SQL CLR Integration With Visual Studio 2005/2008

Dear all,

I am trying to integrate Sql Clr with Visual studio 2005, but i am getting the following error when i try to deploy the solution:



CREATE ASSEMBLY for assembly 'SQLCLRIntegrationDemo' failed because assembly
'SQLCLRIntegrationDemo' is not authorized for PERMISSION_SET = EXTERNAL_ACCESS.
The assembly is authorized when either of the following is true: the database owner (DBO)
has EXTERNAL ACCESS ASSEMBLY permission and the database has the TRUSTWORTHY database
property on; or the assembly is signed with a certificate or an asymmetric key that has
a corresponding login with EXTERNAL ACCESS ASSEMBLY permission. If you have restored or
attached this database, make sure the database owner is mapped to the correct login on
this server. If not, use sp_changedbowner to fix the problem. SQLCLRIntegrationDemo


I have even set the Permission to External in the Project --> Properties --> Database tab.
But still i am getting the above solution while deploying the solution.

One of the blogs suggested that the checkbox beside 'Trustworthy Database' should be checked. But i dont see any checkbase in the database tab of the Project properties.

Any help would be appreciated.

Thanks in advance.

Regards,
Sunny.
