dotnet-dump collect silently fails if the user running the process does not have permission to write

[xPaw]

$ dotnet-dump collect -p 736578

Writing full to /home/xpaw/core_20250211_130126
Complete

But in reality the file was not actually written, because the process I was dumping was running as another user (I ran the dump command as root) which didn't have permissions to write to my home folder. When I changed working directory to /tmp it actually worked.

The tool should report an error if it fails to actually write the file instead of saying complete.

I am using .NET 9.0.102 on Debian 12.

There's two issues:

• the IPC should have an error code.
• The errors are directed stream - it should have displayed on your side.
