Hi,

are there any plans to support .NET 5 / .NET Core?
It would be very nice to be able to develop office add ins using .NET 5 / .NET Core.

Thanks!

Hello David,

.NET Core is about .NET development on non-Windows platforms. None of these platforms supports things essential for developing Office extensions on Windows Desktop: COM and registry. A manifestation of this difference is the "Register for COM interop" check box on the {project Properties} | Build tab: the check box is disabled if the project targets .NET Core.

Not exactly. .NET Core is about multi platform development, including Windows.
But that doesn't really matter anymore anyway:
https://devblogs.microsoft.com/dotnet/introducing-net-5/

Microsoft will replace both .NET Core and the .NET Framework with .NET 5, which is essentially the successor of both the .NET Framework and .NET Core.
Which means that in the long run we will have to migrate to this .NET 5.

There are already many nuget packages wich do not target the "classic" .NET Framework anymore.

So the big question is will there be any support for Office Add-Ins (and hopefully add-in-express) for .NET 5?

Thanks!

Hello David,

Thank you for this info. There's no answer at this stage. Let's wait for the first preview of .NET 5 which is expected in the first half of 2020.
