Unable to initialize module when not using IncludeAllContentForSelfExtract, .net 5

[DanielRBaird]

I'm currently working on upgrading an application to .net 5, and I'm trying to take advantage of the changes to single file publishing so that we don't need to extract so many files.

Unfortunately when using the latest netcore version of cefsharp this results in a crash unless you use IncludeAllContentForSelfExtract.

This can be reproduced in the minimal example, but removing the IncludeAllContentForSelfExtract setting and publishing a single file for net-5.0.

The result is this crash:

Application: CefSharp.MinimalExample.WinForms.netcore.exe
CoreCLR Version: 5.0.521.16609
.NET Version: 5.0.5
Description: The process was terminated due to an unhandled exception.
Exception Info: System.TypeInitializationException: The type initializer for '<Module>' threw an exception.
 ---> System.ArgumentNullException: Value cannot be null. (Parameter 'path1')
   at System.IO.Path.Combine(String path1, String path2)
   at CefSharp.Initializer.ModuleInitializer()
   at .cctor()
   --- End of inner exception stack trace ---
   at CefSharp.MinimalExample.WinForms.ProgramPublishSingleFile.Main(String[] args)

Location of the crash: Initializer.cs

Ultimately this is caused because net 5 returns an empty string for Assembly.Location now, so another method is needed to get the proper paths.

Should this be made into a bug issue?
Has anyone figured another way around it without including all content for self extract?

A PR referencing this discussion would be preferable.

If your embedding the native resources then I'd be surprised if this is possible though your welcome to do your own research, reach out to someone on the dot net team perhaps? #3407 has my research to date

If you don't embed the native resources then this should be possible (from memory this is the default).

When Assembly.Location is empty we'll fallback to AppContext.BaseDirectory

Changes will be in the 90 release, commit 82daa95

Cool, thanks for the info @amaitland.
