"dotnet-ef migrations bundle" command broken on Linux with .NET 10

[ptffr]

Bug description

Starting from version 10.0.0-preview.1.25081.1 of dotnet-ef the bundle generation is broken on Linux.

Seems like it has a hard time finding the .deps.json file due to the backslash before Debug/

Build started...
Build succeeded.
The specified deps.json [/home/jello/dev/EfCoreBundleBug/EfCoreBundleBug.Api/bin\Debug/net10.0/EfCoreBundleBug.Api.deps.json] does not exist

To reproduce this in the provided repo just run dotnet ef migrations bundle -s EfCoreBundleBug.Api/ -p EfCoreBundleBug.Infra/

Also this issue seems to only happen when you have separate Startup and DbContext project.

Can also reproduce this on WSL2. it seems to be using \ instead of / for me (as well as everyone above) in part of the path, which works on Windows but not linux?

Reproduce this on macOS 26.

I can repro this as well with our CI/CD

- dotnet tool install --global dotnet-ef --version 10.0.0-preview.7.25380.108 # error

Gitlab Runner returns non 0 exiting Job.

- dotnet tool install --global dotnet-ef # works

[Andrzej-W]

I can confirm that this bug exists on macOS and dotnet 10 preview 7. I'm trying to add migration with:

dotnet ef migrations add

and I see a backslash instead of slash between bin and Debug folder

/<project path>/bin\Debug/net10.0/TestApp.deps.json

The same project on Windows works correctly.

Still broken on Mac with RC1.

Please can you get a fix out so I can try a RC version before the RTM?
