T4 text template is mixture of text block and control logic that can generate the file in Visual Studio. First time I noticed text templates when I was working with Entity Framework. T4 text template is one of the best hidden feature of Visual Studio. It can help you to generate the file on the fly and automate the task. You can even generate the .net classes. You can get more details about T4 text templates here.
As a developer you need SharePoint column internal names while writing code for various operations. You can get the internal name for a column by browsing to the List Settings > Edit Columns. Column internal name is encoded as querystring "Field" in URL. For example:
I wanted to generated C# utility class using T4 text template which contains Web, Lists and columns related information. Following is the template I use to get Web, Lists and Columns related information while SharePoint development:
Above template generates the following class:
Now you can using intellisense to get List, Column Id .
Simply add "SharePointObjects.tt" file to your project in Visual Studio. Update the Site url and save. It will generate the C# class.

Now you can using intellisense to get List, Column Id .
Simply add "SharePointObjects.tt" file to your project in Visual Studio. Update the Site url and save. It will generate the C# class.
