❔ Cannot open output file for writing
Hi all, trying to build my project with Visual Studio. Whenever I do I get an error from CSC stating the following:
To fix this, I have tried closing out of Visual Studio and deleting both the
Selkhound/output and Selkhound/Selkhound.API.Abstractions/obj directory, but the next time it builds I just get the same exception on build again. I also get this exception for the Selkhound.Client.dll file. Building using Visual Studio, with or without cleaning the solution, or using dotnet build on the command line has the same results.
The build log suggests that the projects are being built multiple times in parallel, though I'm not sure if that's a contributing factor here.
Any thoughts of what I might do to fix this?8 Replies
I also occasionally get errors about it not being able to resolve the
Microsoft.iOS or Microsoft.MacCatalyst libraries, but I think that these are just consequences of failing to build the Selkhound.Client project which is a Net7 Maui project.
So after cleaning and rebuilding a few times, the "cannot access file because it's being used by another process" error is exclusive to the Selkhound.Client project. I'm not getting it on the abstractions library anymore.
Apparently the answer was to do exactly the same thing I was doing, just about 6 more times.
Cleaning solution and then building the solution, and skipping any manual deletions, and I finally got it to work
No clue what happened differently@Saoirse (formerly Kanara) see this thread for a good explanation https://stackoverflow.com/a/3919906 I think you're seeing the same issue from here.

msbuild.exe staying open, locking files
I use TeamCity which in turn invokes msbuild (.NET 4). I have a strange issue in that after a build is complete (and it doesn't seem to matter if it was a successful build or not), msbuild.exe stay...
I don't know if there's a way to specify it in the csproj, the common solution is to just the env var MSBUILDDISABLENODEREUSE=1
I saw that, but in my case there is only one msbuild process and it closes when build is complete, so there's nothing remaining open to lock the files.
I could try the command line though
I'd just set the env var, reboot, and see if that helps
your symptoms match that issue to a T
any luck with testing that out?
I'll test this out today. Was focusing on getting my home lab set up
