如何在 VS 2017 中向 ASP.NET Core 項目添加類圖？
我按照如何：將類圖添加到項目中進行操作，但是在安裝 ClassDiagram Visual Studio 組件後，我的 ASP.NET Core 項目中沒有“類圖”模板（我在安裝組件後重新啟動了 Visual Studio）：

在這裡回答得很好，這是一個已知問題（投票讓 MS 修復它！）
作為一種解決方法，從 New File 對話框創建一個名為
Diagram.cd（替換Diagram為您的選擇）的純 XML，右鍵點擊該文件並選擇Open With…，然後選擇XML (Text) Editor，然後將其內容替換為以下內容：<?xml version="1.0" encoding="utf-8" ?> <ClassDiagram MajorVersion="1" MinorVersion="1"> <Font Name="Segoe UI" Size="9" /> </ClassDiagram>然後關閉保存它的文件。當您正常重新打開它時，它現在應該可以工作了。
