Issue Description

Enabling verbose editorservice log level raises this warning:

2020-04-09 08:37:49.496 +02:00 [WRN] PSReadLine unable to be loaded: Unable to find type [Microsoft.PowerShell.PSConsoleReadLine,Microsoft.PowerShell.PSReadLine2, Version=2.0.0.0, Culture=neutral, PublicKeyToken=null].

I noticed as my keybindings stopped working (ctrl+r, etc) and coloring was not working anymore

Expected Behaviour

Should load

Actual Behaviour

Did not load

I have same issue on Windows. After upgrade PSReadLine doesn't work anymore.

[TylerLeonhardt]

Looks like the assembly version changed...
https://github.com/PowerShell/PSReadLine/blob/master/PSReadLine/PSReadLine.csproj#L7

I'll get a fix out and try to push a preview today. In the meantime, you can downgrade the version of PSReadLine to 2.0.0 to be unblocked.

[bgelens]

@TylerLeonhardt PSReadline 2.1.0-beta1 is shipped with the preview extension. Downgrade would be difficult :)

[TylerLeonhardt]

If you install the 2.0.0 version of PSReadLine, it'll come ahead of that path in the PSModulePath so it should work.

[bgelens]

I tried that already but it doesn't work like that apparently. This is from a fresh vs code session after uninstalling 2.1.0-beta1

2020-04-09 16:12:27.160 +02:00 [WRN] PSReadLine unable to be loaded: Unable to find type [Microsoft.PowerShell.PSConsoleReadLine,Microsoft.PowerShell.PSReadLine2, Version=2.0.0.0, Culture=neutral, PublicKeyToken=null].

[TylerLeonhardt]

Looks like you still have 2.0.1 in the first position. The assembly version in 2.0.1 was changed:

https://github.com/PowerShell/PSReadLine/blob/v2.0.1/PSReadLine/PSReadLine.csproj#L7

You need to grab 2.0.0 specifically to get it working, for now.

[bgelens]

As you can see in the screenshot, it is still loading 2.1.0-beta1 even though I don't have it in my own path anymore.

Still I did as you asked and removed 2.0.1. The extension is still loading 2.1.0-beta1 though. See integrated terminal output:

The read square shows the currently loaded psreadline. So the workaround does not work. (Which is another issue on it's own?)

This is from the editorservices log:

2020-04-09 19:32:37.615 +02:00 [WRN] PSReadLine unable to be loaded: Unable to find type [Microsoft.PowerShell.PSConsoleReadLine,Microsoft.PowerShell.PSReadLine2, Version=2.0.0.0, Culture=neutral, PublicKeyToken=null].

[TylerLeonhardt]

Ah I guess we sort by version... Well, you can delete that folder and things will work again. I have a PR out to fix this.

[bgelens]

Thanks @TylerLeonhardt! Looking forward to the next preview release :)

[bgelens]

@TylerLeonhardt The workaround not working is indeed caused by sorting: https://github.com/PowerShell/PowerShellEditorServices/blob/master/src/PowerShellEditorServices/Services/PowerShellContext/Session/PSReadLinePromptContext.cs#L36
