Adds warning messages to the Enable-PSRemoting and Disable-PSRemoting cmdlets that informs the user that the cmdlets only affect PSCore6 remoting endpoint configurations and not Windows PowerShell configurations.
PR Context
As documented, Enable-PSRemoting and Disable-PSRemoting affects all PowerShell remoting on a Windows system, and Windows users will likely expect the cmdlets to continue working this way in PSCore6. However, these cmdlets currently affect only PSCore6 remoting endpoints when run in PSCore6 and have no effect on Windows remoting endpoints.
Remoting relies on Windows native crypto APIs to pass a secure string. Of course these APIs don't work on non-Windows. However, the remoting code does not expect this to fail so ends up in a hang waiting for an event that never happens.
Have not figured out how to return an error to the user in the case `Get-Credential` is called within a PSSession. Currently it just quietly closes the remote connection. @PaulHigin can you give a pointer to where this code would exist? Debugging the current code, it has a bunch of error handlers which just result in the pssession being closed and not sure where throwing is appropriate.
Fix https://github.com/PowerShell/PowerShell/issues/8723
## PR Context
Fix is to provide implementations of the Win32 native pinvoke apis that throw an exception. The reason to do it this way is that there's a bunch of code that calls some of the APIs of the wrapper .Net class to setup structures that eventually get passed to the win32 api. Throwing in the managed class causes other things to fail early that should work on non-Windows.
Fix#8028
This change adds support for specifying the underlying type for an enum:
```powershell
enum MyEnum : long
{
A = 0x0FFFFFFFFFFFFFFF
B
}
# or
enum MyByte : byte
{
A = 0x01
B = 0x02
C = 0x03
D
}
```
* support fuzzy matching with get-command and on CommandNotFound exception, show suggestion
* fix CodeFactor issues
* change algorithm to use Damerau-Levenshtein Distance which is more useful in finding close matches
change ellipsis when truncating to single unicode character
reset console output if previous column contains ESC
update existing format-table tests
If content included a VT100 ESC sequence (like changing color), this affected all output after that cell in the table. Fix is to detect that a cell contained ESC and reset the console after it. Also, change the 3 character ellipsis `...` to use the single unicode character `…` so that more text is available.

'cd +' adds the ability to revert 'cd -' by having another bounded stack with the same limit for 'redo' actions.
Behaviour is similar to back/forward navigation in explorer.exe
When the location is set to a path and the redo stack is non-empty then the redo stack gets flushed.
When cd + happens, then the redo stack is pushed to as well for a more intuitive way of navigating backwards and forwards.
All the work is done of course on the Set-location cmdlet, which is aliased to cd on all platforms.
ByRef-like types are supposed to be used on stack only, so we need to fail gracefully when accessing properties, calling methods, or creating objects related to ByRef-like types.
Before the fix when using Get-Variable or Get-Alias cmdlets with the -Scope parameter with wrong value, the error message refers to 'scopeID' parameter instead of 'Scope'.
- Add `%WINDIR%\System32\WindowsPowerShell\v1.0\Modules` (Windows PowerShell $PSHOME) to the end of the default PSCore 6 module path (i.e. the module path as initially set at startup).
- Cause an error to be thrown by `Import-Module` when a module with `CompatiblePSEditions` not containing `"Core"` is being loaded from the 'System32' module path.
- Suppress output of modules listed by `Get-Module -ListAvailable` from Windows PowerShell $PSHOME when `CompatiblePSEditions` does not contain `"Core"`.
- Introduce the `-SkipCompatibilityCheck` switch parameter on both `Import-Module` and `Get-Module` to respectively allow importing incompatible modules and listing incompatible modules.
- Adds a `PSEdition` column to the `PSModuleInfo` table view format.
- Ensures that completions are not given for incompatible modules on the System32 module path.
Add support to experimental features
RFC: https://github.com/PowerShell/PowerShell-RFC/pull/114
Goals:
Allow experimental features to be declared by PowerShell engine and modules.
Allow experimental features to be enabled via powershell.config.json
Allow Function, Cmdlet, parameters and parameter sets to be shown to the user or hiden from the user depending on whether the associated experimetnal feature is on or off.
Allow discover experimental features using cmdlet Get-ExperimentalFeature
Update PowerShell Direct to try pwsh then fallback to powershell
- Forward port changes from Windows Powershell to fall back
- change the order from powershell->pwsh to pwsh->powershell
fixes#7237
* Implement location history feature for Set-Location.
