Hi folks,

When trying to create a DataSource in Visual Basic 2012 Ultimate, I get the below error. I have the database created and the tables etc. But just trying to create a DataSource.

unable to cast object of type 'System.Object[]' to Type 'system.ComponentModel.AttributeProviderAttribute[]

Has anyone experienced this before and know how to resolve it? I have searched Google etc and to very little result.
I have recreated the project again from scratch and still getting it.

Thanks in advance.

Hi Andrew.
Datatypes are all fine. ID is set to Int. Text Boxes are set to varchar(50) and large information textbox is set to text.

I have also opened another project I did last week with DataSources etc, and the same error popped up when loading the project.

Strange.
It seemed to have solved itself.
I closed down VS altogether, rebooted the laptop, opened VS again, opened an old project, which worked with DataSource and then opened the new project, where I was finally able to add a DataSource.

Hope this helps someone with a similar issue.
