I just released version 1.7.0 of generator-nullfactory-xrm. This release includes a lot of defect fixes, dependency version upgrades and refactored code.
Feature #37: Added ability to upgrade tooling PowerShell scripts via the generator.
Run yo nullfactory-xrml:tooling
Feature #12: The generated *.csproj files now have unique identifiers. This should avoid any potential conflict between projects.
Feature #35: .gitignore file updated to be compatible with nested "standard project structure". (see https://gist.github.com/davidfowl/ed7564297c61fe9ab814).
Fixed #34: Pull-CrmSolution.ps1 now downloads the zip file to a temporary file location before extraction.
Fixed #36: solution sub-generator now creates mapping file as expected.
