Creating separate T4Scaffolding.Core package with base functionality

description

I'm building scaffolding packages for building Silverlight, WinRT, Windows Phone business applications and I need base T4Scaffolding package, that have the base classes from T4Scaffolding package and can be installed on Silverlight/WP/WinRT projects.
Current T4Scaffolding conatins some base templates for generating EntityFramework dbcontexts and requires asssemblies referenced in the project where T4Scaffolding is installed.
I have modified T4Scaffolding and created T4Scaffolding.Core package that works with Silverlight and RIA Services client entities. I want to make the project public so anyone can use the package and extend the templates. I can provide list with changes and steps that should be made for creating the core package.

Hi

Following your suggestion I've spiked up a candidate implementation in the "WithT4Scaffolding.Core" branch.

Could you have a look at this, try it out, and let me know if that would meet your needs? My main focus is elsewhere right now, so I'm not able to dig too deep into it. If by any chance you are able to spend some time testing that the updates work in all the main cases, e.g.:
  • Installing MvcScaffolding from scratch into an MVC 3 project and using it in both C# and VB projects
  • Updating from an older version of MvcScaffolding+T4Scaffolding and using it
  • Installing T4Scaffolding from scratch into an MVC 3 project and using it in both C# and VB projects
  • Updating from an older version of T4Scaffolding and using it
  • Installing T4Scaffolding.Core into a non-web project and using it
... then that would help me justify merging this branch into master and publishing T4Scaffolding.Core to the public feed. No worries if you are unable to do that, but it may be a while before I can do!

Thanks for the suggestion

Hi, @trustorm

I'm using T4Scaffolding.Core.1.0.0 for a few weeks now and it's working nice in silverlight client application.
Here is the package, I've build for myself with a few modification to work with RIA Services:
https://skydrive.live.com/redir.aspx?cid=bf361213901d682b&resid=BF361213901D682B!1842&parid=BF361213901D682B!1841

Please try that package and check if it works for you. If it does not work make sure you have installed last Nuget manager.

Todor.

I've tested T4Scaffolding and MvcScaffolding with T4Scaffolding.Core:
Here are test cases and results:


Date: 21.04.2012 21:00

Performed tests on packages T4Scaffolding and MvcScaffolding with T4Scaffolding.Core.1.0.0.0
  1. Installing MvcScaffolding with T4Scaffolding.Core from scratch into an MVC 3 project and using it in both C# and VB projects

Summary:
  • Installing fresh MvcScaffolding and T4Scaffolding with T4Scaffolding.Core in VS2010 (nuget 1.6 and 1.7) MVC Project is working
