1.	Native Support for Developing Mobile Web Applications 
2.	Enable Execution of Windows Forms Assemblies Originating
from the Internet
Assemblies originating from the Internet zone?for example,
Microsoft Windows? Forms controls embedded in an
Internet-based Web page or Windows Forms assemblies hosted
on an Internet Web server and loaded either through the Web
browser or programmatically using the
System.Reflection.Assembly.LoadFrom() method?now receive
sufficient permission to execute in a semi-trusted manner.
Default security policy has been changed so that assemblies
assigned by the common language runtime (CLR) to the
Internet zone code group now receive the constrained
permissions associated with the Internet permission set. In
the .NET Framework 1.0 Service Pack 1 and Service Pack 2,
such applications received the permissions associated with
the Nothing permission set and could not execute. 
3.	Enable Code Access Security for ASP.NET Applications
Systems administrators can now use code access security to
further lock down the permissions granted to ASP.NET Web
applications and Web services. Although the operating system
account under which an application runs imposes security
restrictions on the application, the code access security
system of the CLR can enforce additional restrictions on
selected application resources based on policies specified
by systems administrators. You can use this feature in a
shared server environment (such as an Internet service
provider (ISP) hosting multiple Web applications on one
server) to isolate separate applications from one another,
as well as with stand-alone servers where you want
applications to run with the minimum necessary privileges. 
4.	Native Support for Communicating with ODBC and Oracle
Databases 
5.	Unified Programming Model for Smart Client Application
Development
The Microsoft .NET Compact Framework brings the CLR, Windows
Forms controls, and other .NET Framework features to small
devices. The .NET Compact Framework supports a large subset
of the .NET Framework class library optimized for small
devices. 
6.	Support for IPv6
The .NET Framework 1.1 supports the emerging update to the
Internet Protocol, commonly referred to as IP version 6, or
simply IPv6. This protocol is designed to significantly
increase the address space used to identify communication
endpoints in the Internet to accommodate its ongoing growth.
