Visual Studio 17.3 warnings don't make sense - visual-studio-2022

Visual Studio tries to give me directions on what mistakes I might be making.
Very nice, but with each update, more warnings appear I can't make heads or tails of.
Look at the warning below:
Each and every reference to some item (variable, function) gets a red underlining with these warnings. "Not null"? I hope so! "Ambiguity"? With what? Itself?
Options? (And no, better not disabling the warnings. I don't want to miss real mistakes)

Okay, I found some weird "conflicted copies" of the designer.cs files.
After deleting them, all warnings disappeared except the obvious ones like
Constructs like is not null don't change it.

Unusual behavior of Intellisense in VB.Net 2017 in IF statements

Note: it is quite possible that I am being an idiot about this issue. If so, I apologize in advance. I did some looking (here and on other sites) and didn't see an answer. Perhaps I didn't properly phrase my search terms. Again, my apologies.
This behavior I am seeing started with VS 2017 and did not happen in prior versions of VS.
What happens is when I am typing an IF statement in VB.Net 2017, Intellisense and auto-complete either does not happen or changes my input to something completely different, and very un-helpful. To get back to the functionality I would expect, I have to stop what I am typing and space over and type: )then and press Enter. Then, when I go back into the body of the IF statement to specify the test condition, Intellisense and auto-complete work as expected, and as they did in previous versions of VS.
Is anyone else having this issue? Is there something that I can do (switch setting, etc.) to get rid of this annoyance? I would have to imagine that there is a setting somewhere that would fix this that I am unaware of.
Thanks in advance,
Bob Kiser

Visual Studio 2013 Compilation Error - Code not detected properly

Having a very odd issue with Visual Studio 2013, curious if anyone else is seeing anything similar. I have VS 2013 Ultimate, it seems like once a day, while I'm working with a file, the compiler just suddenly freaks out and doesn't detect my code anymore in my web forms. Take a look at the screenshot below (I just chose a random spot in the middle of the web form), but out of nowhere, VS starts erroring, telling me that variables aren't declared, that method arguments need parenthesis on lines of code that aren't methods, all sorts of whacky stuff.
I assure you, I don't have any broken references, I didn't forget to close an if statement.. nothing like that. All I'm doing it writing some code, and randomly the whole page just starts to error like this. To resolve, all I can do is copy the code contents, delete the page, recreate the page, and paste the contents back into my "new" file... same exact code, only no errors. I wouldn't even worry about doing this if I wasn't doing this at least once a day.
Any help is appreciated, thanks!
Edit: For what it's worth, I found a slightly easier workaround for this issue. If I edit the properties of the class file to "Do not Compile" and then back to "Compile", the IDE is able to read the file just fine...
It looks like this is simply a bug in the Vb.Net Compiler / IDE. I agree it's unlikely to be a bug in your code because you can see that the error squiggles don't line up with places that would represent the errors you are reporting. This is sometimes a sign of an IDE bug
In terms of fixing the problem though you can probably get them to go away by closing and reopening the solution in question. Baring that restarting Visual Studio. I wouldn't resort to deleted / recreating the page.
Long term though you may want to file an issue on connect so the IDE team can try and fix the problem.

