SqlHelper is not Declared

Creating a new DNN module with SQL database connections I observed the error: SqlHelper’ is not declared, when compiling the SqlDataProvider project.

The full SqlDataProvider, SqlHelper’ is not declared, error details are:

Error    8    'SqlHelper' is not declared.
It may be inaccessible due to its protection level.
C:\inetpub\wwwroot\dnn7\website\DesktopModules\VNTweb\MyProject\Providers\DataProviders\SqlDataProvider\SqlDataProvider.vb

Reviewing the SqlDataProvider.vb file (associated with the SqlDataProvider project I found a spelling error in the imports reference for Microsoft.ApplicationBlocks.Data. Given below are the imports used.
