Remove-Module PSScriptAnalyzer leaves behavior of removed module version

Removing a version of PSScriptAnalyzer does not remove its behavior from the session. I don't know much about this, but it looks like we're missing code to clean up after a remove.

Version 1.10.0 and 1.11.0 are somewhat different. For example, in 1.11.0, the Settings parameter tab-completes the .psd1 file names in the Settings subdirectory. Also, the PSPlaceOpenBrace and PSPlaceCloseBrace rules do not trigger on a one-line function, such as:

function Test-Brace1 () {"Hello, World"}

However, if you import one version (Import-Module), remove that version (Remove-Module), and then import the other version, the result is the same as if you imported only the first version.

This is important, because the results of the different module versions are perceptibly different.

REPRO:

0. Start a new session, e.g. new console. 
1. ipmo PSScriptAnalyzer -RequiredVersion 1.10.0 -Passthru
2. gmo | rmo
3. ipmo PSScriptAnalyzer -RequiredVersion 1.11.0 -Passthru 

Now, test one of the differing features.

4. Invoke-ScriptAnalyzer -Settings <TAB>    #Fails to tab complete, as in 1.10.0.
5. Invoke-ScriptAnalyzer -ScriptDefinition 'function Test-Brace1 () {"Hello, World"}' -Settings $home\Documents\WindowsPowerShell\Modules\PSScriptAnalyzer\1.11.0\Settings\CodeFormatting.psd1

This returns output that you shouldn't see any more in 1.11.0.

RuleName                            Severity     ScriptName Line  Message
--------                            --------     ---------- ----  -------
PSPlaceOpenBrace                    Warning                 1     There is no new line after open brace.
PSPlaceCloseBrace                   Warning                 1     Close brace is not on a new line.

The same is true if you reverse the order of the versions.

0. Start a new session, e.g. new console. 
1. ipmo PSScriptAnalyzer -RequiredVersion 1.11.0 -Passthru
2. gmo | rmo
3. ipmo PSScriptAnalyzer -RequiredVersion 1.10.0 -Passthru 

Now, we have 1.10.0 with 1.11.0 behavior:

4. Invoke-ScriptAnalyzer -Settings <TAB>    #Tab completes!
5. Invoke-ScriptAnalyzer -ScriptDefinition 'function Test-Brace1 () {"Hello, World"}' -Settings CodeFormatting

Version 1.10.0 should error on the one-liner, but it doesn't.

PS C:\> Invoke-ScriptAnalyzer -Settings CodeFormatting -ScriptDefinition 'function Test-Brace1 () {"Hello, World"}'
PS C:\>

Strange, I know. If you need more info, let me know. Thanks!

Commencez par la séquence Import-Module et Remove-Module de la reproduction, puis examinez le comportement de Invoke-ScriptAnalyzer après avoir basculé entre PSScriptAnalyzer 1.10.0 et 1.11.0. Comparez la complétion par tabulation des paramètres et les résultats de PSPlaceOpenBrace et PSPlaceCloseBrace ; le travail est terminé lorsqu’en supprimant une version, son comportement ne reste plus dans la session.
