I get reasonable call stacks for all the other threads, including the other worker threads, but it looks like the ones that appear to be hanging I get no useful information once it gets into the bad state. Before it goes wonky, I get good call stacks on all threads. I am running Debug, and can step into the DLLs, so the build is OK.

I don't know where to go from here.... Something in dotNet must have changed that affects this, as I haven't had this problem with v428 since we got the last deadlock issue sorted out.

I found a bug in my code (a hard-coded path pointing to the no-longer-there v428 directory), and have gotten past that. It now comes up, indicates the board is connected, but when I try to come out of E-Stop, it comes partially to life, but the worker thread that updates most of the GUI controls seems not to be running.

I get reasonable call stacks for all the other threads, including the other worker threads, but it looks like the ones that appear to be hanging I get no useful information once it gets into the bad state. Before it goes wonky, I get good call stacks on all threads. I am running Debug, and can step into the DLLs, so the build is OK.

I don't know where to go from here.... Something in dotNet must have changed that affects this, as I haven't had this problem with v428 since we got the last deadlock issue sorted out.

I found a bug in my code (a hard-coded path pointing to the no-longer-there v428 directory), and have gotten past that. It now comes up, indicates the board is connected, but when I try to come out of E-Stop, it comes partially to life, but the worker thread that updates most of the GUI controls seems not to be running. Looking into that now...

I get reasonable call stacks for all the other threads, including the other worker threads, but it looks like the ones that appear to be hanging I get no useful information once it gets into the bad state. Before it goes wonky, I get good call stacks on all threads. I am running Debug, and can step into the DLLs, so the build is OK.

I don't know where to go from here.... Something in dotNet must have changed that affects this, as I haven't had this problem with v428 since we got the last deadlock issue sorted out.

I found a bug in my code (a hard-coded path pointing to the no-longer-there v428 directory), and have gotten past that. It now comes up, indicates the board is connected, but when I try to come out of E-Stop, it comes partially to life, but the worker thread that updates most of the GUI controls seems not to be running. Looking into that now...
