Coverage is shown 0% for tested dll

Hi,

I have one ServerUnitTest dll in which I have written test methods to test Server.dll methods. There are 4 different dll refernced while running the tests. All tests are passed and when I saw the coverage report for Server.dll in the NCoverExplorer.

It show 0% coverage for Server.dll, I am wondering how it is possible becoz my Test dll is testing all methods in Server.dll

Help needed what I need to do.

Regd,

Amit
