CefSharp x86 dlls are copied to the root

[Chuprinenko]

Is there an existing issue for this?

• I have searched both open/closed issues, no issue already exists.

CefSharp Version

131.2.70

Operating System

Windows 10

Architecture

AnyCPU

.Net Version

net 4.8

Implementation

WPF

Reproduction Steps

2 projects in my solution solution (both .net framework 4.8, sdk-styled):

1. Empty library referencing CefSharp package

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <TargetFramework>net48</TargetFramework>
  </PropertyGroup>
  <ItemGroup>
    <PackageReference Include="CefSharp.Common" Version="131.2.70" />
  </ItemGroup>
</Project>

2. Console app referencing project 1

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>net48</TargetFramework>
  </PropertyGroup>
  <ItemGroup>
    <ProjectReference Include="..\CefSharpLib\CefSharpLib.csproj" />
  </ItemGroup>
</Project>

Also having these properties set in Directory.Build.props

<Project>
	<PropertyGroup>
		<CefSharpAnyCpuSupport>true</CefSharpAnyCpuSupport>
		<CefSharpPlatformTargetOverride>AnyCPU</CefSharpPlatformTargetOverride>
		<CefSharpBuildAction>None</CefSharpBuildAction>
		<AppendTargetFrameworkToOutputPath>false</AppendTargetFrameworkToOutputPath>
		<OutputPath>..\_output</OutputPath>
	</PropertyGroup>
</Project>

Steps to reproduce:

1. Build the solution

Expected behavior

Having common dlls in the root and specific dlss in the corresponding folders:

Actual behavior

Dlls from x86 are also copied to the root extremely increasing the size of the output:

Regression?

Broken in 121.3.70, before it worked

Known Workarounds

No response

Does this problem also occur in the CEF Sample Application

Not Tested

Other information

<CefSharpAnyCpuSupport>true</CefSharpAnyCpuSupport>
<CefSharpPlatformTargetOverride>AnyCPU</CefSharpPlatformTargetOverride>
<CefSharpBuildAction>None</CefSharpBuildAction>

These should only be set on your Exe project, not on your library project. CefSharpBuildAction should be NoAction for your library project (the default)

Troubleshooting

Add the following to your csproj/vbproj file at the end

<Target Name="CefSharpAfterBuildDebug" AfterTargets="AfterBuild">
    <CallTarget Targets="CefSharpAfterBuildDiagnostic" />
</Target>

Change your MSBuild project output verbosity to Normal:

1. Go to Tools->Options menu in VS
2. Open Projects and Solutions->Build and Run
3. Change the value of the MSBuild project build output verbosity. Pick Normal or higher

After you build, check the output window for a block of text that looks like:

>Target CefSharpAfterBuildDebug:
>  Target CefSharpAfterBuildDiagnostic:
>    CefSharp After Build Diagnostic
>    CefSharpBuildAction = Content
>    CefSharpPropertiesLoaded = true
>    CefSharpTargetDir =
>    CefSharpTargetDirAnyCpu32 = x86\
>    CefSharpTargetDirAnyCpu64 = x64\
>    RuntimeIdentifier = win7-x64
>    EffectivePlatform =
>    Platform = x64
>    PlatformName = x64
>    Platforms = x86;x64;AnyCPU
>    PlatformTarget = x64
>    CefSharpPlatformTarget = x64
>    PlatformTargetAsMSBuildArchitecture = x64
>    TargetFramework = net472
>    TargetFrameworkVersion = v4.7.2
>    libcef.dll exists = bin.net472\x64\Debug\net472\libcef.dll
>    CefSharpTransformXmlDllPath = C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\MSBuild\Microsoft\VisualStudio\v16.0\Web\Microsoft.Web.Publishing.Tasks.dll
>    NuGetProjectStyle = PackageReference
>    NuGetToolVersion = 5.11.1
>    OutputType = WinExe
>    OutDir = bin.net472\x64\Debug\net472\
>    Prefer32Bit = false

Confirm the PlatformTarget is as expected.
