Auto format C# code In Visual Studio Code - c#

I have enabled the latest C# extension in my Visual Studio Code editor. Instead of formatting the code while saving or by applying the key combination Ctrl + K, Ctrl + F or Alt + Shift + F, I need to format the current line of code while hitting the Enter key. This feature is already available in Visual Studio, but not found in Visual Studio Code by default.
This is the sample code output I need to achieve:

I have found an option which makes it easier to format code while typing.
I applied the below settings in workspace settings:
{
"editor.formatOnSave": true,
"editor.formatOnType": true
}
This works fine for me.

Go to menu File → Preference → Settings.
Search for format
Select the options you would like:
Format on Paste
Format on Save
Format on Type
Close the Settings window.
You can also see it in your settings.json file:

Go to menu File → Preferences → Keyboard Shortcut (Ctrl + K, Ctrl + S)
Click on the keybindings.json link:
Enter the below binding for the Enter key. This binding will overwrite the defaults for current user.
{
"key": "enter",
"command": "editor.action.formatDocument",
"when": "editorHasSelection"
}
Another alternative solution is to use macros extension - a custom macros support for Visual Studio Code, so you will be able to do more than one command in one key binding.
Add macros to User Settings:
"macros": {
"formatWithEnter": [
"editor.action.insertLineAfter",
"editor.action.formatDocument"
]
}
And the below key binding to keybindings.json:
{
"key": "enter",
"command": "macros.formatWithEnter"
}

Code formatters available on Visual Studio default as
On Windows: Shift + Alt + F
On Mac: Shift + Option + F
If you again wish to do it when pressing Enter you need to set up your workspace preferences and then configure the key bindings:
{ "key": "enter", "command": "editor.action.format" }
It now formats the whole document if nothing is selected, and else it formats the selection.
Also there is the beautify.onSave, editor.formatOnSave option. Please try that too to make the code pretty.

Edit: This doesn't actually work because this will suppress the regular Enter key behavior
To get this to work for me I had to install two extensions
C# (powered by OmniSharp)
C# FixFormat
Without the second extension I was getting the error visual studio code there is no formatter for 'csharp'-files installed
I also made sure my Visual Studio Code was up to date (menu* → Help → Restart and Update or Check for Updates)
Then I added a custom key binding. menu File → Preferences → Keyboard Shortcuts → "For advanced customizations open and edit keybindings.json":
[{
"key": "enter",
"command": "editor.action.formatDocument",
"when": "editorTextFocus"
}
]
I had to type in the word enter because the dialog to capture keys doesn't acknowledge it.

Visual Studio 2019 IntelliSense changed (how to get prior behavior?)

Since I switched to VS 2019 (from 2017) I am pretty sure I got a degraded IntelliSense experience. I looked for settings under Tools -> Options... but did not find anything helpful.
The matter is this: suppose I have a variable kvp that has a property Key, I could type "key.", scroll to the "Key" property (if this is not already selected) and then type ";" to complete the statement.
But this does not work anymore. Instead it now ignores what I selected and I get
key.;
The only way to get the selected property is to explicitly hit enter. Same when I type the first character(s) to select the desired option: when pressing ; it just leaves what I already typed and adds the ; immediately behind it, ignoring what I selected in the popup menu.
What happened and how do I get the proper behavior back?
I am using the Preview version but I already had a couple of updates and it does not improve so I guess it is by design or default behavior now.
Here's some of my code for Perry. It is just an example though, the problem (or what I regard to be a problem) occurs with any object variable.
private static void AddBlockNodes(TreeNode node, IDictionary<string, Block> blocks)
{
foreach (KeyValuePair<string, Block> kvp in blocks)
{
string name = kvp.Key;
Block block = kvp.Value;
TreeNode childNode = new TreeNode(name);
childNode.Tag = block;
node.Nodes.Add(childNode);
AddBlockNodes(childNode, block.Subblocks);
}
}
it just leaves what I already typed and adds the ; immediately behind
it, ignoring what I selected in the popup menu.What happened and how
do I get the proper behavior back?
It is quite an abnormal behavior and l have installed Visual Studio 16.6.0 Preview 2.1 and test your code in my side and it works well.
Type variable kvp. and then select property Key and it types as expected. I did not face missing property Key during the process.
You can try these steps to troubleshoot your issue:
Suggestion
1) reset all settings by Tools-->Import and Export Settings-->Reset all settings
2) close VS Instance, enter the project path and delete .vs hidden folder which stores some Intellisense settings, bin, obj folder and then restart your project again. I wonder if you migrate an old project into VS2019 preview version, I think you should complete this step.
3) disable any third party extensions if you have under Extensions-->Manage Extensions in case they cause this behavior.
4) delete all component caches under C:\Users\xxx\AppData\Local\Microsoft\VisualStudio\16.0_xxx(16.0 is VS2019)\ComponentModelCache
5) try to create a new project in VS2019 Preview version and test whether this issue persists in the new platform and if it works, I think it is an issue of your project itself. Or you can try to migrate your project into the new project.
Hope it could help you.

