Can't publish C# DLL on .NETCore

[jplgarcia]

Steps to reproduce:

• DllExport -version: 1.7.3
• Used Visual Studio 2019

Information from Data tab or log data:

Every time I try to publish my DLL by right clicking and hitting publish I set target to my local folder configuration release, target framework .netcoreapp3.0 target runtime win-x64

The build and rebuild work fine but whenI publish I receive the following message " Publishing has encountered an error. Publishing has failed

A Diagnostic log has been written to the following location: "c:\User.....\AppData\Local\Temp\filename.tmp" "

Checking the file I receive an error that does not help very much:

2020-0

8-24 1:20:00 PM System.AggregateException: One or more errors occurred. ---> System.Exception: Publishing failed. --- End of inner exception stack trace --- at System.Threading.Tasks.Task.ThrowIfExceptional(Boolean includeTaskCanceledExceptions) at System.Threading.Tasks.Task.Wait(Int32 millisecondsTimeout, CancellationToken cancellationToken) at Microsoft.Publish.Framework.Model.DefaultPublishSteps.<>c__DisplayClass26_0.b2() at System.Threading.Tasks.Task`1.InnerInvoke() at System.Threading.Tasks.Task.Execute() --- End of stack trace from previous location where exception was thrown --- at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at Microsoft.Publish.Framework.Model.DefaultPublishSteps.d23.MoveNext() --- End of stack trace from previous location where exception was thrown --- at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at Microsoft.Publish.Framework.ViewModel.ProfileSelectorViewModel.d__202.MoveNext() ---> (Inner Exception #0) System.Exception: Publishing failed.<---

System.Exception: Publishing failed.

===================

My code is no more than the following class:

using System; using System.Runtime.InteropServices;

namespace ClassLibrary2 { public class Class1 { [DllExport("Add2", CallingConvention.Cdecl)] public static int testAdd(int a, int b) { return a + b; }

    [DllExport("Say2", CallingConvention.Cdecl)]
    public static void sayWhatever()
    {
        Console.WriteLine("it workss");
    }
}

}

Please follow our issue template and attach full information from the Data tab.

But I think you're just trying combine mentioned win-x64 runtime for x86+x64 configuration, that's incorrect. Check this out and reconfigure for x64.

Did you handle the issue like describe here https://github.com/dotnet/runtime/issues/33590 ?

Seems for .NET Core dll injection is not supported anymore.

Hi!

I have the exact same issue publishing a simple DllExport project targeted for .NET Core 3.1.

• DllExport version: v1.7.3.58831+9a4bc51
• Used Visual Studio 2019 16.8.2
• Target platform: x86
• Runtime identifier: win-x86

I've created simple .NET Core Class Library project, added most recent DllExport package from NuGet, configured the project for x86 (using workaround from #175) and when trying to publish the project, I get the same issue as stated above with the following error in the Output log:

Build started...
1>------ Build started: Project: DllExportTest, Configuration: Release x86 ------
1>DllExportTest -> [...]\DllExportTest\bin\x86\Release\netcoreapp3.1\win-x86\DllExportTest.dll
2>------ Publish started: Project: DllExportTest, Configuration: Release x86 ------
2>Determining projects to restore...
2>Restored [...]\DllExportTest\DllExportTest.csproj (in 291 ms).
2>DllExportTest -> [...]\DllExportTest\bin\x86\Release\netcoreapp3.1\win-x86\DllExportTest.dll
2>The file '[...]\DllExportTest\bin\x86\Release\netcoreapp3.1\win-x86\DllExportTest.pdb' to be packed was not found on disk.
========== Build: 1 succeeded, 0 failed, 0 up-to-date, 0 skipped ==========
========== Publish: 0 succeeded, 1 failed, 0 skipped ==========

Project builds without any issue but publish fails every time, tried also changing parameters with no luck.

I'm attaching the whole sample project if it helps. DllExportTest.zip

Thanks! ✌

Not sure what happened, but .NET Core version does not work properly. Manual conversion via NDDE works, but it generates separate unmanaged dll.

@supermartzin,

... pdb to be packed was not found on disk.

Your problem seems a bit different comparing this issue. Could you please open a new one. Thanks!

@mikasoukhov,

Seems for .NET Core dll injection is not supported anymore.

Make sure you're using my custom IL assembler together with rebasing (see related options) // #123 I can't say anything else without requested information.

[mikasoukhov]

I use Nuget package.

[mikasoukhov]

Think the reason was described here https://github.com/3F/DllExport/issues/175

Now no official instruction works with VS. Neither bat, no Nuget. Maybe someone will publish a quick solution or update the instruction. New projects for .NET Core is fully unsupportable )
