Hi Community. I have some questions about Loose Coupling Pattern in the Application Design. Is Loose Coupling Pattern The Best pattern for a TDD (Test Driven Development). Can you tell other Patterns in Application Design for TDD? Please can you bring some examples about Loose Coupling?
How many levels of separation do you want. Your WCF should be enough separation, I would have it call the DLL (which IS another program after all). There may be some security issues around you web server and the WCF communications that you may need to address.
Never underestimate the power of human stupidity
Some reasons for using a separate program.
- The dll is unstable and because of that it can cause an application exit.
- The dll is already encapsulated in an executable and in fact is easier to use that way or even can only be used that way.
- The dll is not structured for multi-threading and you want to use it in more than one thread.
The "alt" tag is meant to show text when the image isn't loaded, the "title" tag is meant for a description of an image on cursor hover. IE has been doing that wrong for many years, where Firefox follows W3C standards. A properly coded webpage should have both "alt" and "title" tags. So you can use Title For that Purpose
