Deploy Failed : CLR Trigger

问题

Am trying to deploy my CLR Trigger built on .Net 4.0 but changed the target framework to 3.0 but i got the below error message.

------ Deploy started: Project: ServiceClient, Configuration: Debug Any CPU ------ Build started 18/01/2012 2:16:24 PM.

To resolve this issue, open the properties for the project, and change the .NET Framework version.

回答1:

It is clearly stated - it wants System.ServiceModel assembly, which is not supplied. Try to deploy this assembly (and may be some others) to sql server first

And try to move your static fields into the body of trigger as local variables.

May be if you mark your assembly as UNSAFE and database as TRUSTWORTHY - it will work without these modifications
