I am beginner for .net 3.5, have to work on app where I need to build desktop version as well as web version for selected modules like reporting. I think WCF will help me out to create a base from where I could call functions in both(desktop as well as web )
Let me know the any available source code sample projects to go through. It would be good if those are following any design pattern like MVC.
Here is a good place to start with WCF
and Here is a good start with WPF.
Have Fun.
You can take a look at the DinnerNow.net sample application. There's quite a bit that goes into setting it up but I think if you're ready to tackle both technologies at once it'll help a great deal.

Please bear with me if this is a silly question. But thought of getting an idea.
We have a very sophisticated Selenium Webdriver-Java framework. But now some parts of our application is being implemented in AngularJS. We would like to use protractor for test automation. But we have some API in the existing framework which we would like to reuse. Is there a possibility to do so or do we need to re-write all the existing API in protractor?
Thanks
Not probably the answer you are looking for. But, this can give you some hope.
Unfortunately there is no protractor java port at this moment. I use Selenium C# and my project started using some Angular recently. And, fortunately, there is a Protractor-net project done by some great people to accomplish same thing you are struggling with. I must say, if your project is big enough to leverage some time to write a java port for protractor you can follow this project easily. It's not that extensive. I am personally using it and started writing about this on my blog
Some one is trying to develop jProtractor - An angular/protractor implementation for Java Selenium API. https://github.com/caarlos0/jProtractor
This is still under development(not in a position to use yet), but this could be the right tool for people who are in similar situation as me.
Currently as my job profile i am more working on asp .net application but i also wanted to have my hands on silverlight application. so, i just decided to build one silverlight 4 application in my spare time and on weekends.
We are having a team of around 4 people. We also tried for commercial application but as we can only develop it in our available time we can not commit on timeline as well as we people are new to SL, so first we need to learn concept and implement it. (Though we know the concept of binding, commanding,templates etc.)
Now i just thought to work on project like creating a social networking site in SL 4
having facilities like forum, blogs, calander, task, dashboard etc.
We want to use features like .Net RIA Service, Entity Framework, MVVM pattern, SL 4.
Objective here is to learn new concepts as well as to get some good project experince in silverlight.
Now,
what you people suggest is it a good idea ?
If yes then the project selected is correct or you suggest some other project ?
Any pattern or technology related suggestions ?
This is quite a vague set of questions but I'll attempt to give my 2 pennies worth of advice.
As a learning project this is as good an idea as any to get going with. As a commercial idea it probably isn't such a good one due to there not being any niche in your product. It has all already been done, and been done successfully by the likes of Facebook and Twitter. Developing any kind of social media site is incredibly difficult as the market is already fairly saturated. As I said though, as a learning project it's quite nice as you can just borrow concepts and ideas from other sites and you can concentrate on you main goals of gaining knowledge in the various technologies.
Whatever you decide to do I'd say split the project up into much smaller components rather than having the end goal in sight. Try to take more of an agile approach by setting yourself 2-3 week targets. It should help keep the momentum going. My experience is that learning projects tend to die a death as people get bored of the concept and lose motivation to do it. By keeping the tasks small you get to see small results often. This should help keep you motivated as you move from requirement to requirement.
Personally I think setting up personal projects and goals like this are a great way of learning new technologies - good for you!! :-)
From a tooling perspective it sounds like SL4 is an ideal route to follow. This is highly likely to be released in early 2010 and has some awesome new features compared to SL3. Would also recommend using VS2010 and WCF RIA Service too.
From a code sharing POV have you considered hosting your project on Codeplex? This will give you a hosted TFS server to manage your source code in a distributed way. This is bound to save you some big bucks.
As far as document management is concerned Google Docs are certainly worth a look (as is Google Sites as a really easy to set up (albeit simple) project management portal).
Finally, I can't recommend learning SketchFlow highly enough. As a prototyping tool for silverlight it is really, really cool. Take a look at the PDC video for a great kick start on this.
Good luck :-)
Ext JS is a nice framework for web UI, but I found that building and putting stuff together takes a long time and painfully slow.
This might be a general problem when working with JavaScript, but does anybody have any way to speed things up?
What can I use? Better IDE with good JavaScript suppport? GUI designers? Code generators?
I need some way to speed up common things like building grids and forms but yet let me do complex things like creating custom components easily.
I'm using ASP.NET MVC. Coolite seems nice at first, but I feel that I'll be having trouble when creating any custom components later on.
There's always Ext GWT, which lets you use Eclipse tooling (and all of the advantages that gives you, such as refactoring, swift code navigation, etc.) to create your Ext/JavaScript app.
When you download the ExtJs library, you find lot of sample applications for common requirements like Grid panel, forms, form elements etc.
Regarding IDEs, you dont find mature productive tools, but check the below link and wish it could be of help to you
http://www.extjs.com/blog/2008/02/01/ides-plugins-and-tools-for-ext-js-20/
But if you really wish to develop custom components, you need to get through knowledge,start approaching with ExtJs-provided sample apps.
If you want to get faster at anything, practice it until you fully understand how it works and how to make it do what you want. If you are just starting out, why would expect to be able to work as quickly as you do when you are working on something that you are very familiar with?
Things I use to make ExtJS less painful
Chrome, for it's developer tools, or Firefox with Firebug.
snipMate: snippets for Vim, so I can quickly produce boiler plate code for classes.
JSLint as a command line tool. Especially good for detecting rogue commas.
Sencha forums.
ExtJS IRC chat (Server: irc.freenode.net Room: #extjs).
API documentation.
Sencha and Saki's ExtJS examples.
Beer.
ExtJS is building a designer right know so you can look forward it, the only problem I think is not gonna be free.
you can see a video demo there, in term of release date I think this is due to the first quarter of this year.
