Developing .NET Core (v8) app that's deployed to local Service Fabric cluster (1 node).
App is deployed, but when I do some change in VS and try to start debugger again with F5, build fails because app DLL is locked by running app in the Service Fabric, so i have to manually go to SF and remove the app before i can redeploy/start debugging.
That worked fine before, but with latest few versions of SF and VS, it can't remove the SF app on its own before redeploying it.

Hello, @Hrvoje Hudo ! This may be a Visual Studio issue but I'm reaching out to the Service Fabric team to see if there are any known issues with recent updates. Thank you for reporting this!
Hello, @Hrvoje Hudo ! Quick update: we are investigating if there have been any Service Fabric changes that might have caused this.
Thanks. Btw, this is happening on 2 machines, one recently reinstalled Windows and all the dev tools, and everything is up to date. Same issue, have to manually delete the app before i can publish it again, or even run the tests.
Hello, @Hrvoje Hudo ! Quick update: So far it does not appear that there has been a change within Service Fabric, although there has been a related issue in the past with Visual Studio:https://developercommunity.visualstudio.com/t/visual-studio-complains-of-file-being-locked-by-se/60718
Hello, @Hrvoje Hudo ! We haven't been able to find a change within Service Fabric that has caused this issue. Since there has been a related issue with Visual Studio in the past, you can either create a new post under Visual Studio (which may get more attention) or we can change the tag of this post if you would prefer.
