Compiling a .NET 8 based DLL file

[Maj7510]

Hi,

I just want to compile an Ironpython command as a DLL file targeting runtime targeting .Net 8, but when using ipy command it only targets .Net 4.8.
So I appreciate it if you could let me know how I can create a .Net 8-based DLL file or run ipy under the .Net 8.

Thank you so much in advance

By default the .NET Framework 4.8 version ships for the Windows install.
You can compile from source to target another version of .NET

@slozier what's the reason for not targeting .NET 8 in the production Windows version?

The .NET 8 version is available to install as a .NET tool and also included in the zip package on the release page. This is all noted in the installing docs.

As for why the msi does not come with the .NET 8 version, it is because the expectation when running ipy commands is the availability of the full runtime. I imagine we could do like PowerShell and ship the full runtime, but this is not something I have had the time (or interest) to look into.

Relating to the original question, I had initially understood it to be about compiling DLLs, for example using ipyc, although now that I read it again it's unclear. Anyway, if this is the question, the reason we can't compile .NET 8 DLLs using IronPython is that .NET 8 does not provide the APIs that are currently used to do this.

What APIs are being used?

IKVM.Reflection?
