to use "object" - if you want a reference to absolutely anything, that's the type to use. Now, that's fine so long as you only ever want one delegate registered at a time - the static variable will prevent the delegate from being garbage collected. Are you okay with that limitation?
Object reference not set to an instance of an object. Possible solution It appears that garbage collection is being done on objects from the NativeInterop package before the necessary callback is successfully made. Garbage collection should not occur until the callback is made successfully. Additiona...
The code of it is identical to all the other delegates, why would this one trigger the MDA to say it has been garbage collected? Here is the code for how they are defined and used internal unsafe delegate void API_DLL_LinkStateCallbackRoutine(LinkStateStruct *data); internal delegate in...
When you use a delegate inside a call, the common language runtime protects the delegate from being garbage collected for the duration of that call. However, if the unmanaged function stores the delegate to use after the call completes, you must manually prevent garbage collection until the unma...
I'd like to mention also that on the second render of the component, the originaldispensefunction gets garbage collected (freeing up memory space) and then a new one is created. However withuseCallbackthe originaldispensefunction won't get garbage collected and a new one is created, so you...
Similar rules apply for Lua strings which are implicitly converted to"const char *": the string object itself must be referenced somewhere or it'll be garbage collected eventually. The pointer will then point to stale data, which may have already been overwritten. Note thatstring literalsare aut...

Process terminated. A callback was made on a garbage collected delegate of type 'GLFW.NET!GLFW.MouseCallback::Invoke'. at GLFW.Glfw.PollEvents() at GLFW.Glfw.PollEvents() at HelloTriangle.Program.Main(System.String[]) I've looked at "#19" and my code is very similar to your "solutio...
The onstop callback needs to be cleaned up because of the circular reference issue which might cause that piece of code to never get's garbage collected. One easy workaround is to not dispose the player in the next line from 'stop' but instead dispose the player. on the onstop callback...
