.NET simplifies interoperability between languages and
specifically, for web based services. Essentially the .NET
framework consists of the CLR (common language runtime), CTS
(common type system), CLS (common language system), and IL
(intermediate language).
The CLR consists of a number of resources provided to .NET
applications such as the security model, type system and .NET
classes (c.f. Java classes). The CTS is the range of all
types that .NET understands although it is not necessarily the
case that a .NET program will understand all of these types.
The CLS however is a subset of the CTS which all .NET
languages must support: any two .NET languages can
interoperate via. the CLS.
All .NET languages are at some stage compiled into the IL, a
byte-code like language. However unlike a standard Java run
time environment, the IL is converted to
machine code either
.NET's main weakness is that Microsoft have ignored the

use in many
enterprise environments. However there is
