Cefsharp (Libcef.dll) program crashes after opening web page from WPF

[US-CPHAM]

Hello everyone. I am having an issue with using CefSharp to open a web page from a WPF application.

In WPF, I open a window, and in that window, I use ChromiumWebBrowser (CefSharp) to navigate to a web page. When I run it in the Debug environment, there are no issues, and everything runs smoothly. However, when I build the application and run it in the production environment, the program crashes a few seconds after the website screen is displayed. Checking the Windows Event log, I get the following result:

Faulting application name: Test.exe, version: 6.0.0.135, time stamp: 0x6707d47d
Faulting module name: libcef.dll, version: 129.0.11.0, time stamp: 0x66fb0c5a

What's the production environment exactly?

There really isn't a lot to go on here.

Additional you can use https://github.com/cefsharp/CefSharp.MinimalExample as a reference for testing purposes.

I had a same problem, but I solved with the example project @amaitland mentioned.
app.manifest file is the key. More specifically you should add compatibility block like below.
Without this block, the example project also get crashed.

<?xml version="1.0" encoding="utf-8"?>
<asmv1:assembly
  manifestVersion="1.0"
  xmlns="urn:schemas-microsoft-com:asm.v1"
  xmlns:asmv1="urn:schemas-microsoft-com:asm.v1"
  xmlns:asmv2="urn:schemas-microsoft-com:asm.v2"
  xmlns:asmv3="urn:schemas-microsoft-com:asm.v3"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

	<compatibility xmlns="urn:schemas-microsoft-com:compatibility.v1">
		<application>
			<!-- A list of all Windows versions that this application is designed to work with. 
      Windows will automatically select the most compatible environment.-->

		</application>
	</compatibility>
</asmv1:assembly>

One more thing, you should add this line to csproj file inside <PropertyGroup>.

<ApplicationManifest>app.manifest</ApplicationManifest>
