The IJW mechanism is slightly faster for example, the IJW stubs do not need to check for the need to pin or copy data items because that is done explicitly by the developer.

It clearly illustrates performance issues. In this case, the fact that you are translating from a Unicode string to an ANSI string and that you have an attendant memory allocation and deallocation. If you call many unmanaged APIs using the same data, marshaling it once and passing the marshaled copy is much more efficient than re-marshaling every time.

Marshaling must be specified explicitly in code instead of by attributes which often have appropriate defaults. If the application uses mainly unmanaged data types or if it calls more unmanaged APIs than. To call an occasional unmanaged API in a mostly managed application, the choice is more subtle.

In user In general, we recommend that you use Unicode versions of unmanaged APIs because that eliminates the translation overhead from the native Unicode format of.

For example, suppose there is a function MakeSpecial in mylib. The difficulty here is that we cannot delete the memory for the unmanaged string returned by MakeSpecial. Other functions called through PInvoke return a pointer to an internal buffer that does not have to be deallocated by the user. In this case, using the IJW feature is the obvious choice.

You cannot return the same exact pointer from a native function that you took as a parameter. This topic also provides links to an introduction to instrumentation and tracing, trace switches, trace listeners, tracing code in an application, adding trace statements to application code, and compiling conditionally with Debug and Trace. Debugging Windows Service Applications Provides considerations for debugging Windows service applications, including setting up, attaching to the process, debugging the code in the service's OnStart method and the code in the Main method, setting breakpoints, and using the Services Control Manager to start, stop, pause, and continue your service.
