Syntax highlighting failing in v7.16, works in 7.15

[geysernrd]

Describe the bug

In v7.16, much of the expected syntax highlighting has gone "all white," and none of the error highlighting (red squiggles) is working for me:

If I rollback to v7.15, it all works again:

My projects are still in .NET 6.0. Is a newer version required?

Machine info

• Windows
• .NET 6.0
• Ionide version: 7.16 vs. 7.15

I believe you don't have the syntax highlighting and the error message Ionide is not started yet / project not loaded.

I am saying that because you can see that the Reference and inline hint are not their yet. Do you have intellisense in the file ?

Could you please share the output of the Ouput > Ionide to check if there is an error message in it?

[geysernrd]

Hi @MangelMaxime,

It may be that the project isn't fully loading, but if so it never does. I've waited as long as two hours (while doing other things, of course) and the syntax and error highlighting never appear in 7.6. In 7.5 every loads up in 5-10 seconds. Also the "project loading" indicator in VS Code only lasts a few seconds, if at all.

Apologies for my ignorance on this next part: I tried Output > Ionide in the terminal and got back "The term 'Output' is not recognized as the name of a cmdlet, function..." Is there somewhere else I should be entering that command?

Thanks!

By the way, IntelliSense does work. E.g., I can backspace to "ValidationHelpe" and it correctly suggests "ValidationHelpers" at the top of the snippet above. But then it's still white and inline-hint free after I accept it.

Is this the Ionide intellisense or the basic VSCode intellisense based on the file content ?

Ionide intellisense should have some symbol on the left of the tooltip and not just abc

Here is how you can find the output panel:

Ah, good call, it's just the VS Code IntellSense (abc).

Thanks, here is the Ionide output:

To echo, I have the same problem, that the extension is just "not there" contributing anything as of version 7.16. I've turned on all the logging I can find, and can't see the issue. The only difference I can even find in any logged thing is that in the successful case, in the Ionide output window,the below lines appears:

[13:15:36 DEBUG] [Main] Activating features

[leonitousconforti]

I have the same problem as well, there is no error I can find anywhere in any of the logs it just doesn't seem to load

[geysernrd]

Unfortunately I've just confirmed that the issue persists in v7.17, so at this point I'm still stuck on 7.15.2.

If I'm on 7.15.2 for a while, will there be any issues upgrading to .NET 8? (I'm planning to skip over 7 when v5 of the SAFE Stack is released.)

EDIT: Looks like I'm behind the times and SAFE V5 has released. I may just attempt the upgrade and see what happens.

[TheAngryByrd]

I think this issue is because something isn't working with only the 6 SDK installed. I use it at work with 6/7/8 installed and don't see this behavior.

[geysernrd]

Thanks, @TheAngryByrd. I will upgrade and attempt to confirm.

[philipcraig]

So we have the essential issue found. Ionide no longer works on .Net SDK 6., as of Ionide version v7.16. The release notes don't mention this.

Would anyone be willing to reinstate .Net SDK 6 support, or should there be a documentation update and a (late) release note mentioning the dropping of .Net SDK 6 support?

[baronfel]

Not supporting 6 is a bug, we'll take a look.

[geysernrd]

To confirm, after upgrade to .NET 8, Ionide is working again for me.