Put class open brace on new line as you type in Visual Studio Code [C#]

In Visual Studio Code (MacOS) I've already spend hours finding how to put open brace to the new line when you type. I type this:
class Foo{
...and press Enter. I get the closing brace automatically:
class Foo{
}
But I want this (like VS 2017 did):
class Foo
{
}
I can do that with format command (Shift + Alt + F), but can I have it automatically?
I've tried different extensions (my lines from in User Settings).
ryannaddy.vscode-format: "format.newLine": { "brace": true }
Leopotam.csharpfixformat: "csharpfixformat.style.braces.onSameLine": false
"editor.formatOnType": true
Omnisharp: { "FormattingOptions": { "NewLinesForBracesIn...": true, } }
All without any success, none of these setting did this formatting on typing.
There should be an option in the VS Text Editor settings under
Tools -> Options -> Text Editor -> C# -> Formatting
Try to check them and see if that works.

Application not adding to startup + startup name is always "visual"

I tried adding my application to startup, if the user chooses that option. I made this code based on multiple answers on stackoverflow:
using Microsoft.Win32;
namespace Clientding
{
class Program
{
static void Main()
{
RegistryKey rkApp = Registry.CurrentUser.OpenSubKey("SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Run", true);
if (rkApp.GetValue("ItsAnApp") == null)
{
MessageBox.Show("This msgbox is to confirm that the code is being run!");
rkApp.SetValue("ItsAnApp", Application.ExecutablePath.ToString());
}
}
}
}
This does add the application to my startup list, but only with the name "Visual" which should somewhere be caused by visual express.
Also, the application doesn't actually show up on startup.
INFO:
I am running windows 8.
When adding to startup, I believe I hear the sound of a connecting device, then after 2 seconds, the disconnecting sound. I am 99% sure that this has to do with the startup program.
Any ideas why this code doesn't work?
Check the restriction that denies users to run application on the Windows start:
To restrict users from running specific Windows programs by editing the registry, follow these steps:
Click Start, and then click Run.
In the Open box, type regedit, and then click OK.
Create a DWORD value named DisallowRun. To do so:
Locate and then click the following registry key:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion
\Policies\Explorer
On the Edit menu, point to New, and then click DWORD Value.
Type disallowrun, and then press ENTER.
Double-click the DisallowRun value that you created in the previous
step.
Type 1 in the Value data box, and then click OK.
Create a new
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion
\Policies\Explorer\DisallowRun subkey. To do so:
Right-click the following registry key, point to New, and then click
Key: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion
\Policies\Explorer Type disallowrun, and then press ENTER.
For each program that you want to prevent users from running, create
a new string value in the DisallowRun subkey that you created in step
Use consecutive numbers to name the string values (starting with 1), and use the executable file name for the program as the data for
the string value.
For example, if you want to restrict users from running Microsoft Internet Explorer:
Right-click the following registry key, point to New, and then click String Value:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion \Policies\Explorer\DisallowRun
Type 1, and then press ENTER.
Double-click the 1 value that you created in the previous step.
Type iexplore.exe in the Value data box, and then click OK.
Quit Registry Editor, and then restart the computer.

Installer Class For Validate Serial Number MS Visual Studio 2010

I create a setup project in visual studio and want to add custom action to validate serial number. How can I do it?
EDIT 1:
I add Customer Information dialog in user interface of my setup project, and set ShowSerialNumber property to True. and want to validate entered user serial number , when user click next button on this dialog.
In VS solution explorer
Right click yoursetup >> View >> USerInterface
Right Click Start >> Add Dialog >> Select TextBox
Now made a Custom Class And add Install class file
In Install.cs
public override void Install(IDictionary stateSaver)
{
base.Install(stateSaver);
}
Not sure exactly what you want, or what you have tried, still ...
Make a boolean function:
private static bool isValidSerialNumber( string number )
{
}
The way you validate it depends on the type of serial number scheme used,
This might involve performing an RSA decryption on the serial number, or it might be as simple as querying a database or list to see if the serial number is there.
take a look at this question: How are serial numbers generated?

