.net core system.configuration.configurationmanager

JohnMoshakis · February 26, 2020, 10:34pm

Hi,

I have a .net core console app and I’ve added the nuget System.Configuration.ConfigurationManager.

At runtime I get

Unhandled exception. System.BadImageFormatException: Could not load file or assembly ‘System.Configuration.ConfigurationManager, Version=4.0.3.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51’. Reference assemblies should not be loaded for execution. They can only be loaded in the Reflection-only loader context. (0x80131058)
File name: ‘System.Configuration.ConfigurationManager, Version=4.0.3.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51’ —> System.BadImageFormatException: Cannot load a reference assembly for execution.
at ConsoleApplication6.Program.Main(String[] args)

I recall we saw this before with .net framework, I think the deps.json file from ebuild is wrong.

  "System.Configuration.ConfigurationManager/4.7.0": {
    "dependencies": {
      "System.Security.Cryptography.ProtectedData": "4.7.0",
      "System.Security.Permissions": "4.7.0"
    },
    "runtime": {
      "ref\\netstandard2.0\\System.Configuration.ConfigurationManager.dll": {
        "assemblyVersion": "4.0.3.0",
        "fileVersion": "4.700.19.56404"
      }
    }
  },

Its trying to pull in a file from the ref folder, which it shouldnt be doing.

Using visual studio I get this

  "System.Configuration.ConfigurationManager/4.7.0": {
    "dependencies": {
      "System.Security.Cryptography.ProtectedData": "4.7.0",
      "System.Security.Permissions": "4.7.0"
    },
    "runtime": {
      "lib/netstandard2.0/System.Configuration.ConfigurationManager.dll": {
        "assemblyVersion": "4.0.3.0",
        "fileVersion": "4.700.19.56404"
      }
    }
  },

Curious. I’ve had to tweak the ref vs lib thing several times now, because of inconsistencies. I’ll need to have a look at the concrete case, but unfortunately I’m out of the office most of the day today; I’ll check tomorrow. whats the exact versions of .NET Core you’re building with?

As a side note, \ vs / seems wrong too; will fix that as well.

To be clear, everything is fine for what is copy-located (System.Configuration.ConfigurationManager.dll is not copied next to the exe), the only issue is what’s in the .deps, correct?

JohnMoshakis · February 28, 2020, 1:06pm

I think so.

mh · February 28, 2020, 1:15pm

Does VC# copy-local the lib ref?

Because the current logic is (and changing intact is gonna break the 387 other issues we had with whit before) is that if a package resolves to not the exact target framework type (eg (. NET or .NET Core) but a common one (eg “.NET Standard”), we don’t copy-local or otherwise process the lib folder, and just use ref.

by comparison:

ref: /Users/mh/Library/Application Support/RemObjects Software/EBuild/Packages/NuGet/system.configuration.configurationmanager/4.7.0/ref/netstandard2.0/System.Configuration.ConfigurationManager.dll

ref: /Users/mh/Library/Application Support/RemObjects Software/EBuild/Packages/NuGet/system.security.permissions/4.7.0/ref/netcoreapp3.0/System.Security.Permissions.dll
lib: /Users/mh/Library/Application Support/RemObjects Software/EBuild/Packages/NuGet/system.security.permissions/4.7.0/lib/netcoreapp3.0/System.Security.Permissions.dll

system.security.permissions resolves to a .NET Core 3.0 version for lib and ref, so we copy-local it; but system.configuration.configurationmanager resolves to a. .NET Standard 2.0 one for ref and lib, so we ignore lib.

Changing that is gonna break whatever scenario I fixed for you 3 months ago.

I really wish there was any, you know, documentation or something silly like that, on how all this was supposed to be handled… :(.

JohnMoshakis · February 28, 2020, 1:24pm

No its not copied local

I was under the impression that should never copy local a ref or have it in the deps.json. ie only lib files are copied local or in the deps.json ? The ref is only for use in a build ?

JohnMoshakis · February 28, 2020, 1:36pm

I think this was the related issue

For .net framework the solution was to reference ref but only copy lib. So for core its reference ref but only us lib in the deps.json

mh · February 28, 2020, 1:39pm

Yeah, I co muted a potential fix that does just that, now.

that said, your snipped from VC# does have it in the deps.json…

JohnMoshakis · February 28, 2020, 2:21pm

The visual studio deps, runtime points to the lib ?

mh · February 28, 2020, 2:35pm

Right, but according to the copy local, it shouldn’t, because the file isn’t copy-local’ed.

JohnMoshakis · February 28, 2020, 4:35pm

I never noticed that visual studio doesnt havent a copy local for .net core ?

JohnMoshakis · February 28, 2020, 9:55pm

Did you mean to remove the runtime reference ?

Its changed from this

"System.Configuration.ConfigurationManager/4.7.0": {
    "dependencies": {
      "System.Security.Cryptography.ProtectedData": "4.7.0",
      "System.Security.Permissions": "4.7.0"
    },
    "runtime": {
      "ref\\netstandard2.0\\System.Configuration.ConfigurationManager.dll": {
        "assemblyVersion": "4.0.3.0",
        "fileVersion": "4.700.19.56404"
      }
    }
  },

to

      "System.Configuration.ConfigurationManager/4.7.0": {
        "dependencies": {
          "System.Security.Cryptography.ProtectedData": "4.7.0",
          "System.Security.Permissions": "4.7.0"
        },
        "compile": {
          "ref/netstandard2.0/System.Configuration.ConfigurationManager.dll": {
          }
        }
      },

mh · February 28, 2020, 10:13pm

Yes. That’s the fix I made. Sonde this is not copylocal (references from “ref” and the platform is not an exact match for “lib” – standard vs core), I’m not adding it to the deps.

JohnMoshakis · February 28, 2020, 10:15pm

I now get this

Unhandled exception. System.IO.FileNotFoundException: Could not load file or assembly ‘System.Configuration.ConfigurationManager, Version=4.0.3.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51’. The system cannot find the file specified.

:(.

Bloody fucking mess.

JohnMoshakis · February 28, 2020, 10:38pm

Yes.

If i create a 4.7.2 .net console and add the nuget it wont compile.

of course I cannot speak for whats inside that .dll or not. But it looks like for the .NET framework, System.Configuration.ConfigurationManager is inside the standard System.Configuration.dll dll thats in the framework, not in this NuGet package.

JohnMoshakis · February 29, 2020, 3:18pm

Yes I would just added system.configuration for a .net framework app, I just wanted to see what would happen if I added this nuget
