I am new to Enterprise library logging 5. I am trying to implement entlib5 for BizTalk. Can anyone please help me how to do this. There are less resources in internet.

I have installed entlib5 and configured BTSNTSvc64.exe with custom entlib config settings too.

I am getting this error like:

```
 The type LogWriter cannot be constructed. You must configure the container
 to supply this value."

```

with help of this link([Unity: The type LogWriter cannot be constructed](https://stackoverflow.com/questions/12950547/unity-the-type-logwriter-cannot-be-constructed)), I tried to resolve the error, but AddNewExtention method is not showing up in BizTalk Orchestration Expression box.

Probably I am doing something wrong in adding the entlib config to BTSNTSvc64.exe config. Can anyone suggest me how exactly it should be done?
