I am using entity framework 4 to create entities from DB.

I have 2 entity contexts to connect to db.
let's say context1 and context2

However, when I do the following steps, 
1. get data from context1
2. get same data row from context2
3. update same data row to context1
4. get same data row from context2

context2 doesn't change after updating in step 3.

I guess context2 cached the data. not getting data from db everytime.

how to fix it?

Thanks~
