CREATE ASYMMETRIC KEY Issues.

Hi

I created an sqlserverproject successfuly ( just has one CLR stored proc)

(http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnsql90/html/mandataaccess.asp)

i followed above steps to create the project.

when i tried to deploy the same to sql server  VS studio threw below error

CREATE ASSEMBLY for assembly 'MySqlServerProject' failed because assembly 'MySqlServerProject' 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. MySqlServerProject


then i realized i will have to either sign the assembly or create an asymmetric key. i decied to follow the latter. so i tried below t-sql statements in sql sever 2005

use master

GO

CREATE ASYMMETRIC KEY SQLCLRTestKey FROM EXECUTABLE FILE = 'C:myWorkSQL2005DBProMySqlServerProjectMySqlServerProjectinDebugMySqlServerProject.dll'

when i execute the above, SQL Server threw below error

The certificate, asymmetric key, or private key file does not exist or has invalid format.

What i am i doing wrong. please advise