How to get the (.lnk) shortcut filepath in a program which started by the shortcut?

I have a c# program which open *.postfix file.
If a user runs a (.lnk)shortcut which points to my type of file, my program will open the target.
So, how could my program know it is started by a (.lnk)shortcut (and get it's file path)?
In some circumstances,i need to replace the .lnk file.
Thanks!
Edited
First, thanks to guys who answered my question.
By following #Anders answer, i find out my problem lays here.
I made some changes to windows registry, so browser knows to throw customized protocol string to certain program.
some thing like this..
[InternetShortcut]
URL=myProtocol://abcdefg.....
That's maybe why i lost lpTitle. :(
I'm going to try this way:
Whenever my program invoked, of course fed with %1, program checks current opened explorer(Window), and try to get it's current path with IWebBrowserApp. With that path and desktop of course, scan and analyze *.lnk to determine which one to replace.
I think this will probably work, but not be sure. I will try.
continued
In native code you can call GetStartupInfo, if the STARTF_TITLEISLINKNAME bit is set in STARTUPINFO.dwFlags then the path to the .lnk is in STARTUPINFO.lpTitle. I don't know if there is a .NET way to get this info, you probably have to P/Invoke...
You don't. There's no way to do it. End of story.
So this has been brought to my attention due to a recent downvote. There's an accepted answer showing an idea that gets the path to the launching shortcut most of the time. However my answer is to the whole. OP wants the link to the shortcut so he can change it. That is what can't be done most of the time.
Most likely case is the shortcut file exists in the start menu but is unwritable. However other cases involve the shortcut coming from another launching application that didn't even read it from a disk but from a database (I've seen a lot of corporate level restricted application launch tools). I also have a program that launches programs from shortcuts not via IShellLink but by parsing the .lnk file (because it must not start COM for reasons) and launching the program contained. It doesn't pass STARTF_TITLEISLINKNAME because it's passing an actual title.
If you're using Visual Studio Setup Project to build an installer and do the file type association, you should follow these instructions http://www.dreamincode.net/forums/topic/58005-file-associations-in-visual-studio/
Open up your solution in Visual studio.
Add a Setup Project to your solution by file , add project,New project, Setup & Deployment projects,Setup project
Right-click on your setup project in the "Solution Explorer" window,Select view,then select file types.
you'll see the "file types" window displayed in Visual studio.At the top of the window will be "File types on target machine"
Right-click on "File types on target machine".the menu will pop up with Add "file type" Click on this.
you'll see "New document Type#1" added,and "&open"underneath it.
The "new document type#1" can be anything you want - change it to something descriptive.although the user never sees this,never use something common- be as unique as possible,Because you can overlay current file associations without even realizing it.For example,you might think"pngfile" might be a useful name- but using that will now send all"*.png" files to your application,instead of to an image viewer.A good practice maybe "YourCompantName.Filetype",where your company name is your name of your company's name, and "Filetype" is a descriptive text of your file.
In the "properties" window for your new type,you will need to change a few properties.:
Command:Change to the application that you want to run.If you click on the "..." and you will proberly want to locate and use the "primary Output..." File
Description: This is the description of the file type(if it doesn't describe it's self"
Extensions:This your list of extensions for you chosen Program.Separate each one with a ","
Icon:This will associate the icon with your file type,This shows up in the window explorer.
Now we move to that "&open ".This is an action that is available if your right-click on the file.The default action("&Open" is currently set as the default) is what happens when you double click on the file.Right click on your "New document type#1" to add actions,but for the moment,lets define our "&open" action
Click on "&Open".You will see in the properties window "Name","Arguments","Verbs". Verb is hidden from the user,but is the key that is stored in the registry.Leave it same as the name,But without the "&".The default for"Arguments" is "%1",Which means to pass the full path and filename to your application.You can add other stuff here as well,if you need to pass flags to your application to do special stuff.All this infomaton is getting passed to your application on the command line,so you'll need to be familiar with the "Environment.CommandLine" object.
If you need to set a different action as your default,just right click on the action and "set as default"
Basically, you'll pass the file path as an argument to your program. Then if it's a console application or Windows Forms , you should check the arguments in Program.Main
static void Main(string[] args)
{
//if file association done with Arguments %1 as per forum post above
//you file path should be in args[0]
string filePath = null;
if(args != null && args.Length > 0)
filePath = args[0];
}
For a WPF application you'll need to handle that in the StartUp event for your Application
void App_Startup(object sender, StartupEventArgs e)
{
string filePath = null;
if ((e.Args != null) && (e.Args.Length > 0))
{
filePath = e.Args[0];
}
}
