ProjFS on containers?

[dsopscak]

We're looking into running Visual Studio based builds in a windows container. Several workloads depend on a testing component which depends on the windows feature "client-projfs". Our visual studio install fails on the servercore:ltsc2019 base image trying to enable that feature. I've seen indications that ProjFS is not supported on windows containers. Is this still the case? If so, is support for ProjFS anticipated any time soon?

@dsopscak Just to confirm, was it that installing Visual Studio failed because of a ProjFS package? You should be able to install Visual Studio Build Tools inside a Windows Server Core 2022 container. And I'd recommend doing this with 2022 as long-term support for 2019 has ended.

We're trying to install several workloads using vs_enterprise.exe. Three of those, including the .net asp web and desktop workloads, appear to depend on ProjFS and the installation fails when trying to enable that feature. We're trying to quickly replicate the setup we're using on VM-based build agents. Looking ahead, we'll be creating more, finely tuned containers with the tools intended for headless use, but hoped to get something up quickly to use with an existing build process.

@vrapolinario @thecloudtaylor @fady-azmy-msft Would you know about whether this use case is supported?

I can't speak for ProjFS itself, but I'd guess it's looking for something in the OS that is not present. @dsopscak can you please provide the full error you are seeing? Also, have you tried this process with the server image versus the server core one?

Sorry, had been away from this problem for a while. Digging back into it now and will have more information in the next day or so. For now I can say that I'm still getting an error in the same area as before, using the base image

mcr.microsoft.com/windows/servercore:ltsc2019

Per @vrapolinario 's advice I looked for a server image to use in place of servercore but didn't find one. I tried

mcr.microsoft.com/windows:ltsc2019

thinking that might be the thing he meant. While that was definitely a bigger image, it didn't work at all since windows add feature didn't work on that which I need for some other, more basic, setup. If there is something else I should be trying, I'd love some advice about specific base image URL's I might try. I feel like I'm working a bit in the dark with trial and error putting together base image URLs as I haven't found information pertaining to exactly what is available.
