How can I deploy an unmanaged DLL with a WPF click-once application?
clickonce, wpf
Solution
Rather than going through the whole "Add Resource" rigmarole - I just needed to "Add existing item" into the root folder of the project and then set "Content" and "Copy Always".
Problem
I have a WPF click-once application that makes use of an unmanaged dll. When debugging locally I have just copied the dll into the debug/bin folder. How can I include the dll in the project (VS2010) so it is deployed and accessible to the application? I have tried adding it as a Resource and setting "Content" and "Copy Always", and the file does seem to be present in the setup/deployment files, however the application is not able to see it. If it helps, this is an example of the code I use to access the methods in the unmanaged DLL. ``` [DllImport("ODBC_VER_DETECT.dll")] extern private static long GetCompanyFileVersion([MarshalAs(UnmanagedType.LPStr)] String sDataBase, [MarshalAs(UnmanagedType.LPStr)] StringBuilder sVersion); ```
