Visual Studio 2010 - as is.
|
Visual Studio 2008 - install SP1 and Patch KB958502.
|
|
linq-vsdoc.js(or jquery.linq-vsdoc.js) puts in same directory.

if not html then write xml referrence tag on top.
|
for example

|
|
for Windows Script Host

|
create wsf file.
|
example
|
|
<job id="Main">
|
<script language="JScript" src="linq.js"></script>
|
<script language="JScript">
|
var dir = WScript.CreateObject("Scripting.FileSystemObject").GetFolder("C:\\");
|
|
var itemNames = Enumerable.From(dir.SubFolders)
|
.Concat(dir.Files)
|
.Select("$.Name")
|
.ToArray();
|
</script>
|
</job>

How to use CodeSnippets
|
---
|
open Visual Studio 2010's Code Snippet Manager(Ctrl+K, Ctrl+B)
|
click import button and select snippets/*.snippet
|
|
func0 = function () { return /*cursor*/}
|
func1 = function (x) { return /*cursor*/}
|
func2 = function (x, y) { return /*cursor*/}
|
action0 = function () { /*cursor*/}
|
action1 = function (x) { /*cursor*/}
|
action2 = function (x, y) { /*cursor*/}
|
efrom = Enumerable.From()
|
erange = Enumerable.Range()
|
jqfrom = $.Enumerable.From()
|
jqrange = $.Enumerable.Range()
