Managing connectionstrings for multiple projects in same solution

Currently I have a larger Solution wit开发者_StackOverflow社区h different projects (A web application and a windows service,...). Since both applications use the same database, I created a connectionstrings.config file which is included by the web.confg (or app.config) using the connectsionstring's configsource attribute.

To maintain only one file, I did the following:

• One project contains the "real" connectionstrings file
• For all other projects that require the connectionstrings, I have added the existing connectionstrings.config file using the "add as link" option within Visual Studio.

To support different connectionstrings for different environments, I created environment folders that contain their own connectionstrings file. These files are used to replace the default ones during the buildprocess.

I wanted to know if you have other solutions for configuration values within different environments/projects?

If you are using Visual Studio 2010, you can use the config transform (video) feature.
