Question Xamarin References like System.Web.Services or Mono.Data.Sqlite not working in MAUI

[4647t35c1v]

Hello, I'm trying to migrate a project from Xamarin.Forms to .Net MAUI (.Net 8).

With Xamarin.Forms I had some references inside the iOS and Android projects:
System.Data
System.Web.Services
Mono.Data.Sqlite

After migration I can find these under Dependencies – Assemblies with warning symbols.
Defining the namespaces is not working.

Can I no longer use these references under .NET MAUI?
I want to consume ASMX (SOAP) web services and use its CookieContainer property.
I would also like to access the local Sqlite DB with commands, data readers, etc.

Maybe someone can help me. Thank you!

Are there any messages shown when you hover over the warning symbols?

What happens when you remove the dependency and re-add the latest version as a dependency?

No, there are no messages.
I can't re-add the dependency.

With Xamarin.Forms I can go to Android or iOS Project, go there to "References", Right Click "Add Reference" - go there to "Assemblies". There are all the needed references like System.Data.SQLite.
Right Click on "References" - "Add Web Reference". Then I can insert a Web Reference to a ASMX Webservice (SOAP).

This is not possible in the migrated .Net MAUI projects or in a new empty .Net MAUI project.
There is no option "Add Web Reference". And when I try to add a reference, there is missing the "Assemblies" section on the left side of the Reference Manager Window.

I think with newer versions of projects, you need to add NuGet packages instead of adding references.

Thanks, that was a good tip...
Mono.Data.Sqlite can be replaced by NuGet package Microsoft.Data.Sqlite
ASMX (SOAP) web services client can be created as a WCF service reference.
