CSharpFixFormat for Visual Studio Code

This extension helps to format C# code. When OmniSharp will support all features - will be deprecated.

C#5 / C#6 / C#7 support limited and some features not implemented, because main goal of this extension - formatting C#3.5 / C#4 sources of UnityEngine projects on MacOS, nothing more.

If you need full format support of last C# version - better to write issue about proper formatting at Omnisharp extension repo.


This extension not dependent on any 3dparty extensions (even omnisharp) and works as standalone formatting solution for current C#-file.


All features available through standard "format document" hotkey after opening C# file.

  • Sort usings in alphabetical order. Doubles will be removed automatically.
  • Fix indent size for all lines (omnisharp still cant do it for wrapped lines).
  • Cleanup empty lines with allowed limit in row.

Extension provides formatting in batch mode through folder context menu at explorer window.

Special flags

Formatting can be ignored for any code with wrapping to directives:

/* fixformat ignore:start */
var test    =        i().  willNotBeFormatted     []   ;
/* fixformat ignore:end */

Known issues

Multilined constrained generics not supported:

    where T : class

Suggestion - put constraints on one line:

class<T> where T : class

Multiline initialization for new instance as parameter for method will not be formatted correctly:

TestMethod (new TestClass {
    a = 10,
        b = 20

Suggestion - split variable declaration and method calling:

var t = new TestClass {
    a = 10,
    b = 20
TestMethod (t);

Initialization with nested "{ }" can be formatted wrong:


new System.Collections.Generic.Dictionary<string, string>() {
    { "", "" },
    { "", "" },
    { "", "" },


new System.Collections.Generic.Dictionary<string, string>()	{
    { "", "" }, { "", "" }, { "", "" },

Suggestion - add comment for each item in initialization:

new System.Collections.Generic.Dictionary<string, string>() {
    // Item 1 description.
    { "", "" },
    // Item 2 description.
    { "", "" },
    // Item 3 description.
    { "", "" },

Named parameters with string consts as values can be formatted wrong:


var test = Test(
    name: "Test name",
    amount: 1,
    type: TestType.Type1


var test = Test(
    name : "Test name",
    amount : 1,
    type : TestType.Type1

Suggestion - extract string values as consts:

const string TestName = "Test name";
var test = Test(
    name: TestName,
    amount: 1,
    type: TestType.Type1

Сoexistence with the omnisharp-vscode extension

On each run this extension checks that omnisharp-vscode extension (if installed) will use "csharp.format.enable": false option for disabling builtin format feature. This extension will not work correctly with activated omnisharp-vscode format feature - it's why user should fix option manually or automatically with autofix suggestion.

After removing the extension, user should manually restores this option to "onisharp-vscode": true for enabling format feature and restart editor then.
