Whenever I add a new class to a Visual Studio (C#) project, I get the following usings automatically:
- using System;
- using System.Collections.Generic;
- using System.Linq;
- using System.Text;
Additionally, the following DLL references are added if they weren't there already:
- System.Core
- System.Data
- System.Xml
I'd like to prevent VS from doing this (except "using System" of course). Does any one know of a way to prevent this from happening?
Marc and Brian both have a good idea: create a new custom template that includes only the usings and references I want. With Export Template it's really simple to do so, and I'll be sure to do so for all sorts of specific items.
For general-purpose new classes (ie: what you get from the "Add->Class..." menu item in VS), here's what I did to achieve my goal:
- Find the appropriate template Zip. On my system it was located at C:\Program Files\Microsoft Visual Studio 9.0\Common7\IDE\ItemTemplates\CSharp\Code\1033\Class.zip
- Extract the zip file. This gives two files: Class.cs and Class.vstemplate
- Edit Class.cs to remove the undesired using statements. (I also changed the default class access modifier to "public" while I was here)
- Edit Class.vstemplate to remove the undesired
<reference>elements. - Rezip the files into the existing Class.zip archive
- Replace the cached template files with the updated versions. On my system, the files were located at C:\Program Files\Microsoft Visual Studio 9.0\Common7\IDE\ItemTemplatesCache\CSharp\Code\1033\Class.zip (a directory containing the old Class.cs and Class.vstemplate).
- I tried simply deleting this directory, expecting VS to rebuild the cache from the "original" source. This didn't work though; I got an error message saying that it couldn't find the files in the cache directory. Replacing the cached files worked well though.
- Restart Visual Studio
Now, whenever I add a new class, I get exactly what I want.
You can change your template files... either by editing the files in the install location, or by writing a class how you want it, and choosing Export Template. There is also a template add-in somewhere...
You can create your own customized item templates, see
for some details.
