.Net 10 Upgrade

[rob phoenix]

Hi Govert 

Will Excel-DNA support the upcoming LTS .Net 10 upon its release? 

Thanks

Hi Rob,

 

You can test Excel-DNA v1.9.0 with the pre-release versions of .NET 10 using an explicit RuntimeFrameworkVersion property like this:

    <TargetFramework>net10.0-windows</TargetFramework>

    <RuntimeFrameworkVersion>10.0.0-preview.7.25380.108</RuntimeFrameworkVersion>

 

For the release version the extra property should not be required.

Hello,
I've been updating and testing our tools to use .NET 10 and it works great so far. 

But, before going in PROD, is the support for .NET 10 still in "preview" with the official v1.9.0 release?
The Release note (from July https://groups.google.com/g/exceldna/c/GEgjAe6o3h8/m/t7k8ExHzAwAJ ) says "preliminary support for .NET 10".

I'm not sure if that comment was for :

• the v1.9.0-rc3 release; OR
• the fact that, in July 2025, .NET 10 was only available in preview; OR
• v1.9.0 does not fully support .NET 10 yet.

Thank you very much for the hard work you and the ExcelDna teams put in to this gem!

Hi Jean-Francois,

 

I’ve not heard of any specific problems related to .NET 10, and there is nothing more we’re planning to do on the Excel-DNA side related to that runtime release.

The note was reflecting the fact that .NET 10 was in preview, and at the time we had implemented support but not had any feedback yet.

I’d say if you’ve tested a bit and you’re happy with the configuration, there’s nothing to wait for before a ‘release’ on top of .NET 10.

 

If you run into any issues, please let us know.

 

Regards,

Govert
