.NET 8 项目运行失败

描述

在 2023.12 或更低版本的 Robot 上执行使用 Studio 2024.2 构建的 Windows 或跨平台流程时将失败，并显示以下错误：“远程异常：NU1202：包 <package_name> <version> 与 net6.0-windows7.0（.NET CoreApp，版本 = v6.0）不兼容。包 <package_name> <version> 支持：net8.0-windows7.0（.NET CoreApp，版本 = v8.0）。”

潜在问题

NuGet tries to resolve a package for .NET 6, whereas your automation was built using .NET 8. Such forward compatibility is not supported.