This makes it possible to go back to the last directory using 'cd -',
which is exactly the same syntax as on Linux shells.
* Use an existing stack implementation instead of relying on an environment variable and move logic for 'cd -' into the internal class of SessionState.Path.SetLocation
Keep the (additional) setting of an environment for Unix system in case of mixed usage of cd and Set-Location to provide consistency.
* Use a bounded stack with a limit of 1000 and adapt tests.
Remove setting environment variable on Linux as discussed in PR.
* Fix test: use get-location explicitly to avoid subtle difference in the path string (e.g. an additional slash at the end)
Make syntax to .net call of environment consistent with surrounding code
* Move initialization of _workingLocationHistoryStack into constructor of SessionStateInternal and set the limit to 20 as discussed in PR 5051.
* Make new BoundedStack class in engine utils internal
Measure-Object should handle `ScriptBlock` properties. Fixed by renaming `MshExpression` to `PSPropertyExpression` and making it public. Then in `MeasureObjectCommand`, lifting it up to the parameter level. Previously the implementation exposed the Property as a string and
wrapped it internally as a `PSPropertyExpression`. Now the parameter type is `PSPropertyExpression` directly allowing for both wildcard strings and `ScriptBlock`.
`PSPropertyExpression` now lives in a public namespace where it can be used by cmdlet and script authors to easily add the same type of functionality to their commands. I also modified `PSPropertyExpression` to handle hashtables properly as objects so
@{prop = 3} | measure-object prop
and
@{prop = 3} | measure-object {$_.prop}
will work the same. (Previously the example using just the property name would fail.)
Refactor code to make it easier to maintain and a little faster. Changes are as follows:
1. Support finding a matching signature with variance. But make PowerShell prefer exact match over a match with variance.
2. The metadata signatures in `PSMethod<..>` are generated based on the array of method overloads in `MethodCacheEntry.MethodInformationStructures`, in the exact same order. So in `LanguagePrimitive.ConvertViaParseMethod`, when we try to figure out if there is a match using the metadata signatures in `PSMethod<..>`, we can get the index of the matching signature, and the same index should locate the matching method in `MethodCacheEntry.MethodInformationStructures`. Therefore, we don't need to compare signatures again in the actual conversion method, and instead, we can just leverage the index we found when figuring out the conversion in `ConvertViaParseMethod`.
- This gets rid of the reflection call `GetMethod("Invoke")` and the subsequent signature comparisons in the final conversion method.
- Also, when comparing signatures using `PSMethod<..>` in `ConvertViaParseMethod`, we can just use the generic argument types of each `Func<..>` metadata type, instead of calling `GetMethod("Invoke")` and then `GetParameters()`. This makes the code for comparing signatures simpler (the type `SignatureComparator`).
- Move `MatchesPSMethodProjectedType` from `PSMemberInfo.cs` to the type `SignatureComparator` in `LanguagePrimitives.cs`, as it's closely related to the signature comparison. Also, renamed it to `ProjectedTypeMatchesTargetType`.
- These changes make PSMethod-to-Delegate conversion a little faster, but no big improvement, as the true bottleneck probably is in delegate creation(?). Actually, the performance of this conversion is not critical at all at this moment because this feature should rarely be used in any hot script path. So this exercise is mainly for fun.
3. Remove `PSEnum<T>`. We can directly use enum types when constructing the metadata type `Func<..>`.
4. Remove the code that generates metadata signatures for generic method definitions (call `MakeGenericMethod` with fake types like `GenericType0`, `GenericType1`). This is because:
- We don't support convert generic method to delegate today, so may be better not spending time on preparing the metadata signature types for those methods.
- When the day comes that we need to support it, it's better to use generic argument types directly to construct the `Func<..>` metadata types. I left comments in `GetMethodGroupType` method in `PSMemberInfo.cs` to explain why that approach is better.
[breaking change] Clean up code related to the uses of `CommandTypes.Workflow` and `WorkflowInfo` in `System.Management.Automation`. This change mainly affects help provider code.
This PR includes a few minor breaking changes:
- Change the `public` constructors of `WorkflowInfo` to `internal`. We don't support workflow in PSCore, so I think it makes sense to not allow people to create `Workflow` instances.
- Remove the type `System.Management.Automation.DebugSource` since it's only used for workflow debugging.
- Remove the overload of `SetParent` from the abstract class `Debugger` that is only used for workflow debugging.
- Remove the same overload of `SetParent` from the derived class `RemotingJobDebugger`.
