The IncludeSourceFiles property of the ProjectConfig class in the Sandbox.DataModel namespace determines whether all source files should be included in the project configuration. When set to true, the source files are included; otherwise, they are not.
To use the IncludeSourceFiles property, you can access it directly from an instance of the ProjectConfig class. This property is a boolean, so it can be set to either true or false depending on whether you want to include source files in your project configuration.
// Example of setting the IncludeSourceFiles property
// Create an instance of ProjectConfig
ProjectConfig config = new ProjectConfig();
// Set IncludeSourceFiles to true to include all source files
config.IncludeSourceFiles = true;
// Check if source files are included
bool areSourceFilesIncluded = config.IncludeSourceFiles;
// Output the result
// Note: Avoid using Console.WriteLine in Sandbox
// Instead, use logging or other appropriate methods
// Log.Info($"IncludeSourceFiles: {areSourceFilesIncluded}");
