Error on Azure Pipeline for NuGet Pack task, using a SDK format .csproj, which autogenerates the .nuspec file:
The process cannot access the file 'D:\a\1\a\*.nupkg' because it is being used by another process.System.IO.IOException: The process cannot access the file 'D:\a\1\a\*.nupkg' because it is being used by another process. at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath) at System.IO.File.InternalDelete(String path, Boolean checkHost) at NuGet.Commands.PackCommandRunner.BuildPackage(PackageBuilder builder, String outputPath, Boolean symbolsPackage) at NuGet.Commands.PackCommandRunner.BuildFromProjectFile(String path) at NuGet.CommandLine.PackCommand.ExecuteCommand() at NuGet.CommandLine.Command.ExecuteCommandAsync() at NuGet.CommandLine.Command.Execute() at NuGet.CommandLine.Program.MainCore(String workingDirectory, String[] args))##[error]An error occurred while trying to pack the files.The .csproj file being built, uses TargetsForTfmSpecificBuildOutput:

But is based on this answer: https://stackoverflow.com/a/59893520/1231374
Note: Removing the custom package steps still causes the error.
There is an additional error before this, not sure if this could be related.
