unsafe code error :
----------------------
CSHarp I got the folloing error :

Error :Build with unsafe code problem
Solution :

Go to Project -> Properties and then to the Build Tab. Ensure for all Configurations (on the top of this page) the Allow unsafe code check box is checked. If it is not checked for one of the configurations and Team Build is setup to build that configuration then your build will fail with this error.
