I am using Technologies .NET3.5,C#.net,Sqlserver2005,WCSFWe want to develop a project in wcsf, will it be good and easy??.What is wcsf just briefly. How to develop MVP Architecture.Mainly I gather some information on wcsf, and i got some knowledge but i want sample application or project to get knowledge to develop a project.i am not getting any sample application google, and proper meterial also not there, is it failed or succeeded. if develop project in that will iget any problems in development.
i want to develop an application in asp.net using 3 tier architecture .
i know that there are three layers
Data layerBusiness Layer
Data Access LayerBusiness Logic Layer Presentation Layer. I am confused between Data Access Layer and Business Logic Layer.
In data access layer we develop the property classes and main class function which returns datasets, datatables and data reader to Presentation layer.
what is the use of Business Logic Layer ? what actually we do in Business logic Layer ?? we can pass data directly from data access layer to presentation layer ?
i am going to develop a web based application with c# but i am very upset that how to design a good pattern how to code to let the program more efficient.
I'm starting to think about and develop an architecture for a big web application, and I wanted to get suggestions and/or recommendations on which technologies and/or frameworks to use.The application will be an Intranet-based web site using Windows authentication, running on IIS and using ASP.NET. It'll need to be structured as a main web application with sub-web applications. Essentially, the entire scope is a composite browser-based,Intranet application that is composed of discrete, functionally complete modules or sub-applications.
I am trying to develop a plugin architecture in .Net. The application will be a .Net application. There will be directories which holds the plug-ins. Each directory will represent a plugin. Each plugin directory will also contain all the dependency dlls as well. The plugins need to be stored in separate AppDomain as the plugins may use the same assemblies, but different versions. As it iterates through the foreach loop in Init(), I get a System.IO.FileNotFoundException : Could not load file or assembly '[Assembly Name], Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified.in _apDomain.Load() for assemblies that are not in the main project.
I am looking details on the internal working of asp.net architecture. The topics need to include the following:
Asp.Net Thread/Application Pools HttpRuntime HttpApplication - When and how it is set up How HttpContext is set up How objects can passed along the pipeline using HttpContext.Current.Items Why does modification of static variables requires locks in ASP.NET (advanced)IIS 7 Integration Mode
i want to create a centralised business or Service authendication architecture in .net. for example, we have a clients like c1, c2, c3, c4, ... etc. everybody logins seperatly as well as grouply. ie, if client "C1" logins [with login authentication] he can access c2 , c3, c4 also without login authendication. So its like a google. if we enters gmail account, we can access orkut, picasa like that.. i need the cetralised architecture.
And, client "c1" seperately asks seperately how will be the authendication architecture.
so give me the single solution for both these two scenarios. how will be the architecture for these two and how is the Data Base (Login) Structure.
recently i've studied on ADO.NET's Entity Model Framework and say 'wow' as ORM is one of the fevourite pattern i practice..but suddenly i've come to an ambiguous situation when i'm going to start. i usually follow the following 3-tier architecture..
1. UI Layer 2. BLL - business logic layer 3. DAL - Data Access Layer a. DTO / DAO b. Gateway (contains the sql query/stored procedure and connection with DB)
now when i'm going to use the Entity Model Design,where the DBML/ .edmx File should be placed? Because many a times i'm using the DBML file as DTO because of the mapped objects.. in the same time, sometimes DBML ( .edmx file in .NET 4.0) contains CRUD methods and stored procedured method as well as methods with different selection operations,- which should be in Gateway. so where the .edmx file should be placed !?!! IN DTO namespace !? or in Gateway namespace!
moreover sometimes there is no need for the BLL which breaks the rules of inter-layer-communication (UI > BLL > DAL.Gateway)! what makes me confuse is, what should be the ideal n-tier architecture when i'll use the ADO.NET Entity Model Design Framework
I am working on 3 tier architecture: UI, BL, DAL. In my UI i have following code for Asynchronous page processing:
[Code]....
But I want a database fetch operation to be performed in this asyncronous method. And due to 3 tier arch. i am unable to do this in UI Layer. Can anyone guide me that how can I implement Asynchronous processing in 3 tier architecture? Note: If you are going to place EndAsyncWork1 in DAL then show that how can I return a value back to UI layer from this function.
I want to know that What are the factors if we use methods on each .cs page for connection and executing query on each aspx code behind page rather then using BAL .
How our application get affected in terms of performance and speed or other way?
when we put our website on server after publish/compile in general approach (using query in C# code behind) rathor than using stored procedures?
