Consider specifying the type arguments explicitly. Generic Types Raw Types Generic Methods Bounded Type Parameters Generic Methods and Bounded Type Parameters Generics, Inheritance, and Subtypes Type Inference Wildcards Upper Bounded Wildcards Unbounded Wildcards Lower Bounded Wildcards Wildcards Thus, in Java SE 7, you must specify the value of the value of the type argument as follows: processStringList(Collections.emptyList()); This is no longer necessary in Java SE 8.

But in the VB version it's not being supplied: BinSerial.BinaryFileDeSerialize(filename) It still needs to be, for the same reason: BinSerial.BinaryFileDeSerialize(Of Animal)(filename) share|improve this answer answered Aug 6 '15 at 19:31 David When you do this, the compiler attempts to infer the type of each type argument from the context of your call. Give us your feedback.

So after adding Option Explicit, you have to add type declaration: Dim animals As List(Of Animal) = BinSerial.BinaryFileDeSerialize(Of Animal)(filename) You immediately get better overview of what you are doing. Integer and Date do not convert to the same type. 'targetMethod(19, #3/4/2007#) End Sub Sub targetMethod(Of T)(ByVal p1 As T, ByVal p2 As T) End Sub End Module Error ID: BC36660 Now the compiler can infer the generic return types. We appreciate your feedback.
