Feature Request: Customize Method Selection in MethodDecoratorMap Without Using Attributes

[mesutcakir]

Hello,

In our project, we want to use MethodDecoratorMap or a similar structure and choose the method here with a more dynamic approach instead of using attributes. Currently, we need to add an attribute like [Decorate(typeof(MyDecorator))] to each service method. However, instead of this alternative, methods are automatically selected and the decorator is displayed based on a certain standard of criteria (e.g. all methods marked as public and virtual).

Recommended Solution:
As a suggestion, I suggest adding a mechanism in MethodDecoratorMap or similar structure where method selection can be made via a user-supplied function or lambda description. This will allow us to automatically select methods and attributes according to a given set of rules, rather than manually changing attributes, especially in large projects.

An example usage scenario:

services.AddMethodDecoratorMap(config => {
      config.IncludeMethods(method => method.IsPublic && method.IsVirtual);
});

This feature provides great convenience in our project and other projects that work similarly. It will allow users to have a more flexible and dynamic pace, while also making the code easier to read and maintain.

Thank you for your support and contributions.
