MSB4220: Waiting for the currently executing task "Copy" to cancel

[bhalchandratk]

Is there an existing issue for this?

• I have searched the existing issues

Describe the bug

I can reproduce the issue - Build won't finish dotnet/extensions#1406 ( dotnet/sdk#9034 ) . This issue is still not fixed. Today I have installed fresh copy of VS 2022 version 17.5.1 Professional (64-bit) licensed edition in my organization computer. I was observing this issue for last 15 days recurrently and it was wasting my time like anything. Today i used process explorer to monitor what is going wrong and also started build using commandline dotnet build command with detailed logged enabled.

My observations are -

• Build keeps executing CopyToOutputDirectory action to copy apphost.exe from obj folder to bin folder for infinite amount of time. We cancel the build by Build -> Cancel option or control+c then onwards MSBuild stuck infite with error - MSB4220: Waiting for the currently executing task "Copy" to cancel. [ project name ].
• There are 3 MSBuild.exe running. First cancel stops/kills 1 MSBuild.exe
• 2 MSBuild.exe still running and then error starts coming on screen - MSB4220: Waiting for the currently executing task "Copy" to cancel

project type - asp.net core web api
.net version - 6.0 sdk
VS version - VS 2022 version 17.5.1

Expected Behavior

Build should not hang if it fails to copy the files, there should be some timeout and then throw exception notifying user of details. Right now i let it wait and build keeps waiting for hours ( i let it run overright and checked in the morning, it was still waiting for the copy operation to finish).

@JaynieBai Could you please try to repro this?

@bhalchandratk Could you attach a binlog so we can conduct further research ?

@JaynieBai , As this issue is happening in the work environment, this is not possible. It is regulated env. outside communication restricted. But I found few more details. This folder was under git repository and git process did not had any handle on this folder but git cache process was running.

Right now what I did is cloned new git repository, removed cloned code from git and then using it locally.

How is this folder created?

[bhalchandratk]

It was created with git clone only.

@bhalchandratk Could you figure it out why your Build keeps executing CopyToOutputDirectory action to copy apphost.exe from obj folder to bin folder for infinite amount of time?

@bhalchandratk I am unable to reproduce this issue without access to any logs. The issue had been reproduced on MacOS, as mentioned in dotnet/sdk#9034. May I know which operating system you are using?
