I have the following line of code:

var connectionString = configItems.Find(item => item.Name.ToLowerInvariant() == "connectionstring");

VS 2010 Code analysis is telling me the following:

Warning 7 CA1308 : Microsoft.Globalization : In method ... replace the call to 'string.ToLowerInvariant()' with String.ToUpperInvariant().

Does this mean ToUpperInvariant() is more reliable?

Dynamic Type to do away with Reflection

The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
