Hi just about to get the dev team to start looking at the next version of a CRM type SOA based application and the thorny issue of Application Front End came up.
Currently the application is a composite application using
Web Forms (.net2)
Sharepoint 2003
InfoPath *
BizTalk
*Not FormsServer though - was before FormServer as we hack the ProgID in HTTP to launch a server based XSD for InfoPath and punch data into that on load.
We are looking at moving to MVC or MVVM model as we have web services and a database to interact with and we can see the move to that architecture to be a good one with 3.5 and Linq (although we have keyTables for managing one to many relationships that dont appear to work that well with LinqToSQL or EF... but i digress)
So we are at a point of looking at what would be good for the contact centre taking in these points
We must have a web server version for deployment (?) XBAP may diminsh this
Visulisation v Speed (WPF/SilverLight v WebForms and Grids)
So was wondering if anyone else faced this dilemma, hints tips and which would you choose based on your experience?
EDIT
Thanks for the links to Prism and the EP Site - already been looking at that - was hopeing for some real life expereinces...
xbap(can deploy on webserver) or wpf
patterns & practices: Composite WPF and Silverlight
Prism
Go for Xceed WPF Grid (xbap)

I am developing small institute management system as an academic project in my college.
I am going to develop the project in silverlight 4 or 5. In this project I want to provide attendance facility; i.e students will able to log in application from their respective machine which will be connected to LAN. There will be no internet connection available.
Can I develop this application which will not required internet connection once it is installed but can still accessible to different machine which are connected in a network over a LAN
1.How can I achive this?
2. should I use silverlight out of browser app or simple silverlight app
3. Is there any way to achive this using WPF?
After some research I found out the concept called Intranet which should solve my problem of sharing of source code and database.
About what technology should be used:
its better to develop this application in Silverlight as it is nothing but a subset of WPF.
Even better to develop the app in both technology to start with as I can use same XAML for both technology with few or no changes at all.
Connecting to database will be simpler in WPF than in Silverlight, as the later does not connect to the database directly and needs a service to achieve this. This service can be written using WCF or Ria service even in a php.
#Ash,
Silverlight can be desktop oriented, same as WPF. Caveat in some respects is that Silverlight is simplified to utilize Web Services communication, just like Adobe Flash is.
WPF is more oriented to non-Internat (ie Intranet/LAN) connections but pretty much utilizes the same .Net framework as Silverlight.
Although Silverlight is more platform independent than WPF, they operate the same.
You can take a Silverlight application and transition it to WPF with little to no changes (pending on the complexity of your application) to the code-base.
One benefit for WPF over Silverlight is the ability to utilize Click-Once deployment and Version control. Although you can implement a Click-Once styled Silverlight deployment it doesnt work the same as the majority of the Click-Once deployment models out there for the Desktop applications.
I hope this helps you.
Our client has a Desktop application (VBA and Access) that they are using for the past 10 years and it is buggy and they want to upgrade it. I want to use the latest MS technologies and plan to make this a web application using .NET 4.0, C#, SQL server and MVC running on the Intranet.
Since the application has many visual components (about 10 different tabs on top and each tab has atleast 10 different controls on it), I was wondering what is the best way to implement the UI layer a .NET web application. The 2 candidates are Silverlight and Telerik controls (we have license for this).
Some issues to consider :
Silverlight Plug-in : Since this new application will only be used internally on the intranet, I dont think installing a Silverlight plug-in will be an issue. Also, since its on the intranet, hopefully download speed should not be an issue for SL apps.
Telerik-MVC : It is really rich in functionality, however, I played around with it (.NET version not MVC) using some of the controls and if there is anything out of the recommended way to use a control, its a pain to get it working.
Skill-set : Do I want to learn how to use a tool (Telerik) or would I be better off learing a technology (Silverlight) in terms of future projects.
I would like to hear any feedback/ issues to help me decide which way to go.
If you are replacing a desktop application then going with Silverlight may be the best approach.
With Silverlight you are writing an application that happens to be delivered across the internet (well intranet in this case). This can be as stateful as you need to be. You have good access (no pun intended) to the database via the WCF RIA Services.
There's also the Prism MVVM model you can develop on top of.
However, I'd double check with the client as to what they are expecting.
Telerik also do a set of Silverlight controls.
If the project time permits, go for Silverlight. Also, if needed, it's possible to create a desktop version (WPF) out of the Silverlight project.
