Materialdesigninxamltoolkit: Add Support For .NET Core 3.0

[Keboo]

WPF will support .NET Core 3.0.

This is a parent issue for any compatibility issues that are raised.

Any news or plans on this?

Same question. Any news about support for .NET Core 3.0 ?

Hi,

The only issue I currently have with porting this to netcoreapp3.0 is ShowMeTheXaml.
My last commit here https://github.com/jespersh/MaterialDesignInXamlToolkit removed all the ShowMeTheXaml (last elegantly, so all controls in a grid is a mess currently) for a quick revert once SMTX works.
So while it is entirely possible... The change most endangering is that this might not make .Net framework work (unless maybe 4.7.2)

@jespersh that is great. If you want to get a PR open we can start looking at getting it merged. I have a preview NuGet for ShowMeTheXaml that is out that adds .Net Core 3.0 support as well.

Awesome, Thanks! I just migrated my project to Core 3 and everything seems alright so far.

@dansef what commands are you building with?

[Keboo]

Closing as the work for this has been done. For those wishing to try this out there are a few things to know.

1. This is only available with the 3.0.0 _preview_ NuGet packages
2. MahApps is not currently supported with .NET Core 3.0, only the MaterialDesignThemes and MaterialDesignColors NuGet packages are expected to work. MahApps support will be forthcoming.
