File not found: 'Caliburn.Micro.AssemblySource.Instance'

[mennowo]

Hello,
when trying to run the most basic application with gemini, I get the following (inner) exception when running the app:

Could not load type 'Caliburn.Micro.AssemblySource' from assembly 'Caliburn.Micro.Platform, Version=3.0.3.0, Culture=neutral, PublicKeyToken=8e5891231f2ed21f'.

Building works fine. Also, version 3.0.3.0 of Caliburn.Micro is installed, I downgraded that from 3.2.0. Note that I had to install Caliburn.Micro manually, the package manager gave an error on trying to install GeminiWpf as a dependency without install Caliburn.Micro first.

I am unsure how to resolve the exception. Any help appreciated!

Greets, Menno

It is a problem with the Caliburn.Micro it self. There is barely any tutorials, and they are mostly from 2016/2017. I was using .NET Framework 4.7.2 and i had the same error. So i went to .NET Framework 4.5.2 and when i tried to install gemini, i got a install failure, it was that Caliburn could not install a package "System.Windows.Interactivity", so i installed it, and gemini could install Caliburn easily. Hope this will be useful for anyone.

System.Windows.Interactivity is legacy and not used except by old packages. As I recall, older versions of MahApps required that file. I don't remember Caliburn requiring that file, but it is possible. Most packages use Microsoft.Xaml.Behaviors.Wpf now.
