You need to specify the full assembly name:
Type type = Type.GetType("BusinessLayer.Report.Render.StudentHtmlWriter,
YourAssemblyName");
If your assembly is strong named, then you need to specify Version, Culture
and PublicKeyToken.
The reason this is happening is when no assembly name is specified on a
Type.GetType call, the runtime look in the calling assembly. If it can't be
find in the calling assembly it returns null.
