Ribbon with .Net 8

[Yaume2]

Hello,
I've got a project in .Net 8.
I've tried lot of methods to add a buton on ribbon.
But i have "The required .NET Desktop Runtime 6.0.2 x64 is incompatible with the runtime 8.0.18 already loaded in the process."
What can i do ?

Oh i found it. Just add RuntimeVersion="v8.0" on root node of dna file.
Sory guys.
