We could combine three if in one or use ? operator in just single return.

src/Microsoft.PowerShell.ConsoleHost/host/msh/CommandLineParameterParser.cs

Maybe use TryParseSettingFileHelper?

We could exclude if-s and use single return.

sorry, I don't follow what you are saying.

Well, looking at the code, I made a guess.

I meant

return (match.Trim().ToLowerInvariant().IndexOf(switchKey, StringComparison.Ordinal) == 0) && (switchKey.Length >= smallestUnambiguousMatch.Length)

+                // We need to read the settings file before we create the console host
+                string[] tempArgs = new string[args.GetLength(0)];
+                args.CopyTo(tempArgs, 0);


Could you please clarify why we need clone args?

The existing code cloned the args. I don't want to break something by not cloning.

Reviewing the code. I don't think it has to be. I especially don't think it has to be twice. compromise, I'll remove the second clone, you file an issue to remove the first one.

Done #7457.

        internal bool AbortStartup


Should #region be in position with the line?

@iSazonov I believe I have addressed all your comments one way or another.

+        /// The index in args to the argument following '-SettingFile'.


The parameter name is generic but comment says that it is used only for '-SettingFile' - should the parameter name reflects the fact?

+                    consoleSessionSetting.ConsoleSessionConfigurationName : string.Empty;


Maybe use more short name like settings to get more short code strings.

this is an existing variable name. Please file an issues

iSazonov · 2018-08-06T03:22:38Z

src/Microsoft.PowerShell.ConsoleHost/host/msh/CommandLineParameterParser.cs

It is not clear that we get from the method. I'd replace var with explicit type.
Can we use:

(string switchKey, bool shouldBreak) = GetSwitchKey(args, ref i, null, ref noexitSeen);

Named argument for null will be good.

iSazonov · 2018-08-06T03:30:06Z

src/Microsoft.PowerShell.ConsoleHost/host/msh/CommandLineParameterParser.cs

Named arguments will be good for constants. Below I see some such patterns.

iSazonov · 2018-08-06T04:14:20Z

src/Microsoft.PowerShell.ConsoleHost/host/msh/CommandLineParameterParser.cs

+            path = path.Replace(StringLiterals.AlternatePathSeparator,
+                                StringLiterals.DefaultPathSeparator);
+
+            return Path.GetFullPath(path);


The method is used once and then we call File.Exist() where Path.GetFullPath() is called again.
https://source.dot.net/#System.IO.FileSystem/System/IO/File.cs,119
We could simplify the TryParseSettingFileHelper() method - remove try-catch there (line 429), move the line 574 to TryParseSettingFileHelper() before File.Exist()

existing code, please file an issue, the method was just changed from an instance to static

Done #7469.

+                configFile = NormalizeFilePath(args[argIndex]);
+            }
+            catch (Exception ex)


I believe we could remove the try-catch. See my comment for NormalizeFilePath() method.

None of my comments are blocking but recommend you reconsider adding release logic for the new Dbg.Assert calls.

I suggest updating the comment block at the top of the file to call out the change in format.
Other than that, this file LGTM

    - os: osx
-      osx_image: xcode8.1
+      osx_image: xcode9.4


I assume this means we won't be running tests against the prior OS version, right?

I found no differences in the log format, but yes correct

dantraMSFT · 2018-08-06T17:58:15Z

src/Microsoft.PowerShell.ConsoleHost/host/msh/CommandLineParameterParser.cs

The assert message is misleading. The method can only be called once since _dirtyEarlyParse is a static field.
Additionally, back this up with a release test or simply return if true. We don't run debug tests enough to catch this problem.

removed, I verified this can be run multiple times

dantraMSFT · 2018-08-06T17:59:52Z

src/Microsoft.PowerShell.ConsoleHost/host/msh/CommandLineParameterParser.cs

Back this up with a check in release mode. At a minimum, silently ignore and return.

dantraMSFT · 2018-08-06T18:03:33Z

The comment about writing errors doesn't appear to apply.

Updated comment (I have not pushed at this point.)

I've created issue #7460 to move this call to UnmanagedPSEntry.Start prior to PSEtwLog.LogConsoleStartup().

I've created issue #7462 to address the Start-Sleep workaround as well as the possible false-positive in filtering test below.

I'm pretty sure tuple field names are case sensitive.
