Referencing a CLR DLL in a Custom Task

Is there a way you can reference a prebuilt CLR function in a custom dataflow task?

The CLR and the custom dataflow task are one in the same. The reason that I'm designing the custom task is that I find that it's time consuming to make a call to the database to retrieve a function to work on something that's already in memory. Also, another reason is that if the code needs to be updated, it doesn't have to be done in 2 places allowing for less confusion.

I tried adding a reference to the CLR function in my SSIS dataflow task, but when I try running it in SSIS, I get the error saying it cannot use a SQL CLR defined task in the package which I believe is due to this reference in the CLR code:

[Microsoft.SqlServer.Server.SqlFunction]
public static string toCase(string text, string caseType)

Is there a way to circumvent the [...SqlFunction] line of code when the DLL is referenced by an SSIS dataflow task, or do I just have to deal with having 2 copies of the same code?

Thanks in advance!

Nevermind, I guess the only way to do it is to separate the function as a core class and then create a CLR wrapper and then an SSIS wrapper.