I say learn the framework. But to develop apps, I use IntelliJ IDEA, which has partial code completion, etc. It costs money though.
Once you have some practice and understanding of how ExtJS works, you'll get faster at it. By using the examples for reference, and building up my application in small pieces, I've gotten much better (and faster) at developing stuff with ExtJS. A great way to get started is to find an example (or two) that kind of do what you need, and modify (or combine) them to see how they work together.
I've been asked to do some work on an existing Silverlight project, mainly extending it a bit and doing bug fixes as needed. But there are a couple of ASP.Net pages too and a WCF service to deal with too. My background is desktop development with .Net so I think this is a good opportunity to start getting more involved in Web development.
So I'm trying to figure out what background knowledge I need for a project like this. Clearly I need to get familiar with Silverlight, but I'm not sure what other Web technologies, etc I need to ramp up on for this project. Obviously I would like to know as much as possible but in reality with limited time and resources I really need to focus on what I important in the near term for this project. Then expand my knowledge as things arise.
The things I'm thinking that are important in the immediate future are:
The basics of Web Development (I'm thinking this might be the most important\fundamental area to build a good foundation)
But what are consided the basics?
What is technology\language independent?
What is important for Silverlight?
The basics of ASP.Net (since there is some ASP.Net code)
What are the basics? ASP.net seems so huge, I have a 1000+ pg book here which seems daunting.
If you focus on Silverlight is knowing ASP.Net important, or is ASP.Net something I will continually run into?
How does ASP.Net MVC fit into the overall development picture and especially as related to Silverlight?
The basics of WCF
As compared what?
Any suggestions\comments on the list above?
What other topics\technologies will I run into if I continue doing Web development?
Note: Beyond this project I would focus on the Microsoft stack.
Generally speaking the amount of knowledge of ASP.Net you need to do Silverlight development is very very low.
Silverlight applications are hosted in a browser, usually via the <object> tag. This can sit on an asp.net page or a html page. The Silverlight template creates that for you, so you can forget its there and just get on with the Silverlight app.
Of course if you are integrating into an ASP.net environment (for example, islands of Silverlight sprinkled through an ASP.net site) then thats another thing. There are ways to get Silverlight talking to the HTML dom via the HTML Bridge but its not necessary. Really depends on what you are developing and integrating with. (new site vs existing)
I avoided ASP.net for as much as i could as the richness compared to desktop (WPF) just wasnt there. Silverlight changed all that. Its a Rich world on the web now!
Best place to start learning Silverlight is www.silverlight.net on the getting started part of the site. great Quickstarts and tutorials there.
Good luck
Only cursory knowledge of traditional web technologies (css, html, js, etc.) are necessary for silverlight development. As a consequence, you also don't need to understand the many cross-browser dependencies as well.
Here is my list of things that you must get a really good understanding of to be proficient at Silverlight development:
Understanding WCF (the Silverlight-supported parts) is essential. It can be a configration nightmare, but once working it is pretty stable/ reliable
You need to understand serialization used by WCF and how to debug the mysterious 404 errors. Get good at Fiddler and/or Firebug.
You must understand multi-threaded applications and how do debug them. Silverlight makes extensive use of threading to not block the UI thread. This creates numerous opportunities for race conditions that create what appear to be "magical" results. That said, it is incredibly powerful and IMHO one of the dominant reasons to use Silverlight.
What you learn about serialization and WCF will ultimately help you cache some data in IsolatedStorage. Learn about IsoStorage, it will reduce our bandwidth requirements and cost and improve your user experience
Learn about Linq - again this is one of the most powerful features of Silverlight. Combined with a smart client-side caching strategy you can offload lots of processing to the client.
Figure out how you going to support printing. SL3 does not at all and you will need a server side component. SL4 beta does, but it is not go live
Understand the Silverlight Roadmap as much as possible and plan out your roadmap to match/ sync with it as best as possible. I first built a SL2 app and I spent a lot of time building things by hand that were ultimately released in SL3. As it is getting more mature, there is less of this.
Download the Silverlight Toolkit and use it. But more importantly examine the source code, the structures, its build process. There is not better real world place to look for inspiration & best practices.
Good luck.
I'm getting ready to develop my first Silverlight app. It is going to be primarily used by my church for data input but also will need to generate at least one report, ideally in Excel but XML/XSLT is not outside the realm...
It will be Internet facing and will talk to a SQL Server 2008 db for which I will be creating a web service hosted at the ISP (db is also hosted at the ISP). The clients will be a mix of Windows and Mac.
My question specifically relates to the interface architecture. I know MVVM is big for this right now and I'm comfortable with that. I want to get this up fairly quickly (ie- next 3-4 weeks). I've also seen mention of Prism (Composite Application Guidance) and Caliburn. What are anyone's thoughts on these two? The initial version of the app is not going to be huge so I don't imagine it would be overly difficult to refactor a framework into it at a later date.
You are right, if it's your first development on SL, adding the complexity of MVVM won't help you much.
I think a good approach could be to go for something simple (e.g.: the good old Document/View could be just a good start http://msdn.microsoft.com/en-us/library/4x1xy43a(VS.80).aspx, or just breaking in standard layers, UI / BS / DL).
After that development you will have learnt a lot of good stuff, and then you will be able to throw your app and start new bigger challenges using more advanced architectures (about MVVM, a very good web cast: http://blog.lab49.com/archives/2650 it's WPF based most of the concepts can be ported to SL).
Good luck and enjoy for SL development.
Cheers
Braulio
Start with something you are very comfortable with especially if you need to get this up quickly. Follow good coding standards and should not be a problem to refactor later into other frameworks if you get a bigger team.
This is a useful pdf.
I haven't read it in detail yet myself, but this article looks rather useful:
