Visual Studio Syntax Highlighting for C# Files

Environment: Visual Studio and C#

Here are the instructions necessary to have Visual Studio syntax-highlight your C# files.

1. Locate the following key in your registry (using regedit or any other registry editor):

   HKEY_CURRENT_USER\Software\Microsoft\DevStudio\6.0\Text Editor\Tabs/Language Settings\C/C++\FileExtensions

   This value will contain a value like the following:

   cpp;cxx;c;h;hxx;hpp;inl;tlh;tli;rc;rc2

   Simply add the .cs extension to the end as in this example:

   cpp;cxx;c;h;hxx;hpp;inl;tlh;tli;rc;rc2;cs

2. Download the usertype.dat file (at the bottom of this document)
   and copy it to the same directory as msdev.exe
   (Visual Studio editor) (By default this will be
   c:\program files\microsoft visual studio\common\msdev98\bin). This file contains all the C# keywords