I have implemented the 3-tier architecture project; DAL, BAL, and presentation layer are three layers in it. I am going to implement the following scenario:
Presentation layer calls to a function in the BAL layer which returns 2 string variable, and in turn this function from BAL layer calls to a DAL layer function which also returns 2 string variable. How can I implement the above scenario?
I'm developing a n-tier architecture... I'm confused with handling exception in the layers... Is it a good practise to add a Exception Layer to the architecture.
I am a newbie to asp.net and work in a firm where the projects are quite small.
I was told by my manager that in a few weeks or so we would be getting a bigger project and I need to be well versed with Design Patterns and N tier arcihtecture.
I would really appreciate if someone could provide me some links and also drop me a few sentences on how this things are useful?
I am going to create the SAAS (Software as a service) Application. Can you please provide all the attributes that we have to consider in SAAS application (for example usability, pluggable architecture etc .. )
How architecture should be build for this project, provide sample architecture for SAAS application. This architecture should be easy to upload and upgrade or degrade the features. Error handling should be easy.
I am try to create architecture design for WCF service.
We have WCF service that we have to expose to third party so then can request with xml and get back xml response.
The wcf service should do the following:
- Accept the request call with xml
- Check xml against the schema
- Parse the xml
- Authenticate the incoming xml by username and password that will be in xml
- Send back the response
If anybody can let me know what kind of design I can use or is there any pattern available that I can take it and then extend it as per my requirement.
It's Possing to make a web site a web site to be extended using plugins?im planing to make a bugtracker using the webforms in aps.netbut icant find a tutorial about how to make it extendable
i know some thing about the MVP pattern... but when you want to develop a project(web project) based on the MVP pattern from where we need to start... i mean which component we need to start developing first ... Model or View or Presenter... what are the points that we need to keep in mind....
guide in typical 4 layered architecture (having User Interface, Custom Types, Business Logic, Data Access Layer) do we follow some design pattern ? I am not clear what pattern it is or what pattern it should be called.
am creating service oriented application , I am calling all my services through jquery but I am having a problem that I dont feel writing jquery calling scripts from the page and exposing the service names is something goood....like at least I shall have only one class that's calling , so...I am having some kind of problem to find the most suitable architecture about that
was giving a though on using ajax enabled wcf services as part of architecturegenerally wht im usingis UI-> BL-> data accessis it suggestable to use wcf services layer insteadof BLnd hv UI-> services-> data accessrelated to asp.netwould like to no pro's and con's of doing this thing.
I was tasked to create 3 tier web application. However, i browsed through many books & tutorials. The examples are doing it using Object data source which my lecturers claimed that it is not 3 tier at all. Shouldn't be dragging any data source into deisgn view. Any comprehensive examples for me to take reference from?
(1).MSDN say that we should not have the namespace where its name is same with class name but it does not exlpain why.Does anyone know why? The msdn page is http://msdn.microsoft.com/en-us/library/893ke618%28VS.71%29.aspx
(2). Business Logic Layer BLTable1 need to interact with Data Access Layer DaTable1 , so i put the code: imports MyCompany.MyProject.DA. DaTable1 inside BLTable1, so that i can have access to all the public shared method inside DaTable1 in BLTable1 for example : DaTable1.Save()
But problem arise when BLTable1 want to use the public shared method in BLTable2 .
I have put the code imports MyCompany.MyProject.BL. BLTable2 inside BLTable1,but i need to key in the class name twice only can access to the public shared method inside BLTable2 for example :BLTable2.BLTable2.Save.
I'm supposed to be designing solution architecture for an upcoming project (clearly the most advance I ever did and guaranteed to drive me nuts over the coming months). I'm trying not to let my knowledge shape the design, and rather create a solid, maintainable design and fill the gaps in my knowledge later.Was hoping to hear what others think and help me shape this.In a nutshell it will be an asp.net mvc application running on the azure platform (so I'll be using azure table services for data storage and blob services for file services).
Been nutting out Entity Framework 4 (don't know NHibernate at all) over the past few days and figured I'll use that in the data access layer (c# class library) to map my domain model (another c# class library) to the data storage (still no idea how azure storage work, but will get to that).My WCF skills are shaky, but I'm thinking of exposing data via services, though right now I cannot think of that being that useful....
Front End: XHTML, CSS, JavaScript (jQuery & jQueryTools), AJAXWeb Client: Asp.Net MVC 2Domain Model: C# Class library with POCO , interfaces and implementations (will be using Castle Windsor as IoC)Data Access Layer: Entity Framework mapping my domain model and data storageAzure Storage: ...
