CS1021: Error ambiguous between System.Link.Queryable and System.Link.Async.Queryable -- Is there away to use both in same method; or to exclude System.Link.Async?

Description

Added NuGet package System.Link.Async; for an Async Repository. Worked great.
But, now all the non-Async methods in repository are saying Ambiguous reference because of previous System.Link.
Can remove "using System.Link", but obviously, the non-async method link statements will throw errors.

In otherwords, your nuget package is stepping on the System.Link namespace.

Using EntityFramework database _contect has similiar issue.

The Async Link is awesome, just would like to use it with the rest of my existing applicaiton.

Repro steps

Please provide the steps required to reproduce the problem

1. Step A

2. Step B

If possible then please create a git repository with a repro sample or attach a zip to the issue.

Expected behavior

Please provide a description of the behavior you expect.

Actual behavior

Please provide a description of the actual behavior you observe.

Known workarounds

Please provide a description of any known workarounds.

Start by building a minimal C# example that references System.Link.Async alongside System.Link and uses both synchronous and asynchronous repository methods. The issue does not name a repository file or test; done would require a confirmed reproduction and a documented compatibility solution or a clearly scoped package change.
