should i need to place the these dll files explicitly in the system32 folder of operating system or will these be placed automatically at that location when i install the sap.net.connector 2.0.
and also plz tell me the difference between the development system and deployment system
A little more info:
1. librfc32.dll is also added when you install SAP Logon.
2. the connector dlls (sap.connector.dll and sap.connector.rfc.dll) <i>are</i> installed automatically by the connector installation. But since the installation is done only on the <b>development</b> machine (where you have Visual Studio) then on a deployment machine you need to put these files yourself.
These files would not be automatically be placed by .Net connector setup in system32 directory.
A development system is the one where an application is developed using SAP .Net connector (in this case) while a deployment system is where the application you develop would actually be used (on a customer's machine for example)
