+Summary: methods w/ "params" in interfaces being called from a dll
+
+When you make an interface with a method that has "params object[] foo" in 
+the parameter list, compile it to a dll then implement it in another 
+place, the "params" keyword gets ignored!  Here is an example I used to 
+reproduce this (if the interface exists in the same dll as its 
+implementation or at least the same file, this works fine):
+
+
+// FIRST FILE (compile after you have compiled the dll with the second 
+file)
+
+using System;
+
+namespace foo {
+
+using bar;
+
+public class A {
+
+static void Main () {
+
+string moo = "moo";
+C t = new B();
+B s = new B();
+
+t.test(3,moo);
+t.test(3);
+s.test(3,moo);
+s.test(3);
+}
+}
+
+public class B:C {
+public void test (int c,params object[] args) {
+Console.WriteLine(c);
+}
+}
+}
+
+// SECOND FILE (compile this to a DLL)
+
+namespace bar {
+
+public interface C {
+
+void test (int c, params object[] args);
+
+}
+}
+
+// ERROR!
+file1.cs(18) error CS1503: Argument 1: Cannot convert from 'string' 
+to 'object[]'
+file1.cs(18) error CS1501: No overload for method `test' takes `2' 
+arguments
+file1.cs(18) error CS8006: Could not find any applicable function for this 
+argument list
+file1.cs(19) error CS1501: No overload for method `test' takes `1' 
+arguments
+file1.cs(19) error CS8006: Could not find any applicable function for this 
+argument list
