+Summary: nunit20 exposes array casting problem
+
+The following code, in mcs/framework/TestCaseBuilder.cs, generates an
+InvalidCastException:
+
+private static string GetIgnoreReason(MethodInfo methodToCheck)
+{
+   Type ignoreMethodAttribute = typeof(NUnit.Framework.IgnoreAttribute);
+   NUnit.Framework.IgnoreAttribute[] attributes =
+(NUnit.Framework.IgnoreAttribute[])methodToCheck.GetCustomAttributes(ignoreMethodAttribute,
+false);
+   string result = "no reason";
+
+   if(attributes.Length > 0)
+      result = attributes[0].Reason;
+
+   return result;
+}
+
+If I change it to the following, it works:
+
+private static string GetIgnoreReason(MethodInfo methodToCheck)
+{
+   Type ignoreMethodAttribute = typeof(NUnit.Framework.IgnoreAttribute);
+   object[] attributes =
+methodToCheck.GetCustomAttributes(ignoreMethodAttribute, false);
+   string result = "no reason";
+
+   if(attributes.Length > 0)
+      result = ((NUnit.Framework.IgnoreAttribute) attributes[0]).Reason;
+
+   return result;
+}
+
+There's no reason why the top cast should fail while the second one works.
