A further note on Dmitry s 2017 answer  I opened up   C  Program Files  x86  Microsoft Visual  Studio 2017 Community MSBuild Microsoft VisualStudio Managed   Microsoft CSharp DesignTime targets    and went to the  lt ProjectCapability gt  element  I already had this    lt ProjectCapability Include                             CSharp                            Managed                            ClassDesigner         gt    with ClassDesigner already there  and yet I was still unable to drag items to my hack-made Diagram cd using the XML editing method Dmitry mentioned       Manually create text file  say MyClasses cd with following content      lt  xml version  1 0  encoding  utf-8   gt   lt ClassDiagram MajorVersion  1   gt  MinorVersion  1  gt   gt       lt Font Name  Segoe UI  Size  9    gt   lt  ClassDiagram gt       But when I took off the semicolon off  ClassDesigner  in that element then reopened Visual Studio  voila  I was able to drag classes from my Solution Explorer to my Diagram cd window    So in conclusion  this element in Microsoft CSharp DesignTime targets worked     lt ProjectCapability Include                                 CSharp                                Managed                                ClassDesigner    gt    I am using VS 2019  version 16 1 5

You need to install    Visual Studio extension development    workload and    Class Designer    optional component from the Visual Studio 2017 Installer to get the feature   See  Visual Studio Community 2017 component directory  But this kind of item is not available on all project types  Just try for yourself    In a Console App   NET Framework  is available  In a Console App   NET Core  is not available    I couldn t find more info on future availability also for  NET Core projects

Noticed this in the beta and thought I had a bad install  The UI elements to add new Class Diagrams were missing and I was unable to open existing   cd Class Diagram files in my solutions  Just upgraded to 2017 and found the problem remains  After some investigation it seems the Class Designer component is no longer installed by default    Re-running the VS Installer and adding the Class Designer component restores both my ability to open and edit Class Diagrams as well as the UI elements needed to create new ones

Woo-hoo  It works with some hack   According to this comment you need to    Manually edit Microsoft CSharp DesignTime targets located in C  Program Files  x86  Microsoft Visual Studio 2017 Community MSBuild Microsoft VisualStudio Managed  for VS Community edition  modify path for other editions   append ClassDesigner value to ProjectCapability  right pane   Restart VS  Manually create text file  say MyClasses cd with following content    lt  xml version  1 0  encoding  utf-8   gt   lt ClassDiagram MajorVersion  1  MinorVersion  1  gt       lt Font Name  Segoe UI  Size  9    gt   lt  ClassDiagram gt     Bingo  Now you may open this file in VS  You will see error message  Object reference not set to an instance of object  once after VS starts  but diagram works   Checked on VS 2017 Community Edition  v15 3 0 with  NETCore 2 0 app project     GitHub issue expected to fix in v15 5
