List of MSBuild built-in variables

These properties can also be defined by 3rd-party tools so to get the complete list I just use (in a C++ project for example): Properties -> Configuration Properties -> General -> then on the Output or Intermediate Directory drop down choose Edit... and you should see a list of all defined properties.

This seems like a pretty thorough list: Common macros for MSBuild commands and properties

Comprehensive lists from Microsoft Docs (New Docs):

• Common macros for MSBuild commands and properties
• MSBuild reference for .NET SDK projects

Comprehensive lists from MSDN (Legacy Docs):

• MSBuild reserved properties
• Common MSBuild properties
• Macros for Build Commands and Properties

Other useful lists:

• Well-known item metadata
• MSBuild special characters

First link shows the MSBuild property for project name:
