# SMO Object Model Namespaces
  [!INCLUDE[ssNoVersion](../../includes/ssnoversion-md.md)] Management Objects (SMO) has various namespaces. The different namespaces represent different areas of functionality within SMO.  
  
 In [!INCLUDE[ssCurrent](../../includes/sscurrent-md.md)], the SMO assemblies are located in the C:\Program Files\Microsoft SQL Server\130\SDK\Assemblies\ folder.  
  
## Namespaces  
 The SMO namespaces are:  
  
|Class|Function|  
|-----------|--------------|  
|<xref:Microsoft.SqlServer.Management.Smo>|Contains instance classes, utility classes, and enumerations that are used to programmatically manipulate [!INCLUDE[msCoName](../../includes/msconame-md.md)][!INCLUDE[ssNoVersion](../../includes/ssnoversion-md.md)].|  
|<xref:Microsoft.SqlServer.Management.Common>|Contains the classes that are common to Replication Management Objects (RMO) and SMO, such as connection classes.|  
|<xref:Microsoft.SqlServer.Management.Smo.Agent>|Contains classes that represent the [!INCLUDE[ssNoVersion](../../includes/ssnoversion-md.md)] Agent.|  
|<xref:Microsoft.SqlServer.Management.Smo.Wmi>|Contains classes that represent the WMI Provider.|
