Ix.NET v7.0: .NET 10 and LINQ for IAsyncEnumerable<T>

[idg10]

Ix.NET v7.0 is now available.

The entire reason for this release is to accommodate the fact that .NET 10.0 now includes an implementation of LINQ to IAsyncEnumerable<T>. Prior to .NET 10.0, if you wanted LINQ for IAsyncEnumerable<T> you had to use System.Linq.Async, which was part of Ix.NET (which lives in this repo).

We have had to modify Ix.NET's System.Linq.Async to get out of the way of the new .NET 10.0 implementation of this functionality.

Note that .NET 10's new support for this is also available on older runtimes via the System.Linq.AsyncEnumerable package. If you update your System.Linq.Async (Ix.NET) package reference to v7, this will automatically bring in a reference to .NET's new System.Linq.AsyncEnumerable, and any code that was previously using our (Ix.NET) implementation of LINQ will, once recompiled, now be using .NET 10's.

We maintain binary compatibility. (The System.Linq.Async package ships separate reference and runtime assemblies. The whole legacy API remains available in the runtime assemblies to provide binary compatibility. But we're removed our old LINQ for IAsyncEnumerable<T> implementation from the public API defined in our reference assemblies.)

We will be marking System.Linq.Async as deprecated at some point. You should stop using it as soon as possible.

.NET's System.Linq.AsyncEnumerable didn't re-implement everything in Ix.NET's System.Linq.Async. We've moved the relevant methods into System.Interactive.Async (which you will automatically get a transitive reference to if you continue to use System.Linq.Async.)

See https://endjin.com/blog/2025/11/ix-v7-dotnet-10-linq-iasyncenumerable for a much more detailed description of what has changed.
