Problem Description
------------------
If you are using the `using module` statement, it will load the module without any issues. However, if you make a change to the module and run the `using module` statement again without restarting your PowerShell session, it will not load the new modified module into memory, and instead will continue to use the old existing module that was loaded. This makes doing development with `using module` statements very tedious as you must continually reload your PowerShell session whenever you make changes to the module.

Ideally we would just use `Import-Module -Name [module name] -Force` to avoid this issue, but that does not work for importing `class`es, so the `using module` statement **must** be used.

Steps to reproduce
------------------
Create the following module and script files:

In `TestModule.psm1`:
```powershell
class TestClass
{
[string] $ClassPropertyText = "Initial text"
}

function Get-ModuleFunctionText()
{
return "Initial text"
}

Export-ModuleMember -Function Get-ModuleFunctionText
```

In `Test.ps1`:
```powershell
using module '.\TestModule.psm1'

$instance = [TestClass]::new()
$instance.ClassPropertyText

Get-ModuleFunctionText
```

Run `Test.ps1` and it will output:
```
Initial text
Initial text
```

Then modify `TestModule.psm1` to:
```powershell
class TestClass
{
[string] $ClassPropertyText = "Updated text"
}

function Get-ModuleFunctionText()
{
return "Updated text"
}

Export-ModuleMember -Function Get-ModuleFunctionText
```

Run `Test.ps1` again and it will still output:
```
Initial text
Initial text
```

Expected behavior
-----------------
When running `Test.ps1` the 2nd time, it should output:
```none
Updated text
Updated text
```

Environment data
----------------

<!-- provide the output of $PSVersionTable -->

```powershell
> $PSVersionTable
Name Value
---- -----
PSVersion 5.1.17134.228
PSEdition Desktop
PSCompatibleVersions {1.0, 2.0, 3.0, 4.0...}
BuildVersion 10.0.17134.228
CLRVersion 4.0.30319.42000
WSManStackVersion 3.0
PSRemotingProtocolVersion 2.3
SerializationVersion 1.1.0.1
```

Additional Info
----------------
The problem can be somewhat reduced by using _both_ the `using module` statement and `Import-Module -Force` statement, like this:
```powershell
using module '.\TestModule.psm1'
Import-Module -Name '.\TestModule.psm1' -Force

$instance = [TestClass]::new()
$instance.ClassPropertyText

Get-ModuleFunctionText
```

This code would result in the following output:
```
Initial text
Updated text
```

So here the module code was updated, but the `class` code was not.

Proposed Solution
----------------
To fix this issue I propose adding a `-Force` flag to the `using module` statement that forces the module to be reloaded into memory; the same way that the `-Force` flag works for the `Import-Module` cmdlet. This will allow developing code that uses the `class` construct to work much smoother.

I also proposed this same change to PowerShell Core at: https://github.com/PowerShell/PowerShell/issues/7654

# Steps to reproduce
1. I use a tool called rabtap to publish messages to rabbitMQ. Tool can be found here: https://github.com/jandelgado/rabtap
2. When I tap on an exchange and redirect output to a file.
-> It comes OK when I use this cmd on cmd prompt (i.e., as here): rabtap tap "myexchange:" --json > c:\tmp\usingCMDline.txt"
-> However if I redirect the output using powershell, I miss out the ending bracekt in the output file. rabtap tap "myexchange:" --json | Out-File "c:\tmp\ps02.txt" (see attached output)
# Expected behavior
Full JSON should output, as done by the cmd line redirect operator.

# Actual behavior
Miss out on the ending bracket.
More details on issues can be seen here: https://github.com/jandelgado/rabtap/issues/21

This looks like a bug on first sight but maybe there is a workaround that I am missing? Any idea why this is happening?

# Environment data

Currently module imports initiated via the RequiredModules statement in a Module Manifest do not allow for verbosity preference.

