I'm creating WinForms application.
This application need to run custom scripts in may places like:

retrieving list of invoices
before adding invoice
before saving invoice
after saving invoice
before posting invoice
after posing etc.

etc.

I'm looking for script engine which simplifies this.
Features I need to embed into application are:

1. Syntax coloring script editor
2. Syntax check on script save
3. Executing scripts with error reporting
4. Passsing parameters to/from scripts
5. Allowing scripts to access application objects.
6. Maybe binding scripts to Winforms control events.

I read Ricks article about .net scripting but he covers only 3. and 4. poits above.

Any framework, idea, or sample code how to implement this ?
