Mmmh I don't understand. xmlns is just xml namespace, it's like a using in c#. |

I am having issues where I have never figured out how to use Sharnado CollectionView. I have looked at the sample page for Maui. It looks like a standard hello world sample to me. I have tried adding I can almost guarantee it is my understanding of dotnet and my lack of knowledge on this that is the issue. I have heard your package is easy to use and implement. I imagine to anyone with experience what I am asking is confusing. I have looked at the various items in this repo and I am completely lost. I will be looking at it more when I get more experience. I keep coming back every few months and I am still completely lost. I was fine figuring out how to use sql-lite, media element. All of the basic stuff for xaml. But I have to admit looking at the code in this project I have a long way to go. I thank you for taking the time to read this. I am honestly enjoying learning c# and dotnet. I love maui and hope to continue developing in C# for many years! Here is an example of my code. This is what I am currently using. I hope to improve it by replacing it and using your package. As you can see I have a lot to learn :) <?xml version="1.0" encoding="utf-8" ?>

I was curious if I need to use an xmlns: statement in xaml? I have seen zero reference to any examples that incude that information. I have been wanting to use this project since it came out. As of now I have been unable to use it. My app has been mostly done for about 6 months and I would like to use the collection view to replace the built in one. But I have had zero luck integrating it.
