Blend showing error

[MōnoSimeone]

Hi, I'm new to the web-dev side and been working on a silverlight project.

I had installed the 2.0 api and everything seemed ok. Then I installed the 2.2 api and my projects now open in Blend with an error - see attached.

I assume this means I need to correct references or delete previous api files. I just don't know. Can someone please explain how to remedy the error.

Thanks,
M.

You need to update your project references to API assembly. You can also read up on some Getting Started docs from our resource page: http://help.arcgis.com/en/webapi/silverlight/help/index.html#//016600000013000000.htm
