What is the alternative of Microsoft Blend on Linux for editing the UI XAML files in Noesis GUI.
How can I visualize them?

Also, on Linux launching the Xaml Player v3.1.0 indicates drag and drop XAML files here, however, dropping files have no response.
After some time it mentions "Invalid License https://www.noesisengine.com/trail".

I am evaluating Noesis GUI on Linux.

We are working on an alternative for having Blend on Linux but for now the only way is using XamlPlayer + text editor like VSCode.

Also, on Linux launching the Xaml Player v3.1.0 indicates drag and drop XAML files here, however, dropping files have no response.

Drag and Drop is not implemented on our app-framework for Linux, please open a ticket about it. For now, you can pass the XAML at the command line.
