What happened, and what did you expect?

What happened, and what did you expect?

A valid C# 14 extension declaration can cause the containing .cs file to not be indexed at all.

Minimal example:

using System;
using System.Collections.Generic;
using System.Linq;

namespace DemoApp.Domain.Test;

public static class NumberExtensions
{
extension(IEnumerable numbers)
{
public int SumPositive() =>
numbers.Where(number => number > 0)
.Aggregate(0, static (running, next) => running + next);
}
}

After indexing the repository, this extension method is not present in the Codebase Memory graph at all.

Expected result

The extension method should be indexed normally.

Reproduction

1. Create a .NET project using C# 14.
2. Add a file containing:
   using System.Collections.Generic;
   using System.Linq;

namespace DemoApp.Domain.Test;

public static class NumberExtensions
{
extension(IEnumerable numbers)
{
public int SumPositive() =>
numbers.Where(number => number > 0)
.Aggregate(0, static (running, next) => running + next);
}
}
3. Run a full repository index.
4. Search the graph for: SumPositive

Actual Result:

The SumPositive is not indexed / does not appear in the graph.

Confirmations

• I searched existing issues and this is not a duplicate.
• My reproduction uses shareable code (a dummy snippet or a public OSS repository), not proprietary code.
