+Summary: UnixRegistryApi.DeleteValue throwing exception
+
+Here is the original email. This is blocking the tests for NUnit from
+running on Mono/Linux because of the error being thrown.
+
+Cory:
+
+--------------------------
+
+Hi All,
+
+I'm building NUnit on Linux with the latest version of Mono (.14) and am
+getting the following:
+
+     [exec] 5) NUnit.Util.Tests.NUnitRegistryTests.TestClearRoutines :
+System.InvalidCastException : Cannot cast from source type to destination type.
+     [exec] in <0x00095> Microsoft.Win32.UnixRegistryApi:DeleteValue
+(Microsoft.Win32.RegistryKey rkey, System.String value, Boolean
+throw_if_missing)
+     [exec] in <0x00038> Microsoft.Win32.RegistryKey:DeleteValue
+(System.String value, Boolean shouldThrowWhenKeyMissing)
+     [exec] in <0x0000f> Microsoft.Win32.RegistryKey:DeleteValue
+(System.String value)
+     [exec] in (wrapper remoting-invoke-with-check)
+Microsoft.Win32.RegistryKey:DeleteValue (string)
+     [exec] in <0x00070> NUnit.Util.NUnitRegistry:ClearKey
+(Microsoft.Win32.RegistryKey key)
+     [exec] in <0x00030> NUnit.Util.NUnitRegistry:ClearSubKey
+(Microsoft.Win32.RegistryKey baseKey, System.String subKey)
+     [exec] in <0x00023> NUnit.Util.NUnitRegistry:ClearTestKeys ()
+     [exec] in <0x00139>
+NUnit.Util.Tests.NUnitRegistryTests:TestClearRoutines ()
+     [exec] in <0x00000> <unknown method>
+     [exec] in (wrapper managed-to-native)
+System.Reflection.MonoMethod:InternalInvoke (object,object[])
+     [exec] in <0x0008d> System.Reflection.MonoMethod:Invoke (System.Object
+obj, BindingFlags invokeAttr, System.Reflection.Binder binder,
+System.Object[] parameters, System.Globalization.CultureInfo culture)
+
+The code is pretty straightforward:
+
+public static void ClearKey( RegistryKey key )
+{
+    foreach( string name in key.GetValueNames() )
+        key.DeleteValue( name );
+     foreach( string name in key.GetSubKeyNames() )
+        key.DeleteSubKeyTree( name );
+}
+
+
+Does this look to you all to be a bug in the UnixRegistryApi, or something
+innocuous like an invalid name? The code that is calling ClearKey verifies
+that the RegistryKey it is passing in isn't null. Any pointers would be
+appreciated. Thanks!
