File Extensions (Cross Ref > Tool Basics)

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).

//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>

• .SLN - Solution File. Contains solution specific information such as links to the projects within this solution.
