PROBLEM
VB Projects cannot be built due to the usage of the Global Namespace. This happens when classes are held in different than the root namespace in Visual Basic projects.

Typical errors received on build are:

When you open the report's Designer.VB file you will find that lines like:
are underlined as error lines.
Changing the line as follows should resolve the error:

The issue is that changing a setting of report will cause the Reporting engine to re-serialize the code in the report's Designer.VB file without the custom Global namespace.

SOLUTION 
Open the project's Properties in Visual Studio and remove the Root Namespace, leave it blank. This will let you skip the Global namespace on specifying types.
