Did you install the Visual C++ Runtime?

As it stands this will be converted to a discussion as it's unlikely a bug.

[amaitland]

Testing with the MinimalExample using

dotnet publish CefSharp.MinimalExample.WinForms.netcore.csproj -f net6.0-windows -r win-x64 -p:PublishSingleFile=true -p:IncludeNativeLibrariesForSelfExtract=true -p:IncludeAllContentForSelfExtract=true --self-contained true --verbosity n

Testing with the Windows 10 Sandbox and the resulting single file exe works as expected after installing the VC++ 2019 x64 Runtime.

Converting to discussion as unable to reproduce issue.

[amaitland]

Using the same exe and running on a Windows 11 Pro VM the example runs as expected after installing the VC++ x64 Runtime.

[EVA-SS]

installation package contains MICROSOFT VISUAL C++ 2019 RUNTIME x64

I'm trying

[amaitland]

PublishSingleFile doesn't create an installation package.

I'd suggest you test with the minimal example and manually install the runtime for testing purposes.

BUG

environment

[amaitland]

Did you publish with the command line argument I provided above?

Don't assume because it's not working that it's a bug.

[EVA-SS]

If there's no other way, I'm thinking of changing to Microsoft.Web.WebView2

[EVA-SS]

yeah

dotnet publish CefSharp.MinimalExample.WinForms.netcore.csproj -f net6.0-windows -r win-x64 -p:PublishSingleFile=true -p:IncludeNativeLibrariesForSelfExtract=true -p:IncludeAllContentForSelfExtract=true --self-contained true --verbosity n

I haven't encountered this problem. My colleagues are also Win11. They are all normal

[amaitland]

This is the customer's computer, not developed

I am a remote customer computer. Our computer is normal,

This is important information and should have been included earlier.

Test using the Windows sandbox, confirm that it works there in isolation. Make sure to install the VC++ runtime.

The customer computer is likely missing dependency. I don't have Windows 11 Home setup for testing. Try creating your own virtual machine. Good practice to have virtual machines for every environment you plan to support.

@EVA-SS do you have a fix? My customer suffer the same problem, my app is wpf, but his pc throw the samiliar error.
the C++ 2015-2019 is already installed on his pc

我这客户电脑上也是直接crush 翻windows日志是runtime报错 打包也selfcontain了 他也有c++restribution

[EVA-SS]

快2年了，看起来新版本依旧有这样的问题，最离谱的是，并不是所有电脑都有这个问题，我已经替换Microsoft.Web.WebView2来实现了，虽然没有CEF好，但是看起来没出问题

[amaitland]

• What operating system?
• Is it just the one computer that is having problems?
• Have you tested using the Windows Sandbox?
• What are you targeting x86/x64/arm64?
• What RuntimeIdentifier have you specified?

the C++ 2015-2019 is already installed on his pc

The VC++ runtime is architecture specific, there are x64, x86 and arm64 versions. Make sure you have the one installed that matches your application.

English only please.

@amaitland I think you've found the truth, I just installed an x84 version and fixed. Thank you
