So its wednesday and Im actually posting lunch time so tyhis covers the morning sessions.

First two sessions were the changes in ASP2.0 by Scott Guthrie, another practised speaker and extremely knowledgable on his subject.

Well I think were our out of jobs. Scott pretty much built a portal with almost zero code behind, just drag and drop and set the properties We might end up coding Data Layers for the rest of our dev lives.

ASP2.0 has got some great features and heres some.

XSD Designer - Create STD’s complete with Adaptor class in the desinger and embedded into the one XSD file a complete DAL in a box
No more mangled HTML

This goes further the designer support in whidbey is awsome all the niggly bits that pissed you off in the past are gone
No more event wiring disappearing (there is no event wiring in the code behind at all now, not sure I like that!)
Select something in designer, its selected in the html code
drap on tools into html view
select a tag in html view and you have access ot the properties window
New controls that can bind to any IEnumerable object, imagine binding a datagrid straight to the Provider class in your DAL
This comes complete with edit and update to a Business object to.
Master pages done properly with designer support
Designer support for user controls not just a grey box
Membership capabilities with roles based on a provider model so you can plug it into xml, sql, AD, or your own custom store this was used to demonstrate Personalisation.
Templates and skins - combined with CSS to give you flexibility over design, and switchable at run time.
Common tasks button on every control in a drop down menu on the designer (this is cool)
NO MORE PROJECT FILE - Team development can be easier ( I supose this means we have to re-structure our SS yet again though)
Deploy the whole damn lot to a DLL, no aspx’s, no asmx’s, no html nowt but a dll (if you need to set file/directory permissions then proxies are created for this purpose that you attach permissions to, but if you dont need to do that just delete them)

And loads more too much to remember all the little details but many of the things introduced I could use immediately.

Next Session was the one touch deployment a nice safe session detailing the improvements to click once deployment, I think there will be some headaches in the admin side of this but none you could not overcome, there is even ability to bootstrap dotnet 2.0 via this method. It looks cool but needs testing in a corp environment to see howit reacts to security etc but it seems vastly improved from the last v1 release.

Well thats it for now off to another session I am going to Wojtek’s sessino after all I don’t know what to expect but here goes.

This was a chalk and talk session, I had no real idea what a C&T session was but it was interesting. Don gets up and asks a load of questions from the audience and writes them down, in xml!. He sorts them into topics and proceeds to answer them.

The basis for the piece was the messaging infrastructure of webservices and future indigo messaging. Some questions were

1 x vs y vs z
2. http vs DCOM MSMQ
In this one he talked a little of .Net remoting and mentioned about it not being secure (perhaps you could role your own etc) and that the team who wrote it were not very big and they essentially had to rewrite dcom in no time at all so the whole tcp-binaryformatter was not a protocol that has had many man years on it, in fact why not just use DCOM its had thousands if not millions of man years worked on it ( there was more detail but I cant do him justice)

He says he will post these details to his blog with the questions and answers.

So what I will comment on was the talk in general, this was alively talk by an extremely well practised speaker. It was thoroughly enjoyable and with all the SAO zelousness (is that a word) a breathe of fresh air, the talk he did on this he compared the topic of SOA vs OO to sexuality and needless to say the outcome was very funny. SOA is based on OO “and if your feeling curious about experimenting with SOA there are places you can go in almost every large city to do this”

A very clever man and a very funny man. So far and I have a feeling this will be the highlight of TechEd for me.

Well Yesterday was the day of the big KeyNote speech a lot of big screens and music etc. It was interesting as its the first of its kind that I’d attended. They used it to launch the “Express” version of VisualStudio (well little bits of it). This is essentially ASP2.0 and Vis2005 broken down into bits for the Hobbyist developer. Plus a free version of SQL2005 (essentially replacing MSDE, considering it writes to a MDB file why dont they just call it JET )

First Session of the day was the Building occasionally connected applications. This was presented by Rocky so a good speaker, although I later heard he wasnt booked for this and its someone elses session, well it was pretty seamless if it was. Building on the Smart Client App Block her went through th evarious scenarios that presented the disconnected problem and detailed how the App Block dealt with them. This is the hardest of the App Blocks I looked at it, because it builds on top of so many of the others. I downloaded FotoVision, wonder why they didnt us the AppBlock ?? Cos its too damn hard!!!

Next was what I thought was going to be about VS2005 and Yukon, WRONG, they used this session to introduce further the Express editions, now I did glean some useful info from this sessnio about whats coming, the XDS’s can now be designed with a built in adaptor which you can add methods to to essentially create DataObjects in the XSD designer, no more splitting out the XSD and the Provider code into seperate classes, wonder what happens if you XML serialize this object ??? But this session mainly annoyed me, not becuase of the content but becuase I feel that MS have wasted valuable time in getting these products to market instead of concentrating on VS2005 and Yukon, for the Hobbyist. Sorry but Hobbyists don’t pay the bills its the people here, if people want to learn this stuff do it the hard way the rest of us had to what makes you so special ?

C# best practices. This was split into a lot of “Whats wrong with this code” sections its was an enjoyable session despite the very few questions I got right, its hard to spot these things as so much of it you could put down to style, which is what I did I thought I would write that code like this, strangely enough the way I would write it was the correct way, but I didnt know why in some cases. Others I did I just nailed the IDispose section but then I harped on about it so much I should do.

Lastly Don Box but I gotta go and he deserves his own section.

Found this nugget in the .net247 with a link to the MS site, google didnt list it

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpguide/html/cpconrowstates.asp

In a nutshell :

switch(m_objDataTable.Rows[i].RowState)
{
case DataRowState.Deleted:
this.SettingsManager.RemoveAdminSetting(m_objDataTable.Rows[i][”UserId”,DataRowVersion.Original].ToString());
break;
case DataRowState.Added:
strKey=m_objDataTable.Rows[i][”UserId”].ToString();
strVal=m_objDataTable.Rows[i][”UserName”].ToString();
this.SettingsManager.SetAdminSetting(strKey, strVal);
break;
}

Just found this
