Any plans for supporting .NET Core 3.0?
It should be released the first quarter 2019 with support for WinForms.
We are evaluating the migration of our solution (an enterprise C# codebase with around 1 million lines of code) and the Portability Analyzer from Microsoft detects just a few issues with the ActiproSoftware.SyntaxEditor.Addons.DotNet.WinForms.dll assembly. The other two assemblies we are using (the control itself and the XML addon) are 100% portable.
The issues are with System.AppDomainSetup and System.AppDomain as they are not supported on Core.
