Can't install SwarmUI

[Tenofas]

I have been using StabilityMatrix a lot, with Fooocus, OneTrainer, InvokeAI, SD.Next, even ComfyUI (just once, it's so weird!) runs fine, but I can't install SwarmUI.
There seems to be a problem with the .NET version StabilityMatrix installed in its Assets. It says I have the 7.0.405, but SwarmUI needs the v 8.0.
This is the error msg (sorry, it's in Italian, but I guess it's easy to understand):

Versione di MSBuild Ł17.7.4+3ebbd7c49 per .NET
Individuazione dei progetti da ripristinare...
E:StabilityMatrix\Data\Assets\dotnet\sdk\7.0.405\Sdks\Microsoft.NET.Sdk\targets\Microsoft.NET.TargetFrameworkInference.targets(160,5): error NETSDK1045: la versione corrente di .NET SDK non supporta .NET 8.0 come destinazione. Impostare come destinazione .NET 7.0 o una versione precedente oppure usare una versione di .NET SDK che supporta .NET 8.0. Scarica .NET SDK da https://aka.ms/dotnet/download [E:\StabilityMatrix\Data\Packages\SwarmUI\src\SwarmUI.csproj]

and it continues:
Could not install StableSwarmUI (StabilityMatrix.Core.Exceptions.ProcessException: dotnet8 with args [build src/SwarmUI.csproj --configuration Release -o src/bin/live_release] failed with exit code 1:

How can I update to .NET 8.0 (that I have already installed in my PC, under windows 11) in StabilityMatrix?
Any hint?

Thanks in advance.
