Q & A

3. What is .NET? It is huge, It is software
Provides an software environment to develop and execute modern applications
Like E-Business, Grid Computing, Web Services, Utilility computing, Autonomic computing, …

4. What is .NET? Competitive products include J2EE and IBM Websphere
IBM has defined e-business on demand as an enterprise whose business processes -- integrated end-to-end across the company and with key partners, suppliers, and customers -- can respond with speed to any customer demand, market opportunity, or external threat.

5. What is .NET?
This new software model integrates horizontally to link data, legacy systems, and custom applications, and this integration requires new levels of data integrity and transaction processing

6. What is .Net?
It allows an enterprise to connect with other enterprises, other business processes, other applications, and billions of pervasive computing devices
Open specifications and industry standards are the only realistic way that all of this can connect

7. What is .Net?
Grid computing allows distributed computing resources to be shared and managed as if they were one, large, virtual computer – like water, electricity, gas
Think of the water supply – its completely virtualized. Our interface is a water spigot!
See Scientific American, March 2003

8. What is .Net? Autonomic computing
Autonomic systems will self-manage, self- protect, balance workloads, install device drivers, and upgrade software
See Scientific American, June 2003

9. What is .Net?
Microsoft .NET comprises most of these concepts, and is built upon …
The .NET Framework
Microsoft Visual Studio® .NET
Servers like Microsoft Windows® Server 2003, Microsoft SQL Server™, and Microsoft BizTalk® Server

10. What is .NET
Client software, such as Windows XP, Windows CE, and Microsoft Office XP
The .NET Framework is an integral Windows component for building and running the next generation of software applications and Web services

11. .NET Framework Data and XML Classes Base Framework Classes

Common Language Runtime

12. The .NET Framework 20 different programming languages
Plumbing for developing software built in, enabling developers to focus on the core business logic code
Easier to build, deploy, and administer secure, robust, high performance applications

13. The .NET Framework Common Language Runtime or CLR is the core of .NET
Like an operating system running on another operating system
Like Java Virtual Machine, or the VB runtime
Abstracts the operating system even more
Windows itself is to close to the hardware
Is portable in theory (BSD Unix)

15. CLR The CLR is different
A .NET compiler generates binary executable software in a p-code format called Common Intermediate Language or CIL
At runtime the CLR re-compiles or JIT- compiles (Just In Time) the CIL into native code such as x86 machine language. 

16. CLR
“Managed” code runs in the native machine language of the system on which it is launched
The first invocation of an assembly is cached in its native machine code for subsequent invocations

17. Framework Class Library FCL
Framework Class Library or FCL
The FCL contains hundreds of classes
Classes pervade every aspect of .NET

18. Framework Class Library FCL
Framework Class Library reflects .NET’s object-oriented nature.
Most objects are extensible through class inheritance and other interesting .NET techniques
The FCL is one of the most extensive class libraries 

19. Base Framework Classes

20. FCL - Base Classes Base classes provide standard functionality
Input/output, string manipulation, security management, network
Communications, thread management, text management
User interface design features.

21. Data and XML Classes Data and XML Classes Base Framework Classes

22. FCL - Data and XML Classes
ADO.NET classes enable developers to interact with data accessed in the form of XML through the OLE DB, ODBC, Oracle, and SQL Server interfaces
XML classes enable XML manipulation, searching, and translations

23. ASP.Net and Window Forms

24. FCL - ASP.NET classes
The ASP.NET classes support the development of Web-based applications and Web services.
Web Forms are analogous to Windows Forms and the design time and execution environments look and feel very much the same

25. FCL – Windows Forms
The Windows Forms classes support the development of desktop-based smart client applications

26. .NET Framework
Class libraries provide a common, consistent development interface across all languages supported by the .NET Framework
CLR and the .NET Frameworks allow the seamless reuse of code written in any supported language
But also allows the components to be extended in another language

27. .NET Framework The .NET Framework is freely downloadable
ork/downloads/default.aspxs
Its about 23 MB
Once installed, you can run any .NET application

28. Building .NET Applications
The .NET Frameworks contains a collection of tools and compilers to generate .NET applications
MicroSoft provides C#, VB.NET, C++, and J#
There are at least 20 other compilers from other sources.
You can generate .NET apps with just the Framework.

29. Visual Studio .NET
However, to be productive, most developers use Visual Studio .NET
Comprises a single Integrated Development Environment for the Framework Classes and all .NET languages
Many, many tools to develop apps
Application delivery packaging

30. How do get started?
Develop on Windows 2000 or Server, Windows XP Professional or Server
Target these same platforms
Make sure Internet Information Services are installed and functioning
Buy and install Visual Studio .Net
Install your GeoMedia products

31. How do get started?
VB6 and C++ 6 will run just fine as well at the same time
Utilize the many free or cheap MS local technical sessions
Consult the many technical manuals available at your local book store
Utilize the Microsoft .NET online areas, and other services like CodeProject
MSDN Magazine

32. What language to use
Probably currently easier to use VB.Net than C# for GeoMedia apps
More enterprise type apps and examples seem to be biased towards C#. MSDN magazine seems to be more C# oriented
Most of the Framework and Visual Studio .NET written in C#
C# apps are a little faster

33. What language to use If you are a C or C++ developer, C# for sure
If you’ve always wanted to learn C++, use C#. In many ways, C# is a leaner easier C++
You can still write standard MFC and ATL C++ applications.

34. What about .NET and GeoMedia?
Version 4 and 5 GeoMedia seem to work pretty well with .NET
Version 4 GeoMediaWebMap will not
Not all objects seem to work with .NET
Customer requirements will probably dictate the time when all objects will work well with .NET

35. What about .NET and GeoMedia?
In the mean time, I would recommend getting started on small scale apps
Also applications, particularly Web Apps, in the portions were GeoMedia is not utilized
A major focus in .NET is Internet oriented applications and WebServices

36. What about .NET and GeoMedia?
COM versus .NET
COM will not disappear, but .NET Framework is a bigger, better, faster COM
But .NET provides many tools/classes for working with legacy COM object hierarchies like GeoMedia
What is Intergraph’s direction?

37. City View Example .Net truly is a Rapid Develop Environment
CityView is a perfect example of the power of .NET to utilize Web Services to create interesting applications.
Code…

38. Web Services – City View

39. GeoMedia Example
A Water Company wants to maintain an atlas sheet approach for the maintenance crews
Various interface mechanisms and plotting mechanisms are based on a standard tiling scheme ( 3000’ X 2000’ )
Sheets are being added somewhat frequently.

40. GeoMedia Example
Need a tool to generate all the interface/generation mechanisms from single source

41. ASP.Net Example
Our Web applications tend to have many interface mechanisms for map navigation
ASP.NET provides a rich environment for extending existing controls
And debugging ASP really works!
