visual studio 2010 how to debug some code attached to a service

Question

i'm trying to debug some code attached to a service. this service has 2 .cs files implemented. The main program calls a function for a remote object which has been initialized by the service: string strCheminFile = DataLink.RemoteObject.CopyCaracMelToExcel(...);

the function is defined in the second .cs file of the service:

public string CopyCaracMelToExcel(...)
{
    CopyAlgomixToExcel copyCM = new CopyAlgomixToExcel(); 
    return copyCM.CopyCaracMelToExcel(...);
}

the function CopyCaracMelToExcel is implemented in another class library program

CopyCaracMelToExcel(...)

'implementation of the function'

this function is also declared into an interface file:

string CopyCaracMelToExcel(...;

when i try to debug the following step into main program: string strCheminFile = DataLink.RemoteObject.CopyCaracMelToExcel(...); i can enter interface file CopyCaracMelToExcel code but not the code in the class library program where the function is implemented.

i tried to attach the service as process into the debug menu. it doesn't work. also try to start the service as external application (into debug menu).

note: the service has two .cs file. only the main .cs has PDB file generated. the name of the second .cs file where the function is implemented doesn't have a pdb file and when i try to create a new breakpoint into this .cs file : the warning is : the breakpoint will not be hit. no symbols have been loaded for this document

thanks a lot

Answer 1

Try using the Debugger Launch method

System.Diagnostics.Debugger.Launch();

Edit:

Have you tried these?

debugging windows service gives No symbols have been loaded message

VS 2010 doesn't load PDB
