A library can't directly use APIs absent from its compilation target. FSharp.Core 11 adds a net10.0 build alongside netstandard2.0 and netstandard2.1 so it can use modern .NET APIs without dropping older targets.
Target-specific APIs and behavior
The builds can expose different APIs and implementations. The targeting decision selects the modern target explicitly; it doesn't automatically follow the compiler's development target.
Which build your project uses
NuGet selects the nearest compatible asset for each project target. .NET 10 and later projects can select lib/net10.0/FSharp.Core.dll; older compatible targets select a .NET Standard asset.
To diagnose availability:
- Check the resolved FSharp.Core package version.
- Inspect the selected compile and runtime assets in
obj/project.assets.json. - Check the runtime that executes the application, not only its reference assemblies.
<LangVersion>preview</LangVersion> enables compiler behavior. It doesn't add missing Core members, select a different package asset, or provide runtime support.
Examples of the differences
| Area | Availability in Core 11 |
|---|---|
| ValueTask helpers and related overloads | Available in netstandard2.1 and net10.0, not netstandard2.0. |
Bounds-preserving Array2D.map, mapi, and copy |
The net10.0 build uses a newer .NET allocation API; .NET Standard builds retain their fallback. |
| Runtime-async return intrinsics | Exposed by the net10.0 build; compiler, language, reference, and runtime requirements also apply. |
For details, see Async and task functions and Array2D and Native AOT. Ordinary Async/Task helpers and print/printn are available across all three builds.
F# Interactive and asynchronous disposal
F# task expressions already support IAsyncDisposable resources in compatible compiled projects. The F# 11 packaging fix supplies the modern Core build to F# Interactive so equivalent use and use! code also works there. Update the toolset, not only an application's package reference.
Runtime async is a separate runtime contract
The Core build's net10.0 target doesn't establish runtime-async support. Follow the separate compiler, reference, and runtime requirements in Runtime async experiments.