Only Shows Error List For One vb File

I'm kind of new to Visual Studio. I've built a few simple programs in it, but now I'm in the process of rewriting a huge system I wrote in VBA. What is frustrating me is the Error List in VS is only listing errors for one .vb File in my project, lets call that VBFile1. Now, when I work on another vb File, VBFile2, which is in the same project as VBFile1 no red squiggles or errors are listed for VBFile2. I don't understand how this could happen. This is what I've tried/checked:
Filter is set to 'Current Project' and I played around with the other Filter settings but no change.
Checked the Text Editor under Options and according to the research that I've already done it is fine. Plus, I have never changed any of these settings anyway.
Closed and re-opened Visual Studio.
Closed all open files in the Project and still displays the same error list
Close all files except the VBFile2 but still shows the same error list of VBFile1.
I have Visual Studio 2012 Ultimate. I feel like this should be an easy fix...I just am really confused what's going on.
Hope this makes sense!
UPDATE: Excluded from project, VBFile1 and finally errors are listed for VBFile2...why would this be?
I am not sure if it has been fixed in Visual Studio 2012, but there is a Connect Request for Visual Studio 2010 with a resolution of won't fix because of performance issues. The effect your are seeing is because you have exceeded the maximum number of errors for that project (what I am used to seeing is 102 as the threshold), it will not show you anymore till you fix the ones that it has already shown you.
According to this MSDN article, which I found through this SO question the limitation is still there for the IDE but has been removed for the command line compiler.
From above MSDN Link:
Limitless (Command-line) Errors!
This is actually a good thing, let me explain. For performance reasons, the Visual Basic IDE maxes out at 101 errors (with error #102 being “Maximum number of errors exceeded.”) This can make it difficult to estimate the amount of work remaining in certain situations, particularly in upgrade scenarios. We have removed this limit from the command-line compiler in this release, though it still there in the IDE. What this means is if you want to know exactly how many errors there are for a project, just invoke the compiler through msbuild.exe or vbc.exe and you’ll get your answer.

Why is my vs2012 forcing extra parentheses

First, thank you for taking pity on me and reading this issue. I CANNOT for the life of me figure out what extension I might have installed that is causing this issue, but it is EXTREMELY cumbersome.
Whenever I begin to type code (VB I think it also occurs in C#), for example "For Each" once I hit the F it forces a set of parentheses. Which would look like F(), but because I keep typing it looks like F(or). This only occurs when coding inside code blocks like a function or a sub, but when I'm creating the function it does not occur. I've disabled any and all power tools and the like, or at least I'm 90% sure I've done this for all of them, and yet it still occurs.
I'm usually pretty proficient at digging about the net and finding the answer, but for this one I'm at a loss. There is just too many keywords involved, so all I see is non-related topics, or how to make the parentheses occur, not get rid of them.
If anyone can provide some steps to resolve this, I'm happy and eager to try them. It's just such a hassle to live with for right now.
If you think it is a Visual Studio extension, then start by disabling all of them and adding them back one at a time.
You can also run VS with the command line switched to disable features.

The simple answer to the cause is the Codealike VS Extension. I logged a bug with them and hopefully they'll fix it soon

IntelliSense not working VS2008 VB.Net

I realize this question has been asked before, but I was not able to find anything that worked for me yet.
Things I have tried:
Switched settings back to default (mulitple ways)
Project Builds/Compiles fine
Closed VS and restarted
The only thing I haven't been able to try is deleting the ".ncb" file, but that's only because I can't find it. In fact not a single one of all our projects have such a file!
So the first question is why can't I find this file in the solution's root directory? The only file I have there besides the .sln is the .suo.
Then if that doesn't work what other options do I have short of un-installing and re-installing?
As for how it happened this might help. While using VS2008 and VSS6.0 (yuck) I made a number of changes to a lot of files via Find&Replace that I didn't mean to(had Entire Solution selected instead of current document). To undo the changes I exited without saving, reopened the solution, then Undid checkout. After that I lost intellisense! I can't imaging how they're related but it might help.
Thanks,
Jeff
IntelliSense usually stops working when it can't compile correctly. Try a new simple project from scratch and see if it works, if it does you have your answer.
Is this for C++ code? If it is, my suggestion is not to try fixing built-in IntelliSense at all, rather try some 3rd party replacement. My favourite is definitely Visual Assist X, which is lot more robust (it almost never stops working, and it is able to parse even very complicated templated and preprocessed stuff, which often makes IntelliSense "lost".
Visual Assist works with other languages including Visual Basic, however this is something I have no practical experience with. Still, there is a free trial - you may try it, I expect it will be superior to IntelliSense even for VB.
Answer:
I figured out how to fix it. Apparently while I was undoing those changes I somehow excluded the file that I wasn't getting intellisense in from the project.
I just right-clicked on it and said "Include in Project" and viola! Intellisense worked again.
Sorry for the false alarm but I appreciate the effort.
