Best practices: C# Extension methods namespace and promoting extension methods

Question

I know there exists already a post, describing nearly the same, but I think mine is a bit different.

What I would like to know is how you organize your extension methods

Answer 1

We put everything into the same Namespace and Class, however we use partial classes to keep them organized.

For example:

ExtensionMethods-String.cs

ExtensionMethods-DataObject.cs

ExtensionMethods-Debug.cs

...etc all have partial classes...
