can you please open a separate bug report with that issue and with a reproducible sample if possible? Otherwise we'll miss it.

[Alexx999]

@devedse it's fixed in the master. As a stopgap solution, I've published avostres.ILRepack package with this fix and Cecil 0.10, also there's ILRepack.Lib.MSBuild package

[devedse]

@Alexx999, @gluck, I dont think there's any more activity on this repo. It seems Microsoft is pushing new releases now and then for ILMerge.

[timotei]

@devedse Actually, there is, just that @gluck didn't manage to get some time to merge some of the stuff :D

[Alexx999]

@devedse it's worth noting that ILMerge is not perfect either - it failed when merging my projects same as ILRepack when I was picking merge tool to use. Now I'm just OK with maintaining my own ILRepack fork and don't really care to check how ILMerge is doing :) Ideally, @gluck would just spin off ILRepack by giving someone commit rights, but I'm not sure if that is going to happen.

[devedse]

I'm not sure if @gluck is still working on this projects. I don't see any commits in the last 9 months, so indeed, it might help to just give someone else the ability to do commits.

[lextm]

Take a look at the network graph, https://github.com/gluck/il-repack/network and you will see some forks are still active.

An open source project can continue in an active fork, if someone claims he/she will take over the responsibilities.

[gluck]

Hi ! Indeed my focus has shifted to other (non .Net) projects, and I don't have much time/motivation for this one now. That being said I don't want to let down the community either, and if there's anything (non-time consuming) I can do, let me know. I won't do reviews or investigate issues, but I'll have no concern merging any PR that a couple of members would have reviewed/tested, or making (automated) releases (but I'm not sure the gradle toolchain will survive w/o some effort, which for some reason the .Net community is unlikely to help with :) ). Good luck.

[KirillOsenkov]

The latest version should be working fine.
