# https://taskfile.dev

#Called by the vnbuild system to produce builds for my website
#https://www.vaughnnugent.com/resources/software

#This taskfile performs the build operations for a module, it handles
#git code updates, msbuild on solutions, and sleet NuGet feed pushes.

#this file must be in the same directory as the solution file

#NOTES: Since CI project is pulled from the module root, MODULE_DIR is used instead of PROJECT_DIR
