Also having this issue https://github.com/Baseflow/XF-Material-Library/issues/206

I'm missing default resources and I don't know why.

The line with the issue is this one https://github.com/Baseflow/XF-Material-Library/blob/e1779f84e95cffe1a6a00bdd129cc2c8b25c63c5/XF.Material/UI/Dialogs/MaterialConfirmationDialog.xaml#L19

I'm using this configuration in a modular app with prism.

XF.Material.Forms.Material.Init(this);
InitializeComponent();
XF.Material.Forms.Material.Use("Material.Configuration");

I have the configuration in a separate project.

I was having a problem with Material.Dialog.Width. It seems default resources arent being merged. I add it manually and after that, I have the same error.

**System.InvalidOperationException:** 'Invalid on Color.Default'

Can you help me with that? cc @martijn00

@kerberosargos can you help me with this?

I am sorry I have seen your post late. Can you try this package? XF.Material.1.7.7.1.zip

[luismts]

It didn't work for me @kerberosargos . Also I don't know if I did correctly. That package is for the .netstandard project?

My workaround was:

XF.Material.Forms.Material.Init(this);
InitializeComponent();
XF.Material.Forms.Material.Init(this); // WORKAROUND: Solving some reference issues

Without that line, controls break the app. The controls are showing but we cant interact with them because are breaking the app.

As I said I have a separated project with all the resources the app use including styles, colors, etc.

You should remove installed plugin after that you should install this one. Set your nuget settings as local for installing.

You told that you have a configuration in separate project, but have you added that ResourceDictonary in you main App's ResourceDictonary to MergedDictonaries section ?
