I use both Delphi and Visual Studio (C#), and I've noticed a difference in how code-completion works which I find really annoying. In Delphi, if you edit existing code so that you change the variable you're using, code completion will give hints based on the code before your cursor. For instance, inserting an "I" into myString to become myIString would give a code hint to show any available variables starting with "myI". Selecting one will then overwrite myString with the new one.
In Visual Studio doing the same thing brings up a code-completion menu with all available variables, and none selected so you see the top of the list. You have to completely delete the variable you're using and start again before you get meaningful code completion.
I seem to make changes like this quite often (maybe I should just get it right in the first place!) so it gets a bit annoying having to remove code, and can be trickier on longer lines with lots of parts to them.
Here's some screenshots which (hopefully) illustrate the difference. I was struggling how best to word this!
Code completion in Delphi
Code completion in Visual Studio
I've tried playing with the Intellisense settings in Visual Studio and there's nothing there which seems to change the behaviour. Is there any way of replicating it in C#?

For now, VS doesn't support for this behavior. The auto completion won't work when we insert a character into existing variable. It will take effect when we type a character in a empty place.
Type character in a new place, the intellisense works.
Insert character,the intellisense not works.
In my opinion your suggestions is really meaningful. I think it could be better if we have a new option to support for auto-completion when insert character, so I suggest you can Go=>Help=>Seed Feedback=>Provide a suggestion to post your idea there.
We who interested in it will vote for you if you share the link here.
As alternative ways:
You can go Tools=>Options=>Text Editor=>C#=>Intellisense=>Enable Show Completion list after a character is deleted option.
Then you can insert 'i', the statement could be myiSring1.GetType(); And delete any or all characters in the String1,it would show the intellisense like below:(e.g:I delete 'r'.) Apparently, this is what you really want, but as I mentioned above, VS itself doesn't support this behavior for now, hope you can use 'delete option' saves some time. Sorry for the inconvenience.
Also, you can check if ReSharper can meet your needs,since it's a third-party tool which seems to charge after xx-days trial, I have no further details for it.
Hope all above helps :)

