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.

I have a problem with several references in my VB.NET project.
For example I have this line of code:
Dim m As New Chilkat.Email
It comes from the library "ChilkatDotNet45.dll".
When I click on "References" and locate this dll, I can see that it has the settings "Use local copy" and "Do not include interop types".
When I switch to Release mode, the compiler tells me that "Chilkat.EMail" is not defined.
I have this problem with several DLLs, so it is not specific to Chilkat.
Can somebody tell me what I did wrong?
Thank you.
One of the standard approaches to solving any programming-related issue is trying to reduce the scope of the investigation. If you have a big project, in which something doesn't work, try to create a smaller project, and try to replicate desired functionality in it. Reduce as much as possible, down to a brand new project with maybe 5-10 lines of code in it.
If you were unable to solve your problem after making a reduced test case, now it's good time to post it on StackOverflow. I am usually reducing problems while writing a question on SO (not before, as one might think), constantly thinking "ok, is it minimized enough"; and this is how 90% of the questions never get posted - I often find a solution along the way of reducing my question to bare bones. :)
In your case, can you build a simplified project which has this problem and post a link here? We could then try switching Debug to Release on our machines and see if the we can reproduce. There are too many options to do the guesswork.
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.

I have a fairly simple one solution project in VS2012. Standard windows forms, no special DLLs.
I get to a point were if I add more code to any form, or add a new control, the build fails in DEBUG mode. If I remove the line or the control, it works.
If I switch to RELEASE, the build succeeds.
If I create a new configuration and copy RELEASE, then that too fails.
If I revert to VS2008, all is fine. If I then re-convert the solution, it will be fine for a while.
Anybody else see that? I have researched the cases about missing DLLs and locked files, but that doesn't seem to apply. Neither does renaming the assembly work.
After many hours of looking at the options, a workaround is to turn on optimisations in "Advanced Compile Options".
I do not know what optimisations actually optimise, but they are turned off in debug by default because the debugger doesn't like them. Apparently, they will move code around.
This is obviously only a workaround and not the cause, so any other suggestions are welcome!
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
I'm seeing a strange build bug a lot. Sometimes after typing some code we receive the following build error.
Class 'clsX' must implement 'Event PropertyChanged(sender As Object, e As PropertyChangedEventArgs)' for interface System.ComponentModel.INotifyPropertyChanged'.
And
'PropertyChanged' cannot implement 'PropertyChanged' because there is no matching event on interface 'System.ComponentModel.INotifyPropertyChanged'.
Those error should never go together! Usually we can just ignore the exception and build the solution but often enough this bug stops our build. (this happens a lot using Edit and Continue which is annoying)
We're using Vb.net and c# mixed in one big solution.
Removing the PropertyChanged event and retyping the same code! sometimes fixes this.
Question:
Has anyone else seen this problem and has some suggestions how to prevent his?
We're using a code generator that causes this error to surface but just editing some files manually triggers this exception too. This error occur's on multiple machines using various setups.
Someone had the same exact issue discussed here. It sounds like there is an issue with this build picking up an old version of a binary. I would try the following in order:
Verify all assembly references use project references where possible within the Visual Studio solution.
Disable build parallelization in case there is some weird file locking issue with concurrent project builds. Go to Tools -> Options, Projects and Solutions -> Build and Run, then set "maximum number of parrellel project builds" to 1. Not the best solution but it may help narrow down the problem.
Disable the Hosting Process in case it's locking some file causing an assembly to not get rebuilt correctly. For C# project go to Project Properties, Debug tab, and uncheck "Enable the Visual Studio hosting process". For VB.NET project you'll need to Unload Project, Edit the project file, and add <UseVSHostingProcess>false</UseVSHostingProcess> to the PropertyGroup of each configuration. Again, not the best solution but you probably won't notice a difference.
Lastly, try doing a Clean + Build to try and resolve the issue when it occurs (I know this is not a fix but it's easy enough to do), also Rebuild may be slightly different than Clean + Build so try the latter if the former doesn't work.
As I can not comment due to lack of appropriate points.
But I would like to share one of my experience:
In an aspx.cs page I was working, used to compile fine and some time gave mysterious error of a variable not defined or function not defined or sometime variable or the function defined two times. I changed possibly each and every variable and function name but there seemed no effect , but after entering a simple space or a new line at any place in the file used to solve the compile error. At one time I tried to save the file (in a different encoding as i am used to experiments) and found that the file was not saving in the correct encoding (i.e. the ansi encoding because the file had a unicode character ), I removed the unicode character and that compile error didn't bothered me again.
This unicode character problem could be (not a hard and fast rule) there so you could check it.
Nuke & restore using source control (TFS instructions here):
Make sure you have everything checked in
Exit Visual Studio
Rename the project directory to .Bak (effectively deleting it)
Reopen Visual Studio and in source control:
Get Specific Version
check 'Overwrite... not checked out' and 'Overwrite ... even if local version matches'
Re-open project
Another problem: Make sure some source files are not newer than the current date (or your date is set back). Often this happens in apps where you are doing logic that requires certain things to happen differently on certain dates. You change your clock to test it, make a revision to the source with the date advanced, set the date back, and viola, rebuild does not rebuild that file.
You say 'typing it in again' - can you try just saving? After 40 years since MULTIX the .net build still decides what has changed by checking the file timestamp.
good luck!
When you get the error, is it always on the VB calling C# side, or vice-versa, or does it work both ways?
If the answer is either of the first two situations, try building the "callee" project within the solution before building the "caller" project to see if it stops the situation.
Also, just in case it may jog something for you to think about, does this error crop up when you change a VB file or a C# file, or is there no correllation?
Oh, and sorry this looks like an answer instead of a comment, I cannot post comments yet (need 50 rep).
