Bottom line AJAX is bad for SEO!
For publicly facing company websites, were SEO important, stick with the server side scripting such as ASP.NET, PHP, Ruby on Rails and others.
I am not mentioning static HTML pages here since medium and big size companies most likely will have data driven web site.

If you are building Line of Service business application AJAX will only make your application better.
Do not think twice learn it well and use it.

If you absolutely have to use AJAX follow "Unobtrusive JavaScript" pattern.
AJAX is great tool when used for proper application types.

Here is my prediction -> 3 years from now Search engines will learn to understand and properly index and rank RIA/AJAX/FLASH/Silverlight/Flex/Put your faviorite client side technology here. Until then ...

Every company needs them. Every company wants them. Every company want to spend money on custom Content Management System that they can call their own. -->


Next time you try to reinvent CMS stop and first take a look at existing CMS systems that very liberally licensed. If you cannot use them at least take a look at their architecture. It will give you a good starting point.

• www.dotnetnuke.com "DotNetNuke^® is a free, Open Source Framework ideal for creating Enterprise Web Applications..."
• http://umbraco.org/ "Umbraco - the simple, flexible and friendly ASP.NET CMS..."
• www.mojoportal.com "mojoPortal, is an open source web site framework and content management system..."
• http://www.cuyahoga-project.org/ "Cuyahoga is an open source .NET web site framework..."
• http://n2cms.com/ "N2 is a lightweight CMS framework that focuses on ease of use and developer experience..."
• http://www.vwd-cms.com/ "VWD-CMS is a free, open source content management system for ASP.NET..."
• www.axinom.com/en_axcms_home.AxCMS "Axinom Enterprise Content Management System AxCMS.net 7 is a award-winning content management system..."

I was just concentrating on the CMS that based on ASP.NET and had a good web presence and documentation.
----->
After some review of architectures Cuyahoga is leading this list for me. N2 is very close behind the Cuyahoga as of March 02, 2008.
When new frameworks come in to play I will review them and reassess.

I am developing a web service for a customer. The service has a method, that
returns an array of Forms. Each form has a Name property of Type String.

The customer wants the contract to specify, thath the name is mandatory and
not nullable. To reflect this, they want the xml in the wsdl (the Form part)
to look similar to this:

<xs:complexType name="Form">
<xs:sequence>
...
<xs:element minoccurs="1" maxoccurs="1" name="Name" nillable="false" type="xs:string">
...

So, minOccurs should be 1 and nillable should be false (or omitted), to
ensure the value is present and not null.

No matter how I go about this, however, I cannot make the wsdl generate the
desired values. I have tried to do contract-first development using WSCF from
thinktecture, and have the schema dictate the above values for minOccurs and
nillable, but this approach has not remedied the problem.

Is it at all possible to do what I want using .Net and Visual Studio 2005? I
hope my problem is described adequately, otherwise please request more
information. Any help is greatly appreciated.

---

Regarding on the webservice class property definition problem you
mentioned, here are some of my understanding and suggestion:

1. .NET webservice will always generate the xsd scheme for class property
as below:

** for value type(primitive types or struct), it will use minOccurs="1"
since value type will always be assigned a value(doesn't have null value
unless you use nullable type).

** for reference type(such as normal class), it will use minOccurs="0"
since value type will always support null value, the "string" type in your
case is just conform to this policy.

So far this rule is not changable in our custom code(attribute).

2. Also, XML XSD schema definition's element definition doesn't 100%
completely identical to .NET(or OO ) class/type definition. For example, if
you have the following xsd schema

<element minOccurs="1" ..../>

you can not find a reference type to mapping it since reference type always
support null reference value. I think you can consider define a wrapper
class(which inherit from ValueType ), property of such type will be
automatically generated as minOccurs="1" in XSD schema. However, you still
need to ensure that any sub property of reference type(such as string) has
been supplied a value in your own code.
