SharpCrafters has created PostSharp Toolkits, an open source product that provides some useful pre-built aspects for common cross-cutting concerns. Currently, the only toolkit so far is the diagnostics toolkit, which includes aspects for logging, exception handling, etc.

You can find PostSharp Toolkits on Github. If you want support for PostSharp Toolkits, you can submit questions or suggest features in the PostSharp Toolkits support thread.

(It's being open sourced in order to get a shorter feedback loop, but most likely they aren't going to take unsolicited patches).
