Converting Project Errors

Question

I have converted a project from VB.Net to c#.net and I have been slowly working through the errors from 113 now down to just 27.

Now I am stuck on the errros that are as follows

Inconsistent accessibility: field type 'Bla1.Bla1.Bla1<Bla2.Bla2.Bla2>' is less accessible than field 'Bla2.Bla2.Bla2'

I'm guessing there is someone here that can help me fix these!

Thanks in advance