Issues with Telerik control set(or any control set), if you need a control that doesn't exist in the current set, you'll have to either buy from Telerik, or create your own. In the latter case, the whole UI aesthetics might break because it's not easy to create a control matches the tool set.
I'm in the early planning stages of an internal application and I'm considering ASP.NET MVC and Silverlight 4 as my possible platforms.
The Environment
We're a Microsoft shop and we're in the process of migrating desktops to Win7 (from XP) and servers to W2k8, I'll be able to get Silverlight 4 installed as part of our baseline Win7 build
The Application
Provide a dashboard to monitor system status
Monitoring third party connections
Monitoring database tables for particular events
Monitoring SQL Server Log Shipping
...
Provide portal like access to system tasks to end users
Bulk updates to databse rows
Running SSRS Reports
Re-running automated tasks that have failed
...
The Team
We're a small team of 2 and neither of us have production exeprience in Silverlight or ASP.NET MVC so we'll be learning whichever we go for.
What would you pick and why?
The answer really depends on your experience. If you are an experienced web developer and have a lot of practice with ASP.NET then use that for sure. If your background is WPF and WinForms then use Silverlight.
My experience is that the ramp up time to use Silverlight for an ASP.NET developer is significantly longer than it is for a straight .NET application developer. The ASP.NET developer has to unlearn a great deal before they begin because the development paradigm for Silverlight is more akin to app development.
The other alternative is to use both. ASP.NET for the navigation, authentication, general layout and Silverlight for the data realisation (graphs etc).
I would pick ASP.NET MVC. I have experience in both Silverlight and ASP.NET MVC and Silverlight undoubtedly has a steeper learning curve. While it will definitely enable you to develop rich user interfaces (it enables amazing composition) it may be overkill for an internal application.
ASP.NET MVC on the other hand will enable you to do what you are aiming to achieve but I believe (due to the learning curve) you'll be able to do so MUCH more quickly. It is also much easier in my experience to enable dependency injection and write unit tests for ASP.NET MVC than it is for silverlight which may or may not be a consideration..
Silverlight. I think ASP.NET MVC more for public websites, whereas internal applications - Webforms or Silverlight in your case.
Silverlight - Desktop > Web for applications (not for simple data presentations though) whenever possible. The bad news is that desktop is not always possible. The good news is that it is possible for you. You can even use the out of browser features which is even cooler.
Use Silverlight with the MVVM pattern.
We are planning to move to Silverlight 3 for application development because we want to take advantage of more flexible UIs and easier deployment. We have previously used Winforms with ADO.Net and SQL Server for data driven applications.
I've briefly looked at some of the options for data access with silverlight such as Entity Framework and Linq to SQL etc. But due to the pace of Silverlight development by Microsoft I do not know which method is the 'correct' method, and feel slightly overwhelmed by the options.
Can you suggest the best method for data access that I should pursue further reading on? Which methods should be avoided or are obselete?
If possible point me in the direction of a good comparison which I can't seem to find.
The technology that best suits you would be WCF RIA Services around Entity Framework.
Why Silverlight 3? VS2010 + Silverlight 4 is a much more mature platform for this type of Line-of-Business application.
That said, the biggest leap facing you is going from WinForms to Xaml based Silverlight UI.
With the new Silverlight 3.0 feature that allows the components to be hosted outside of the browser, our company is looking for details on the differences between this new feature and WPF Windows applications (since Silverlight is partly a subset of WPF).
Is there a good resource that lists the differences between Silverlight 3 outside of the browser and WPF applications? Areas like permissions, functionality, etc.
If there is no web resources, what are some of the key differences?
Silverlight OOB applications have the exact same capabilities as an in-browser Silverlight application, except they lose their ability to communicate with the DOM (via the System.Windows.Browser API).
Here is a brief list of some common things that you don't have access to with Silverlight that you might be planning on using in a WPF application:
Client File System
Client Windows registry
Client Event Log
Client OLEDB
Client SQL Client
This may seem like a long list but it should look fairly familiar to the no-can-do list for any web application platform (a la ASP.NET, JSP, PHP)
Jaime Rodriguez has a very good post covering the key differences and features of both Silverlight and WPF: Here. It's very high level and meant to differentiate between features that a WPF and Silverlight Out-of-Browser application bring to the table.
markti is correct.
