描述
Summary of the new feature
Some times people don't properly close their Write-progress calls with a -Completed which can cause unexpected output, or "leftover" progress bars from commands that completed, but never closed their progress bars
Proposed technical implementation details (optional)
Write-Progress automatically stops showing open progress bars when execution is complete, but this means that if you are making an interface that does not properly close their Write-Progress progress bars with a Write-Progress -Activity $ActivityName -Completed then it stays open while other code is running, until execution stops.
It seems like in vanilla shell console, powershell can recognize that it is "done" (I'm guessing.... maybe something like the scope that created the Write-Progress is stopped? )
But if you do this in other environments, like ISE, then the Progress bars don't go away unless properly closed with a -Completed
Additionally there is the case that people who are running with something like -PercentComplete 100 but never closing.
A recommendation to close Write-Progress'es with a -Completed would effectively stop this problem
Possibly make sure each write-progress -Activity has a matching one with -Completed ? Not sure if there is a way to detect if it's closed in the same scope or if that might cause more problems
A potential problem for that would be things like People start it in the begin { } block write over time in the progress { } block, but not closing in the end { } block?
What is the latest version of PSScriptAnalyzer at the point of writing
As far as I can tell, it does nothing for this currently

调研方向
首先定位针对 PowerShell 命令的现有 analyzer 规则和测试;该 issue 提到了 Write-Progress 和匹配的 -Completed 调用,但没有指出任何文件或入口点。明确作用域边界以及 begin/process/end 块应如何工作,然后在实现之前定义覆盖普通命令类型和 async 命令类型的测试。
