I am getting this error whenever I enter a newline in the wpf code editor. This is a very high severity issue as it effectively makes the editor non functional.

<PackageReference Include="Alternet.Studio.Editor.Wpf" Version="8.1.4" />
<PackageReference Include="Alternet.Studio.Syntax.Parsers.Roslyn" Version="8.1.4" />

I am using version 4.3.1 of Microsoft.CodeAnalysis.*

System.ArgumentException

Hi Gregory,

At the time of releasing 8.1 Roslyn 4.3.1 was still in beta, so our Alternet.Studio.Syntax.Parsers.Roslyn package uses version 4.2.0. With this version autoindent works as expected.

We will look at supporting 4.3.1 shortly, until then it would be the best to use 4.2.0.

Kind regards,
Dmitry

Hi Gregory,

We have just pushed an update to NuGet (version 8.1.6), which is compatible with Roslyn 4.3.1.
We still use 4.2.0 by default, but it no longer crashes when you press Enter key if you update it to the newer Roslyn version.

Kind regards,
Dmitry
