[Other Languages]

Languages Focus

Common or primary file extensions used (not a complete list, just the basics).

C#:

Common source code file extensions include:

.SLN - Solution File. Contains solution specific information such as links to the projects within this solution.
.CSPROJ - C# Project File. Contains project specific information. When you add a file containing one or more classes, it is added to this file.
.CS - C# source file.
.Designer.CS - C# form file (a text resource file).

Syntax Example:

//Sample code snippet from the .csproj project file:

<ItemGroup>
  <Compile Include="Cyborg.cs" />
  <Compile Include="Cyborg600.cs" />
  <Compile Include="Form1.cs">
    <SubType>Form</SubType>
  </Compile>

  //...

JavaScript:

.js is the common standard for browser-side JavaScript and .jsp is the common standard for server-side JavaScript.
