VScode 中的 Unity intellisense 不工作，Omnisharp 给出多个错误和警告

Question

所以，我对编码有点陌生。 我正在 Unity 中制作游戏，我刚开始编写脚本。 不幸的是，VScode 不适合我。 我已经在 VScode 中安装了最新的 C# 扩展，.NET 版本是 6.0.401。

每当我启动 IDE 时，我都会收到一条错误消息

Some projects have trouble loading. Please review the output for more details.
Source: C# (Extension)

当我检查 output 时，它是这样说的：

此外，智能感知不起作用，所以我必须手动输入内容。 我不够理智或不够聪明，无法尝试修复它。 如果需要更多信息，我会提供。

Answer 1

我不知道为什么这还没有回答，但为了尽可能简单，unity 不使用最新版本的 .net 但它仍然会引导您到最新的链接，但它写在它正在寻找的日志中版本 4.7.1 从这里下载我的兄弟（下载 devPack 然后重新启动你的电脑） https://do.net.microsoft.com/en-us/download/do.net-framework.net471

Answer 2

您需要 Dot.net 开发包版本 4.7.1 （不是运行时版本），VScode 才能与 Unity 一起正常工作。

确保在安装开发包时关闭 Vscode 和 Unity。
