How can I tell if an object's type is Nullable<T> using reflection?

If I have a Type, is there some easy way to tell that it represents a nullable value type using Reflection? Ideally something a little cleaner (and more correct) than: static bool IsNullable(Type type) { return type.IsValueType && type.Name.StartsWith("Nullable"); } ...

Telling the difference between two large pieces of text

What would be the best way to compare big paragraphs of text in order to tell the differences apart. For example string A and string B are the same except for a few missing words, how would I highlight these? Originally I thought of breaking it down into word arrays, and comparing the elements.

.NET Json Serialization, JSON_MaxJsonLengthExceeded when passing 2 Megabytes of data.

What sets the JSON buffer length other than web.config or creating an instance of the JavaScriptSerializer?

Storage and Logical Model in Entity Framework
