Is there a solution for introduce member support IntelliSense?

[yumikou]

Before using Metalama I use SourceGenerator for class add some new members , It can add a partial class by atrribute, when i writing code, i can access just added properties or methods by IntelliSense.

Is it possible metalama to support this feature, or can I introduce a member in a partial class like SourceGenerator?

Yes, this is supported. Metalama uses source generators to implement this feature.

Thanks for the reply, Later I found, Sometimes I can see this partial class in Metalama.Framework.CompilerExtensions.MetalamaSourceGenerator in Project Analyzers.
Like this:

/// <generated>
/// Generated by Metalama to support the code editing experience. This is NOT the code that gets executed.
/// </generated>
namespace MyLibrary
{
    partial class TestClass
    {
        public static readonly global::System.Windows.DependencyProperty CustomProperty;
    }
}

At this time IntelliSense works well.

But sometimes, it shows "this generator is not generating files" in Analyzers, I don't know what is causing this and I don't have any modifications.

There may be some bugs. In this case, the best is to enable logging for the RoslynCodeAnalysisService process as described in https://doc.metalama.net/troubleshooting/creating-logs, and to look for an exception when the problem happens - and report it.
