@cinnamon-msft Can you check if you have multiple versions of Dev Home installed like the Dev version and the Canary version? If so can you make sure the sandbox extension for the dev version is turned off. That might fix the icon missing issue. I do believe I've seen the icon showing up before.

About the thumbnail: @pehammer would either you or Christian be able to get us a new image for sandbox scaled appropriately just like we did for Hyper-V and Dev Box? Looks like we're using the light version of bloom here for sandbox

I don't have a Dev version on this machine, just Preview and Canary, and Preview doesn't have Sandbox yet

Sounds good thanks Kayla just wanted to make sure it wasn't one of those multiple dev home version issues. Would you also be able to add the sandbox log file and the dev home log file to this issue as well when you can thanks!

Thanks, looks like the issue is that the build constants are not present in the sandbox project e.g for Hyper-V:

we have this line in the csproj file. It declares STABLE_BUILD and CANARY_BUILD as constants for the project. The Sandbox uses these same constants in this file just like we do for HyperV here. However since those constants aren't declared in the sandbox csproj file, the ifdef's go into the else case, where it looks for this file:

ms-resource://microsoft.windows.devhome.dev/Files/Assets/windows-sandbox-icon.png

and you'll notice that the package its using is microsoft.windows.devhome.dev , which like you said above doesn't exist on your machine. So therefore an image isn't found.

This should be a simple fix though, we just need to declare those constants in the sandbox csproj file in here somewhere: https://github.com/microsoft/devhome/blob/9db92955056f1be932ee500c876b6f62ff626c3b/extensions/WindowsSandboxExtension/WindowsSandboxExtension.csproj

Sandbox extension has been removed, so this issue is no longer applicable.