New install of Visual Studio 2022 - NET 6 project.
In the past, the variables (in the pic below) would have little squiggles underneath them and when I hover the mouse over them a suggestion would pop up stating something similar to (names are not cased or capitalized correctly). It was like the IDE had a code analyzer (maybe an extension/addon) that constantly monitored coding styles.
After installing VS 2022 I cannot figure out how to make these types of suggestions appear. Can anyone help me with this?
Edit - Additional info
I think, maybe it's rule IDE1006 that I am trying to activate in the IDE
Also, in (Tools)(Options) I have these settings. But not a single notification about variable names that violate IDE1006
I can see all of these notifications too (pic below), so, I know with certainty the code is being analyzed (the analysis is just not pointing out (variable name) violations)
There is a setting for enabling and disabling specific style guidance selections.
You will need to navigate to Tools/Options/Text Editor/C#/Code Style/General
In addition to catching flat out syntax errors, Visual Studio does have code analyzers.
This feature still works. Looking at your image, it appears there are those dotted lines under offet_A and offetBecause. It's hard to know exactly why because I don't have enough context of the few lines we're looking at.
I do know that method names starting with lower-case letter generally trigger this warning, but again, we can't see if you have that going on either.
So my answer is this feature is still active. But it only happens for naming that violates accepted naming conventions.
I edited my .editorconfig file (added the lines below), and now the Style Rules, specifically (IDE1006 naming rule violation), etc are enabled/flagged in my source code
dotnet_naming_rule.locals_should_be_camel_case.severity = suggestion
dotnet_naming_rule.locals_should_be_camel_case.symbols = locals_and_parameters
dotnet_naming_rule.locals_should_be_camel_case.style = camel_case_style
dotnet_naming_symbols.locals_and_parameters.applicable_kinds = parameter, local
dotnet_naming_style.camel_case_style.capitalization = camel_case
Here is my problem. I have a C# class file loaded in Visual Studio that I am working on. I made a class and created some properties inside of said class. I collapsed the properties like so:
I collapse the properties with the little +/- button on the side of each. I want to collapse each of them since I have a lot of other classes with properties and I don't want to see a lot of repetitive code (get, set).
Closing them works fine but after I work on some other classes in the same file the properties re-open so I can see the code:
This happens relatively often and is quite annoying. I have a lot of lines in the file and I sometimes have to work with a small screen. Is this a glitch/bug or something else? (I am using Visual Studio 2010 C# Express)
Thanks for your help.
There is no way to solve this so far, but this does the trick. Press CTRL-M and then O and it will auto collapse everything in the current file you are on.
An alternate tip to #DJKRAZE's excellent answer is Resharper. I use Resharper and it takes care of this automatically for me. For example if I write this code:
The 4 line property procedure causes a Expand/Collapse that is causing you grief.
Resharper makes it one line. When I delete the last curly brace (namespace) and enter it again, the code is automatically formatted (Edit > Advanced > Format Document doesn't do this):
You can use this:
#region some_name
//your variables or code whatever
#endregion
And then you can collapse the particular code, and the good thing it does not open like the way it happens in your case.
See if that worked.
If anyone knows the name for these types of comments, if one exists, please modify my question.
I frequently see comment blocks such as this:
/**********************************************
* Some Important Text Here
**********************************************/
Sometimes they can look like this:
/**********************************************
********* Some Important Text Here *******
**********************************************/
I've also seen them prettier than that.
They seem useful for noting sections of code, and important messages, such as license blocks. But, I feel like there *must* be a "lazy" way of doing this in Visual Studio, or at least an addon, because typing them manually is a pain.
Thanks!
P.S. If this feature or a point-and-click way to do it doesn't exist, then I know what VS plugin I'm writing next.
create a code snippet for them
You could perhaps look at GhostDoc, it is great for writing neat, clean, consistent style commenting in your code. It uses XML markup, and can later be exported for documentation.
If you want fixed-text blocks, then add a Code Snippet for each one you need.
If you want auto-generated documentation blocks for absolutely any code element, then you might like to try my addin, AtomineerUtils. (Similar to GhostDoc, but with significantly more features, a much better documentation generation engine, better formatting control (e.g. word wrapping of comments and documentation comments) and support for many more programming languages and documentation block styles).
You could create a toolbar macro which inserts that text at your cursor position when you click on the toolbar icon.
I have a C# project and some code pages have few thousand lines of code. I really like the idea of nodes in the code editor. I use it a lot and create many regions. But every time I open the project, all the nodes are expanded and I have to minimize them manually. It gets really annoying.
I have not found any help about this on internet nor in the options of VS. There must be a setting somewhere.
In the Options dialog onder Text Editor --> C# --> Advanced, there is an option "Enter outlining mode when files open". This should be checked.
In the IDE, from the Tools menu click Options. Alter default Outlining using
TextEditor->C#->Formatting->Advanced
There is a checkbox here you can use to set defaults for Outlining. This is VC# 10 Express but similar in other versions.
If you try the suggested change, you may be disappointed. According to this C# PM, who's responding to a similar complaint:
It is a bit confusing, but the
behavior you're seeing is intended.
The feedback that we received with VS
2003 was that we should persist the
outlining state of source files after
they have been closed and then
reopened. The option in Tools |
Option now effectively means what the
default behavior should be for a file
that you have never opened before. It
has no effect on files that you have
opened previously, since those files
already have a persisted outlining
state.
I don't want be a smart ass here, but often if you have that huge code in one file, you have more than one logical unit and might be able to (ans should) split it. (Single Responsibility Principle).
For my share, I don't like the regions because they are hiding code and I prefer to see all of it.
In Visual Studio Professional 2010 whenever I type the following:
new {
It automatically changes to:
new object {
Is there a way to make it not do this? "Object" does not have the properties of the object I want to anonymously create.

I'm pretty sure it's a bug, so I went ahead and reported it. Was going to do it sooner or later anyway :)
Hope that's okay with you.
You can disable the IntelliSense completing when you type the bracket.
On the Tools menu select Options. Then, on the right hand side, expand Text Editor then C# then IntelliSense. Remove the { from the textbox under the Committed by typing the following characters:
You may also have to uncheck the Committed by pressing the space bar or get in the habit of writing new{ and relying on the auto formatting when you close the bracket (though I've never done any ASPX stuff so don't know how good the auto formatting is compared to a normal code file.)
I've just gotten in the habit of typing "new{}". Intellisense doesn't kick in then. And since I'm always reformatting the page anyways with crtl-k;crtl-d, it spaces it out correctly later on.
