Integration with ncover

I'm trying to use TypeMock together with NCover

When I run simple NAnt script that starts typemock and runs ncover (from typemock documentation), the tests (including those dependent on TypeMock) are executed successfully , but then I get

[ncover] ***************** Exception *****************
[ncover]
[ncover] -- Top-level exception (System.Exception)
[ncover] No data was collected.
[ncover] -- Stack Trace
[ncover] at NCover.Framework.ProfilerDriver._GetCoverageData()
[ncover] at NCover.Framework.ProfilerDriver.Execute()
[ncover] at NCover.ConsoleMain.ConsoleMain.Main(String[] args)
[ncover]

BUILD FAILED

c:TeamCityTools ant-0.86-beta1in est1.build(43,6):
External Program Failed: C:Program FilesNCover\NCover.Console.exe (return code was 20000)


What am I doing wrong?


NAnt script:
