Any plan of improving Visual Studio Extension?

try erase all to see if that help.

The problem is the Visual Studio Extension. It’s VERY buggy.

I am in the process of developing a program for a Flea. It drives a stepper motor for a watch winder. I have been happily compiling, loading and debugging without any issues.

There is something in your solution/project that is messed up…

First, have you tried building a new solution and adding your files to this solution? This has been known to help in the past.

If it is possible, you can send me your solution directory and I will take a look and see if I can get around the problem. No promises…

Dat_Tran · May 8, 2023, 12:12pm

Did you add any reference? If so, check every reference to see if there is yellow exclamation mark.

Dat_Tran · May 8, 2023, 12:22pm

Or if you can share the project to us to reproduce the issue.

dcyonce · May 8, 2023, 2:42pm

Doesn’t seem to matter what application.

But, I figured out one of the issues. When I have a solution with multiple projects, the VS Extension can get confused. When I set the active application, the VS Extension keeps trying to deploy the previously selected application.

Looks like this has been a problem for many years.

Once the TinyVLR Visual Studio Extension thinks the assemblies are updated, it’s very hard to get it to deploy the correct set of assemblies.

If I had the source … I would find these FRUSTRATING bugs !

dcyonce · May 8, 2023, 2:52pm

Dat Tran,
Here are a couple more issues I have found:

TinyCLR support for “foreach of a string”
With the following code anywhere in an application, Visual Studio gives an error message : CS7038 Failed to emit module ‘XXXXX.XXXX.XXXXX’: Unable to determine specific cause of the failure.
Took me a long time to find this one since Visual Studio doesn’t tell you where the problem is or give any hint…

string s = "some string";
foreach (char c in s)
{
	Function( c );
}

TinyCLR will cause Visual Studio to crash
Anytime an application being debugged runs out of heap, TinyCLR debugger locks up and Visual Studio crashes. Upon reload, Visual Studio recommends disabling TinyCLR Extension to prevent crashes.

This one is fairly easy to reproduce. Create a recursive loop, allocate too much memory, etc.

Haven’t been able to pinpoint the other issues. I’ll post them if I can get them cornered.

As you can see, the TinyCLR Visual Studio Extension ONLY wrote the first 6 sectors of the application! Where is the rest !!! … the VS Extension skipped them entirely.

The next time I attempt to deploy, it writes another 12 sectors. But, still not the entire application.

Known issue. Been around a long time. Would be interesting to know why this is hard to fix.

I only see this issue once a project.

Mike · May 8, 2023, 6:00pm

Another known problem.

dcyonce · May 8, 2023, 7:19pm

Hmm … is there a list of “known problems” or should I start one

Mike · May 8, 2023, 9:42pm

Dat_Tran · May 9, 2023, 1:47pm

This doesn’t mean the extension deployed incorrectly. if you already deployed 1MB, then on the second deploy, if you changed only few bytes somewhere in first 2KB in the source code, meaning only first 2KB need to be rewrite, so you will see only first sector 2K shown. That will help reducing time when you deploy large projects.

You can check by erase deployment and redeploy again, you should see all data will be deployed.

Every time you deploy your project, the sector you see may different, depends on how much you changed in your source code. And if you don’t change anything from the last deploy, no sector shown from the output window, this is done by purpose, not a bug.

Back to your issue, it could be a bug in extension, or something with your project setup.

So we need to know how to reproduce the bug first. If you can share your project to us, we will take a look quickly.

Or if your project is private or sensitive that can’t be shared, just make a simple project, reproduce your issue on that project and send to us.

Dat_Tran · May 9, 2023, 2:01pm

Also, the sectors may shown:

sector 1
sector 7
sector 8
sector 10
…

they are also not a bug, because depends on where you changed in your source code. It doesn’t need to be 1,2,3,4,5,6,7…

dcyonce · May 9, 2023, 3:19pm

Dat Tran,
Thanks for your help. Let me clarify…

The logs in the previous post are consecutive. NO changes to my code at all.
All consecutive deployments within a few seconds.

