(Uno.Extensions) Would like to Contribute Storage Doc Pages in uno.extensions, but the setup in the appHost is not working as expected

[DevTKSS]

Added this discussion here because all requests and issues filed to that Uno.Extension topic keept unanswered there from what I seen

I did research the uno.extensions.Storage and Storage.UI Namespace in the repo and tryed to add ".UseStorage()" on different places on my app.xaml.cs file, because the docs seem to not tell how to do that. Okay, so I would have wanted to understand it from your extensions repository, looked up the ServiceCollectionExtensions.cs and HostBuilderExtensions.cs file in there and would like to help out with Contribute to the Doc files, to add this missing content there for all others.
My Problem with that:
from what I read in that mentioned files, it would mean similar approach like add it like this to the host.Configure( ... .UseStorage((context,services) => services but the Options visible on the lower part of this HostBuilderExtensions file:

.AddFileStorage and .AddKeyedStorage are not available in my application to be used.

[x] UnoFeatures includes Storage
[x] Added the Namespace Uno.Extensions.Storage to my global usings (might be additionally and not needed, because its greyed out as not used
[x] tryed different places to add the .UseStorage(...) none let me see some of this Methods

Possible issue:
Although I did add the feature this only added Uno.Extensions.Storage.WinUI, but looking at the repo, there is none Namespace that is named Storage.WinUI, its Storage.UI which should be added from the uno.sdk in my opinion. but the "UseStorage" option is available in general.

Could someone check that and give me feedback if there is any issue I am making and where that can be configured? looked into the UWP Samples "FileAccess" that is not used in the uno.extensions.storage and also not in the .UI Namespace and also not added into the Packages of my app via the sdk.

Hi @DevTKSS!

The .UseStorage() extension method should be automatically included as part of the CreateDefaultBuilder() in your App.xaml.cs. You can see this here.

But you can always add the method yourself if you wish by setting it inside of the .Configure(host => host

I have attached a sample app that uses the Storage feature and has the IStorage implementation injected into the MainModel. We then read file info as part of a button click as can be seen by the LoadStorageData method in the MainModel.

Before clicking

After clicking

Sample app: UnoApp124.zip

As for the .AddFileStorage() and .AddKeyedStorage() methods, these are internal extension methods that are not accessible from your application code. If you wish to register a different implementation of IStorage, you would need to provide a custom Action<HostBuilderContext, IServiceCollection> as part of the configure parameter of the UseStorage method

Hopefully that explains a bit more! I do see that the Storage documentation does not include details concerning UseStorage() and using the IStorage interface: https://platform.uno/docs/articles/external/uno.extensions/doc/Learn/Storage/StorageOverview.html)/StorageOverview.html

I see this issue was created in the Extensions repo and you have commented on it: unoplatform/uno.extensions#2630

If you are up for it, I would be happy to look over and review a PR from you that would add these details to the official documentation!

Hey @kazo0 thank you for your reply!
From the "AddKeyedStorage" Method name and the passwordvault class (internal) i found in the repo files, I would have an additional question to this.
As you might know, the dotenv vault package is kind of popular in vs code using applications for example in case we use http requests. Correct me if i am wrong, but I did not see any option to store such secrets like the api key we learn about in the http and authorization extensions/features of uno. Maybe we could following up to that general storage usage for e.g. after-runtime usecase get anything working or if not do-able with that, maybe add such implementation for Enhancement? Is that realistic?
Yes, i know that there is aws and azure, but as they also told in their homepage and package description, its easyer for some bad guys to interrupt web communication than encrypt files. Also additional, it might be especially for smaller applications that are not wanting to use this services at all but want to consume data, a great thing to can use.

@kazo0
is there also a way to actually get the data defined in the appxmanifest file readable in the application? most likly that will be in the app.xaml.cs somewhere. for example if there would be some kind of about page in the application which is quite normal, if we could get this information automatically up to date. I think in vb.net (framework) with winforms I got there with My.Settings.Application or similar, but heared in c# we are wanting to not use reflection isnt it? would you type that information into the appsettings?