This results in a lot of additional noise for end users.
For example. If a DSC Resource module requires other modules, and imports them via RequiredModules in the Module Manifest then the following happens:

If an end-user is attempting to troubleshoot their DSC configuration they will utilize

Start-DscConfiguration -UseExisting -Verbose -Force

The results will be a verbose line for every cmdlet imported/exported from every included module. Which is A LOT of noise surrounding the verbose messages actually relevant to the end user.

There should be a way to avoid this. Something like this:

RequiredModules = @(@{ModuleName = "MSOnline"; ModuleVersion = "1.1.183.17"; Verbose:$false })

Currently there is no built in or easy way to have credentials stored to map persistent Drives via a script.

If you are mapping a drive for the same domain that the system is on then it will pass-through the current user's credentials, and it will save alternate credentials for the mapping in the current user session. However if you are trying to map a persistent drive for a share from a different non-federated domain, a workgroup computer, or for something on the same domain using different credentials, the password is not saved through logouts or reboots. Not only is the password not saved, but unless you manually put the credentials in Credential Manager (currently no native PS commands to do this, if you're scripting need to use the old Cmdkey commands) it will lockout the username specified in the credentials by trying to login with a blank password several times.

See here for a more detailed explanation of the mechanics and issue:
https://www.bloggingforlogging.com/2018/11/22/windows-mapped-drives-what-the-****-is-going-on/

I suggest that the New-PSDrive command be updated so that it adds the credentials to Credential Manager if both the -Persist and -Credential options are specified.

This would result in the expected behaviour of the drives being persistent through logouts and reboots, mirror the current behaviour when the drive is mapped via the GUI, and fix the account lockout issue that this can cause.

# Steps to reproduce

# Must use the format username@domain for username and be mapping share from different non-federated domain to reproduce
$Cred = Get-Credential
$Path = 'Path to the share'
New-PSDrive -Name 'P' -PSProvider FileSystem -Root $Path -Persist -Credential $Cred -Scope Global

# Expected behavior

The $Cred.username value gets stored in the registry under HKEY_CURRENT_USER\Network\P
in the UserName string value without alteration.

# Actual behavior

The domain of the system running the commands gets appended in the front of the username from the cred object when stored in the reg key.

For example if $Cred.Username is 'username@Domain1.com' and the computer running the command is on Domain2, the value stored in the reg key is 'Domain2\username@Domain1.com'.

This causes issues with persistence when mapping drives from another domain due to the system trying to authenticate against the wrong domain.

This behaviour only happens when mapping a drive using credentials from a different domain with the username in the format 'username@domain.com' being passed to New-PSDrive as a credential object. It does not happen when the credential object has the username in the format domain1\username, when specifying the username in the command and entering it into the popup, or when using a credential object for the same domain the system running the commands belongs to.

I have a filter in a script module that a does a little error formatting and flags the fact that it's seen an error. Most of the time, it seems to do its little job just fine. About once a week a sharing violation triggers some kind of infinite recursion and PowerShell emits the depth overflow error. The odd thing is that the function is not recursive. I've run procmon and I can see that the sharing violation happens just once - most of what happens after than is PowerShell writing to a pstrace log (I've wrapped the offending section in Trace-Command *). I can supply the .PML from procmon and the pstrace file, both for a failing instance and for a successful run 2 minutes later.

Problem:

When creating an object from the x509Certificate class the shell adds 3 script properties:

DnsNameList
EnhancedKeyUsageList
SendAsTrustedIssuer

The SendAsTrustedIssuer property causes Powershell to hit a CLR exception and hard crash when accessed.

Repro Code:

* Note: do this in a fresh session as it will crash the session

$Test = New-Object System.Security.Cryptography.x509Certificates.x509Certificate2
$Test | select *

Alternately,

$Test = New-Object System.Security.Cryptography.x509Certificates.x509Certificate2
$Test.SendAsTrustedIssuer

Crash dump:

Unhandled Exception: System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.
