Could not copy the file "XXXX\apphost.exe" because it was not found

Issue Description

Running dotnet publish after deleting obj and bin directories fails until I taskkill the dotnet process.

Steps to Reproduce

• Download the latest SDK installer build (I’m using 7.0.100-rtm.22470.23)
• Unzip it to e.g. C:\dotnet7 and then run the following exact steps:

cd c:\dotnet7
set path=%cd%;%path%
dotnet new console -o test
cd test
dotnet publish -r win-x64 -c Release
rmdir /S /Q obj
rmdir /S /Q bin
dotnet publish -r win-x64 -c Release

Expected Behavior

The second publish succeeds, same as the first.

Actual Behavior

C:\dotnet7\sdk\7.0.100-rtm.22470.23\Microsoft.Common.CurrentVersion.targets(5145,5): error MSB3030: Could not copy the
file "C:\dotnet7\test\obj\Release\net7.0\win-x64\apphost.exe" because it was not found. [C:\dotnet7\test\test.csproj]

Analysis

Something with the dotnet.exe process that hangs around after the first publish. If I taskkill /im dotnet.exe /f before the second publish, it works. It took a while to figure that out.

Here’s the binlog from the failed attempt: msbuild.zip
