The Trash Destination and this article came from early experiences of using SSIS and community feedback at the time. When developing a package it is very useful to have a destination adapter that does nothing but consume rows with no setup requirement. You often want run a package part way through development, or just add a path so you can set a Data Viewer. There are stock tasks that can be used, but with the Trash Destination all columns are treated as selected automatically (usage type of read-only), so the pipeline knows they are required. It is also obvious that this is for development or diagnostic purposes, and is clearly not a part of the functional design of the package. It is also ideal for just playing around and exploring concepts in SSIS, and is often used in conjunction with the Data Generator Source. Using these two components it is easy to setup a test of an expression in the Derived Column Transformation for example. The Data Generator Source provides some dummy data, and the Trash Destination allows you to anchor the output path and set a Data Viewer to examine the results.
It can also be used when performance tuning packages. It is a consistent and known quantity that has no external influences, so it is ideal as a destination when breaking the data flow into sections to isolate a bottleneck.
The adapter is really simple to use and requires no setup. Simply drop it onto the pipeline designer and use it to terminate your data flow path.
Installation
The component is provided as an MSI file which you can download and run to install it. This simply places the files on disk in the correct locations and also installs the assemblies in the Global Assembly Cache as per Microsoft’s recommendations.
You may need to restart the SQL Server Integration Services service, as this caches information about what components are installed, as well as restarting any open instances of Business Intelligence Development Studio (BIDS) / Visual Studio that you may be using to build your SSIS packages.
Finally you will have to add the transformation to the Visual Studio toolbox manually. Right-click the toolbox, and select Choose Items.... Select the SSIS Data Flow Items tab, and then check the Trash Destination transformation in the Choose Toolbox Items window. This process has been described in detail in the related FAQ entry for How do I install a task or transform component?
We recommend you follow best practice and apply the current Microsoft SQL Server Service pack to your SQL Server servers and workstations.
Downloads
The Trash Destination is available for both SQL Server 2005 and SQL Server 2008. Please choose the version to match your SQL Server version, or you can install both versions and use them side by side if you have both SQL Server 2005 and SQL Server 2008 installed.

The data flow object "Konesans ..." is not installed correctly on this computer, this usually indicates that the internal cache of SSIS components needs to be updated. This is held by the SSIS service, so you need restart the the SQL Server Integration Services service. You can do this from the Services applet in Control Panel or Administrative Tools in Windows. You can also restart the computer if you prefer. You may also need to restart any current instances of Business Intelligence Development Studio (BIDS) / Visual Studio that you may be using to build your SSIS packages.
The full error message is shown below for reference:
