# Referencing Other Assemblies in Scripting Solutions
  The [!INCLUDE[msCoName](../../includes/msconame-md.md)] [!INCLUDE[dnprdnshort](../../includes/dnprdnshort-md.md)] class library provides the script developer with a powerful set of tools for implementing custom functionality in [!INCLUDE[ssISnoversion](../../includes/ssisnoversion-md.md)] packages. The Script task and the Script component can also use custom managed assemblies.

> [!NOTE]
>  To enable your packages to use the objects and methods from a Web service, use the **Add Web Reference** command available in [!INCLUDE[msCoName](../../includes/msconame-md.md)][!INCLUDE[vsprvs](../../includes/vsprvs-md.md)] Tools for Applications (VSTA). In earlier versions of [!INCLUDE[ssISnoversion](../../includes/ssisnoversion-md.md)], you had to generate a proxy class to use a Web service.

## Using a Managed Assembly
 For [!INCLUDE[ssISnoversion](../../includes/ssisnoversion-md.md)] to find a managed assembly at design time, you must do the following steps:

1.  Store the managed assembly in any folder on your computer.

    > [!NOTE]
    >  In earlier versions of [!INCLUDE[ssISnoversion](../../includes/ssisnoversion-md.md)], you could only add a reference to a managed assembly that was stored in the %windir%\Microsoft.NET\Framework\vx.x.xxxxx folder or the %ProgramFiles%\Microsoft SQL Server\100\SDK\Assemblies folder.

2.  Add a reference to the managed assembly.

     To add the reference, in VSTA, in the **Add Reference** dialog box, on the **Browse** tab, locate and add the managed assembly.

 For [!INCLUDE[ssISnoversion](../../includes/ssisnoversion-md.md)] to find the managed assembly at run time, you must do the following steps:

1.  Sign the managed assembly with a strong name.

2.  Install the assembly in the global assembly cache on the computer on which the package is run.

     For more information, see [Building, Deploying, and Debugging Custom Objects](../extending-packages-custom-objects/building-deploying-and-debugging-custom-objects.md).

## Using the Microsoft .NET Framework Class Library
 The Script task and the Script component can take advantage of all the other objects and functionality exposed by the [!INCLUDE[dnprdnshort](../../includes/dnprdnshort-md.md)] class library. For example, by using the [!INCLUDE[dnprdnshort](../../includes/dnprdnshort-md.md)], you can retrieve information about your environment and interact with the computer that is running the package.

 This list describes several of the more frequently used [!INCLUDE[dnprdnshort](../../includes/dnprdnshort-md.md)] classes:

-   `System.Data` Contains the ADO.NET architecture.

-   `System.IO` Provides an interface to the file system and streams.

-   `System.Windows.Forms` Provides form creation.

-   `System.Text.RegularExpressions` Provides classes for working with regular expressions.

-   `System.Environment` Returns information about the local computer, the current user, and computer and user settings.

-   `System.Net` Provides network communications.

-   `System.DirectoryServices` Exposes Active Directory.

-   `System.Drawing` Provides extensive image manipulation libraries.

-   `System.Threading` Enables multithreaded programming.

 For more information about the [!INCLUDE[dnprdnshort](../../includes/dnprdnshort-md.md)], see the MSDN Library.
