Reproduction Steps

Summary ijwhost.dll bundled in CefSharp.Common.NETCore was downgraded to an older version starting from 144.0.120, compared to 140.1.140.

Steps to Reproduce Install CefSharp.Common.NETCore 140.1.140 and 144.0.120

Compare ijwhost.dll file versions under runtimes\win-x86\lib\net6.0\ in the NuGet cache

Observe the version downgrade

Expected behavior

ijwhost.dll should be updated to the latest available version with each CefSharp release, or at minimum should not regress to an older version.

Actual behavior

Version details CefSharp Version - ijwhost.dll Version

  • 140.1.140 - 6.0.3624.51421
  • 144.0.120 - 6.0.3324.36610
  • 145.0.260 - 6.0.3324.36610

Impact Applications using CefSharp.Common.NETCore >= 144.0.120 will have an older ijwhost.dll copied to their build output, overriding any newer version provided by the .NET runtime packs on the build machine.
