Install Code Map and Live Dependency Validation
Note
To create and edit code maps, you need Visual Studio Enterprise edition. However, in Visual Studio Community and Professional editions, you can open diagrams that were generated in Enterprise edition, but you cannot edit them, see Version support for architecture and modeling tools.
To create a code map in Visual Studio Enterprise, first install the Code Map and Live Dependency Validation components:
Open Visual Studio Installer. You can open it from the Windows Start menu, or within Visual Studio by selecting Tools > Get Tools and Features.
Select the Individual components tab.
Scroll down to the Code tools section and select Code Map and Live Dependency Validation.
Select Modify.
The Code Map and Live Dependency Validation components begin installing. You may be asked to close Visual Studio.
