c# - 使用 .Net6 Windows 10 在 Visual Studio Code for OmniSharp 上出错

Question

您好，我通常使用 Visual Studio 创建项目，但建议尝试使用 VS Code 进行 .Net6 项目

我在编译器中遇到了一些错误

它以“C# extension Some projects have trouble loading. Please review the output for more details”开头

这些是错误

我不确定为什么会这样，搜索后我发现有些人说 OmniSharp 与 .net6 不兼容

如果有人有任何解决方案，请帮助，谢谢。

尝试将 VS Code 和 Omnisharp 更新到最新版本。如果没有帮助 - 安装 VS 2022 并再次尝试运行 VS Code。
