How to account for satellite dll's when using ClickOnce

[desjarlais]

My code is broken.
Am I the only one having problems with distribution by ClickOnce?

The EXE placed in the following path by ClickOnce,
C:\Users\USER\AppData\Local\Apps\2.0\2PAQMWD4.WKX\XZLEEH47.GTR\winf..tion_0000000000000000_0001.0000_5b14ef23fb2e66b5\WinFormsApp2.exe

Not reference DLL in the following path:
C:\Users\USER\AppData\Local\Apps\2.0\2PAQMWD4.WKX\XZLEEH47.GTR\winf..tion_0000000000000000_0001.0000_5b14ef23fb2e66b5\x64\Scintilla.dll and Lexilla.dll

Instead, it tries to reference the following DLLs, which results in an error:
C:\Users\USER\AppData\Local\Apps\2.0\2PAQMWD4.WKX\build\x64
( Why build\x64 ? )

.NET 6 Forms Application, publish through ClickOnce.

Description: The process was terminated due to an unhandled exception.
Exception Info: System.TypeInitializationException: The type initializer for 'ScintillaNET.Scintilla' threw an exception.
---> System.InvalidOperationException: Unable to locate the Scintilla.NET satellite assemblies : directory 'C:\Users\USER\AppData\Local\Apps\2.0\2PAQMWD4.WKX\build\x64' not found

It is not possible to have dlls added manually as content.

I thought these problems could be fixed by modifying the targets file in
C:\Users\USER\ .nuget\packages\scintilla5.net\5.3.3.18\build\ , but the code was incorrect.

LocateNativeDllDirectory does not account for apps delivered via ClickOnce, so this will have to be added somehow in the current logic of finding the satellite dll's.

I tried really hard to reproduce this on a .NET 6 WinForms project in VS 2022 but ClickOnce works without any issues because it seems to check whether <CopyToOutputDirectory> is used rather than whether it's a <Content>. The only configuration it doesn't work is with a .NET Framework project, which is fixed by the following change:

 <Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
   <ItemGroup>
     <NativeLibraries Include="$(MSBuildThisFileDirectory)**\*.dll" />
-    <None Include="@(NativeLibraries)">
+    <Content Include="@(NativeLibraries)">
       <Link>%(RecursiveDir)%(FileName)%(Extension)</Link>
       <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
-    </None>
+    </Content>
   </ItemGroup>
 </Project>
