The master branch is for Visual Studio 2019 and later and is the default branch for all current and future development. In order to build the projects you will need Visual Studio 2019 or later.
.\Source - This folder contains the source code for all of the projects.
.\Docs - The Sandcastle Help File Builder project used to manage the extended documentation comments provider project's documentation.
.\Deployment - This folder contains the deployment resources (the installer and all related files) generated by building the projects.
To build the projects, open the solution file (*.sln) for your version of Visual Studio (currently 2019 or 2022) found in the Source\ folder and build it. You can also run the MasterBuild.bat script from a command prompt to build the projects.
In order to debug the projects:
Set the ExtendedDocCommentsProvider project as the default project and then open its project properties.
Go to the Debug category.
For the Start Action option, set it to Start external program, click the "..." button after the text box, navigate to the installation folder for your version of Visual Studio and select the devenv.exe file in that folder (i.e. C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\Common7\IDE\devenv.exe).
For the Command line arguments option, enter the value /rootsuffix Exp.
When you run the project, it should start a new instance of Visual Studio using the experimental instance settings.
