Known Issue with Models Builder

ModelsBuilder in PureLive mode, watches for changes to DataTypes and DocumentTypes, and rebuilds its code models as needed. this means that every time uSync updates a DataType or DocumentType ModelsBuilder will rebuild models. If to many changes happen in quick succession then IIS can restart your site mid import which can cause issues.

We don't like to tell you how to setup your site. One of the principles of uSync is it works however you want to work. But at the moment it is our recommendation that your don't use PureLive mode when deploying sites via uSync.

We are working on finding a workaround for this, and will update you when we have one. You can track our progress over on GitHub https://github.com/KevinJump/uSync8/issues/18
