GPU process exited unexpectedly

[deanmaoataristocrat]

What exactl is this issue about? I did everything I could, and still got this exception. Can anyone please help? Tried all different settings as well. The simple example worked fine.

we are embeding cef in a WPF app.

@amaitland sorry to ping you, do you have any idea about above errors? thanks

[amaitland]

Please use Code Blocks to format your code in future. I had to edit your posts to get the code to actually show.

The simple example worked fine.

If the CefSharp.MinimalExample.netcore.sln solution build and run successfully targeting .Net 6.0 then the question is what's different about your solution?

hmmm, still showing the same errors, any clues?

The CefSharp.BrowserSubprocess.exe failed to launch. Where there any errors in the event viewer?

and some other propertities:

  <PropertyGroup>
    <TargetFramework>net6.0-windows</TargetFramework>
    <UseWPF>true</UseWPF>
    <UseWindowsForms>true</UseWindowsForms>
    <CefSharpAnyCpuSupport>true</CefSharpAnyCpuSupport>
    <RuntimeIdentifier>win-x64</RuntimeIdentifier>
    <ApplicationManifest>app.manifest</ApplicationManifest>
  </PropertyGroup>

<CefSharpAnyCpuSupport/> is only relevant when targeting .Net 4.x, it has no relevant when targeting .Net 6.0 and can be removed.

csproj files have following nuget packages:

    <PackageReference Include="cef.redist.x64" Version="110.0.25" />
    <PackageReference Include="CefSharp.Common.NETCore" Version="110.0.250" />
    <PackageReference Include="CefSharp.OffScreen.NETCore" Version="110.0.250" />
    <PackageReference Include="CefSharp.Wpf.NETCore" Version="110.0.250" />
    <PackageReference Include="chromiumembeddedframework.runtime.win-arm64" Version="110.0.25" />
    <PackageReference Include="chromiumembeddedframework.runtime.win-x64" Version="110.0.25" />
    <PackageReference Include="chromiumembeddedframework.runtime.win-x86" Version="110.0.25" />

The cef.redist.x64 is only used by the older .Net 4.x nuget packages and should be removed. For PackageReference you should only include the top level packages. For just WPF you only need to include:

    <PackageReference Include="CefSharp.Wpf.NETCore" Version="110.0.250" />

I had to force it with older version by adding a dependency json file. Just in case anyone else facing the same issue:

Force what to use an older version exactly? We don't ship a .deps.json file typically as there's some problems with SelfContained/SingleFile builds. Does your project use System.Test.Json?

I don't recommend creating your own .deps.json, your replying on implementation details here which could easily change between versions.

The approach I recommend is Self Hosting the BrowerSubProcess, basically use your own application exe instead. There's instructions at https://github.com/cefsharp/CefSharp/wiki/SelfHost-BrowserSubProcess (this is a new wiki page, feedback is encouraged/welcomed).

[deanmaoataristocrat]

I will revert more details later, got some urgent work, no much time to investigate further.

[deanmaoataristocrat]

ok, I finally fixed it reliably. I used net6 version. however somehow, it just won't work, I had to force it with older version by adding a dependency json file. Just in case anyone else facing the same issue:
