由於內部錯誤，“Diagnostic analyzer runner”目前不可用

Question

我使用的是 Visual Studio 2022 (17.4.4)。 這是一個 .NET 6 C# 項目。

在我的項目上運行代碼分析時，我立即收到消息““項目名稱”的代碼分析已完成”。 不顯示代碼分析警告或錯誤。

然后，當我讓 Visual Studio 打開幾分鍾（什么都不做）時，2-3 分鍾后會出現一個錯誤欄：

“由於內部錯誤，功能‘診斷分析器運行程序’當前不可用。[顯示堆棧跟蹤]”

當我點擊“顯示堆棧跟蹤”時，我得到了一個堆棧跟蹤（附在這篇文章的底部）。

我該如何解決這個問題或進一步調查？

當您遇到這樣的消息時，它就是一個錯誤。 因此，您可能無能為力。 此類錯誤應報告給 Microsoft。

此錯誤已報告https://github.com/do.net/roslyn/issues/50496

您將不得不等待修復。
