…#7202)

The intent was to have the version of the PSSessionConfiguration name not include the `v` for the version string.  Also, Preview releases should standardize on `PowerShell.6-Preview` instead of clobbering `PowerShell.6` so that stable and preview can co-exist side-by-side.

Need to verify on Win10 IoT if `Install-PowerShellRemoting.ps1` is still needed anymore as it may be possible to run `pwsh -c enable-psremoting` from within Windows PowerShell Core removing the need for that script which duplicates `Enable-PSRemoting` capability.

Update: Not able to get the current master build working on Win10 IoT, getting `Invalid access to memory` error.  Will have to investigate this separately from this PR and keep `Install-PowerShellRemoting.ps1` for now.

Fix #7119

initial draft of changelog

Fixes #7074. This PR allows concurrent versions of the macOS launcher app to exist. The application name will be either PowerShell or PowerShell-preview. It is now dynamically built and removed post fpm to avoid post build conflicts, see #5262 .

Related #4708.

Format Microsoft.PowerShell.Commands.Utility.csproj by codeformatter with default options.

The codeformatter is used that I compiled with newest Roslyn packages (version 2.8.2).

Fix is to change the regex to allow for variable or no whitespace and associated tests to handle these two cases.

 Some values are not converted from json to PSCustomObject, because Newtonsoft.Json reads them and thinks they are metadata properties only useful for deserialization. This change makes Newtonsoft.Json "ignore" those properties so they are converted correctly from json to PSCustomObject.

- Make switch-statement report correct error position when it fails to evaluate the condition.
- Make for-statement report correct error position when it fails to evaluate the initializer.
- For the condition of `if/for/while/do-while/do-until` statements, the sequence point update is either duplicate in some cases (for `if/for/while`) which causes debugger to stop at the condition twice  before moving forward, or missing (for `do-while/do-until`) which causes debugger to skip the condition. They are fixed.

A comment from the existing `Utils.IsComObject` mentions that: "We can't use System.Runtime.InteropServices.Marshal.IsComObject(obj) since it doesn't work in partial trust."

Partial trust is a concept of Code Access Security (CAS)/Security-Transparent. CAS and Security-Transparent are no longer supported in .NET Core, so we should use `Marshal.IsComObject` instead.

Before the fix the TryConvertTo() is implemented in terms of Convert(), but with wrapping exception handling. This is costly performance wise. By inlining the implementation of ConvertTo(), and getting access to the FigureConversion output we can determine upfront on at least some occations that a conversion is not available.

Speed up the creation of PSObjects in CSV cmdlets by

- Use the overload Add(PSMember, bool prevalidated) for all objects except the first when adding the `NoteProperty` members.
- Add a new constructor to PSObject that preallocates the `_instanceMembers` collection with an initial capacity.
- Improve performance of AddToTypesXmlCache by avoiding an expensive copying of members just to check for the existence of one of them, perf is significantly increased, and allocations are reduced.
- Reduce allocations and GC pressure by preallocating and reusing `StringBuilders` and `List<string>` for line parsing in CSV cmdlets.
- Use `List<string>` instead of `Collection<string>` to get fewer virtual calls and better inlining.
- Reduce allocations by using a preallocated value factory in `TypeTable.GetMembers(ConsolidatedString types)`.
- Replace a `Linq.Any()` with a `List.Count > 0` in binder code.

The main gain is from taking advantage of the fact that all objects created by `Import-Csv` have the same shape (the same properties).

…<T> (#7435)

`PSMemberInfoInternalCollection<T>` uses OrderedDictionary class internally. `OrderedDictionary` in dotnet core 2.1 allocates `ArrayList` and `Hashtable` after any first using any property. Even if the `OrderedDictionary` object is actually empty.

The commit postpones the internal allocations until it's really necessary. Given that `PSMemberInfoInternalCollection<T>` is used in each PSObject and is often empty, this change dramatically reduces memory allocations.

Make sure that SettingFile arg is parsed before we load the settings

- Add ability to parse some setting before console host is created
- Trigger the Parse before the console host is created
- disable snapin loading from loading setting before this point
- re-enable mac logging tests.

Also, fix the following Travis-ci issues:

- make sure the Linux and macOS caches are separate to reduce the size
- update the macOS image to the closest image as used by the official build system (equivalent to VSTS hosted mac builds)

Default to DefaultConsoleWidth when DotNet says WindowWidth is 0

This resolves an issue in an environment like VSTS when pwsh is spawned and DotNet is not able to determine the Console Width.

This amounts so a speed-up in the order of 7x. Cmdlets that benefit from this are `Convertfrom-Json` and `Invoke-RestMethod`. There are three main changes:

- Convert from `JArray` directly to object array instead of creating a `List` and do `list.ToArray()`.
- Avoid iterating through `PSObject.Properties` to check for existing members, since that is a very slow and allocation heavy code path.
- Pre-allocate the members in `PSObject` by using the newly added constructor accepting an initial member count.