Here’s what I did :

Erased the application using TinyCLR Config
Attempted to deploy an application (119,484 bytes)
TinyCLR only deployed part of the application (sectors 1-6)
Immediately attempted to deploy again.
TinyCLR only deployed another 11 sectors this time.
Still not the entire application.
Each time, the debugger complains “Cannot find any entrypoint!”
Attempted to deploy the same application again.
Unfortunately, TinyCLR VS Extension is now confused and will not deploy anything.
Switched to an empty application with only a few lines of code.
Attempts to deploy all fail. TinyCLR VS Extension is now hopelessly confused and always thinks everything is just fine and the entire application is deployed (no matter what application I attempt to deploy).
Gave up. Went to bed. I’ll try again tomorrow.

Next morning … rebooted computer in order to reset TinyCLR USB driver and VS Extension.

1st attempt to deploy original application … deployed part of the application (sectors 9-52), but TinyCLR hung at “Waiting for device to initialize”. Waited about a minute.
Pressing RESET on the Pico … VS Extension still hung.
Unplug Pico and plug it back in … VS Extension still hung.
Hit STOP within Visual Studio. 5 to 10 seconds later. VS Extension is stopped and Visual Studio back to normal.
The VS Extension hanging at this point sort of makes sense. It hasn’t deployed the entire application. It’s going to fail at some point.

Here’s the deployment log:
It deployed another part of the application (but not all), sectors 9-52, but hung up at “Waiting for device to initialize”.

Everything works just fine. I can now deploy and debug any application to any board … for a while that is. In about 20-25 minutes the VS Extension get confused and starts giving random errors and will not function once again.

A few clues …

At first I thought I must have a bad USB port or some other device on the USB bus is interfering. Nope, the problems are not isolated to a single computer.
Seeing that other people on the GHI Forum had the same set of issues helped focus my efforts on isolating the problems.
The problem seems to be focused on TinyCLR Visual Studio Extension and/or the USB Driver.
Once it is confused, a PC reboot helps … but not always. Sometimes it works great for a few deployments after a reboot … sometimes it works great for an hour or more.
If I take the “partially deployed” Pico to another computer and attempt to deploy the EXACT SAME application the same way, it will succeed (until that copy of TinyCLR VS Extension gets confused and gives up).
It does not matter what project I attempt to deploy and debug. The VS Extension will eventually stop working. BUT, smaller projects have a much greater chance of deploying over and over successfully.
Large projects (any large project, it does not matter) will much more quickly cause the VS Extension to become confused.
The faster the PC, the quicker is gets confused and gives up.
I have a much, much slower machine at another location. The TinyCLR VS Extension works for hours before getting confused and requiring a reboot.
When using my main desktop machine (blindingly fast PC), the VS Extension works for 5 to 20 minutes before it deteriorates to the point that it no longer works.
Sometimes the TinyCLR VS Extension fails quickly, sometimes it starts giving odd errors and slowly deteriorates to eventually stop working.

My educated guess : the TinyCLR VS Extension and/or USB driver does not recover well from ANY USB hiccup or error. At that point, it’s internal state is corrupt and possibly unrecoverable.

Hope this information helps you to locate the problems. If I can assist further, just let me know.

We are working hard to get this application to the point that we can create a few test boards. We are already behind schedule. At this point, we should be running the 2000 unit trial that our customer has ALREADY committed to. Phase I rollout of 75,000 units is slated for this summer … I don’t think we will make that deadline.

I am available today and tomorrow (May 9 &10), but am leaving for Europe on Wednesday evening for about 5-6 weeks with limited email and Internet access during this time.

Once again … thanks for your assistance !

On different computer it work just fine?

On ANY computer TinyCLR VS Extension works just fine … for a short while.

It would be interesting to see what would happen if you ran the TinyClr development environment in a virtual machine. It would provide an extra layer of USB handling.

I used to run GHI stuff in virtual machines on an Intel Mac. I have not tried it recently.

Hmm …
Interesting idea. I’ll have to try it.

I wonder if GHI has a virtual device I could try ??

I run my TinyCLR development in a VMWare virtual machine using Wmware Workstation Pro. So far I have had no issues. I am running on Win10 for the main OS and the VM is also Win10. I have no idea if it would work on a MAC.
I create a VM for each major project I am working on. In my opinion, it makes it easier to keep things straight, especially if there are different TinyCLR firmware versions for different projects.
