.NET 8 projects fail to run
Description
Executing a Windows or a cross-platform process built using Studio 2024.2, on a 2023.12 Robot version or lower, fails with the following error: "RemoteException: NU1202: Package <package_name> <version> is not compatible with net6.0-windows7.0 (.NETCoreApp,Version=v6.0). Package <package_name> <version> supports: net8.0-windows7.0 (.NETCoreApp,Version=v8.0)."
Potential issue
NuGet tries to resolve a package for .NET 6, whereas your automation was built using .NET 8. Such forward compatibility is not supported.
Solution
Upgrade your Robots to version 2024.2.
