Can't debug in Visual Studio Code

[AlexFolland]

This is mattering more, so I'm reporting it as an issue in case you have any suggestions. Here is the debug console output when I try to "Start Debugging" in Visual Studio Code.

I'll install Windows 7 in a VMware machine today and see if I can reproduce this.

[SWY1985]

If it's no problem for you, can you uninstall the .NET Core SDK and install this older version: https://github.com/dotnet/core/blob/master/release-notes/download-archives/1.1-preview2.1-download.md

This could be a temporary solution to the debugging problems.

[AlexFolland]

I will try it.

[AlexFolland]

Actually, that is the version I already have installed. It was the latest version on their site as of 2017-03-01 when I installed it. Where is a more recent version?

[AlexFolland]

I'm trying this one now: https://github.com/dotnet/core/blob/master/release-notes/download-archives/1.1.1-download.md

[AlexFolland]

Same thing, but with the higher version number:

[AlexFolland]

Why is it compiling a dll instead of an exe? How did you build an exe release before? The debugger not attaching may be because the equivalent of "Just My Code" is enabled. Perhaps that can be disabled, allowing debugging of dll files. This is an uneducated guess though. Googling this did not give me any useful results.

[SWY1985]

The reason .NET Core compiles to .dll instead of .exe is that by default it requires the .NET Core runtime to run. It's possible to publish the game in a way that it runs stand-alone.

To publish/compile to .exe, you need to remove the following line from the project.json: "type": "platform",

Then, open a command prompt to the CivOne root folder and type: dotnet publish -c release -r win7-x64

It will create an .exe file under ~/bin/release/netcoreapp1.1/win7-x64/publish

This whole process will become a lot easier soon... but .NET Core is still in development and things change all the time. I'm going to migrate the project from project.json to .csproj soon, and I'm going to provide scripts/batch files that help with the compilation/publishing process.

[SWY1985]

It's strange, I had a fresh Windows 7 install and everything worked the first time, including debugging.

[AlexFolland]

I installed that version. I built the exe. That worked well. It's just debugging that doesn't work, still with the same strange messages. What is the debug output that you get near the start of your debugging sessions? Do you see any of the same messages I've pasted?

[SWY1985]

I've upgraded the project to work with the latest .NET Core version (1.1.1) and to use .csproj instead of project.json. Please update to the latest code.

I assume that doesn't fix debugging. There's one thing I can think off that might work. Can you press Ctrl+Shift+P and run the following command:

After pressing enter you might get an error message from VScode that the action failed, but after a while the bottom console will show a message that it has worked. After that debugging might work.

[AlexFolland]

I can press enter there, with what I see in your screenshot showing, but it doesn't seem to do anything. There's no feedback whatsoever anywhere that I can find on my own. I waited several minutes. Then, I tried debugging and the result was identical.

[wenisman]

having the same issue. no dotnet debugging, is there a work around or resolution yet?

[SWY1985]

I have tried on about 5 machines, running Windows, Linux and macOS and I haven't had any problems with debugging. Unless I can reproduce this, it's going to be very difficult to figure out what's happening. If anyone else has an idea, please let me know...

For now, you could try opening the project in Visual Studio Community Edition and see if debugging works from there...

[SWY1985]

Out of nowhere, I have the same problem now.

[SWY1985]

It seems to be caused by OpenTK, which is only unofficially working on .NET Core. I'm considering getting rid of OpenTK (sooner, rather than later) in favour of my own SDL implementation, which is going to take a while to develop. I'll see what I can come up with today.

[SWY1985]

I've tested it on my Linux machines and they all work find. It appears to be a Windows-only problem... and probably not every Windows installation either.

[wenisman]

Seems to have resolved with a fresh install of vs code, but it was happening on my Mac so not a Windows only big I'm afraid

[SWY1985]

Unfortunately, that (reinstallation) solved some but not all of the problems I have with VS code. I can't debug the OpenTK version on one of my (Windows) computers now. My other Windows machine has no issues, and on Linux everything also works fine.

The debugger crashes when creating an OpenTK window.

I'll try to find a solution to this...

[SWY1985]

The SDL runtime is now default. #419 Could you please check if debugging works now?

[SWY1985]

Can anyone confirm that this is still an issue? I've been running CivOne on many Windows, Linux an Mac installations and I have not encountered this problem anymore.
