Error when previewing MVC views in Visual Studio 2015

Question

When I preview the code of one of my MVC views in Visual Studio 2015 I get an error popup.

It says

The 'Microsoft Data Transformation Service Designer' package did not load correctly.

The problem may have been caused by a configuration change or by the installation of another extension. You can get more info by viewing ActivityLog.xml

I have tried reinstalling Visual Studio this makes no difference. I have also tried looking at different MVC projects they all display this error.

Anyone have any ideas to fix this error. My projects build fine so I can just ignore it but I would prefer not to if possible.

UPDATE

This is the contents of ActivityLog.xml

<type>Error</type>
    <source>VisualStudio</source>

Maybe this helps to reset VS, delete the contents from the following folders:

C:\Users{user}\AppData\Local\Microsoft\VisualStudio

C:\Users{user}\AppData\Local\Microsoft\VSCommon

Sometimes, you need to go to:

[x64] C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE

[x86] C:\Program Files\Microsoft Visual Studio 14.0\Common7\IDE

and run devenv /resetuserdata.

Expect, that all of your user settings such as Visual Studio layout, linked Microsoft account or start page dissapear.
