Hello experts,
Today, I got the following error message when I was upgrading my TFD 2010 to TFS 2012. Is it the compatibility issue or something else? I want to resolve this issue and upgrade to a new version of TFS 2012. How can I fix it as soon as possible? Can anyone help me? Thanks in advance for any help.
Microsoft Visual Studio
There are no components in
'C:COB_TFSBuildToolsCOB.Cl.Workflow.dll’ that can be placed on
the toolbox.

Microsoft Visual Studio Component error occurred
It is recommended to remove any Beta products in question, when installing The  ''final'' version of the product. This prevents any failures during on running of the application.
Most of the time the beta removal kits/tools are released by Microsoft to completely remove any traces of the beta product even after uninstalling it. This ensures that the installation and usage of The  ''Final '' product will be smooth as possible.
So for example, Visual Studio 2009 removal kit is located and should be applied before installing the full final version of Visual Studio.
Be sure to give the system a reboot just incase, even if not prompted to.
