How to have comments in IntelliSense for function in Visual Studio

Question

In Visual Studio and C   when using a built in function such as ToString    IntelliSense shows a yellow box explaining what it does        How can I have that for functions and properties I write

All these others answers make sense  but are incomplete  Visual Studio will process XML comments but you have to turn them on  Here s how to do that   Intellisense will use XML comments you enter in your source code  but you must have them enabled through Visual Studio Options  Go to Tools   Options   Text Editor  For Visual Basic  enable the Advanced   Generate XML documentation comments for     setting  For C   enable the Advanced   Generate XML documentation comments for     setting  Intellisense will use the summary comments when entered  They will be available from other projects after the referenced project is compiled   To create external documentation  you need to generate an XML file through the Project Settings   Build   XML documentation file  path that controls the compiler s  doc option  You will need an external tool that will take the XML file as input and generate the documentation in your choice of output formats   Be aware that generating the XML file can noticeably increase your compile time

Also the visual studio add-in ghost doc will attempt to create and fill-in the header comments from your function name

In CSharp  If you create the method function outline with it s Parms  then when you add the three forward slashes it will auto generate the summary and parms section   So I put in    public string myMethod string sImput1  int iInput2        I then put the three     before it and Visual Studio s gave me this        lt summary gt            lt  summary gt       lt param name  sImput1  gt  lt  param gt       lt param name  iInput2  gt  lt  param gt       lt returns gt  lt  returns gt  public string myMethod string sImput1  int iInput2

To generate an area where you can specify a description for the function and each parameter for the function  type the following on the line before your function and hit Enter    C        VB        See Recommended Tags for Documentation Comments  C  Programming Guide  for more info on the structured content you can include in these comments

use     to begin each line of the comment and have the comment contain the appropriate xml for the meta data reader       lt summary gt      this method says hello     lt  summary gt  public void SayHello      Although personally  I believe that these comments are usually misguided  unless you are developing classes where the code cannot be read by its consumers

Those are called XML Comments  They have been a part of Visual Studio since forever   You can make your documentation process easier by using GhostDoc  a free add-in for Visual Studio which generates XML-doc comments for you  Just place your caret on the method property you want to document  and press Ctrl-Shift-D   Here s an example from one of my posts   Hope that helps

What you need is xml comments - basically  they follow this syntax  as vaguely described by Solmead    C       lt summary gt     This is a description of my function      lt  summary gt  string myFunction          return  blah       VB      lt summary gt     This is a description of my function      lt  summary gt  Function myFunction   As String     Return  blah  End Function
