How To Get Started Building C# And .NET Web Applications
Mar 12, 2011
I am planning to create a Customer Relationship Management (CRM) application. I have to use C# and Visual Studio 2008. What is the best approach to get started and what resources can I use to make this process easier?
I've been worked with web services so far, and I'm interested in expanding my services to console applications as well so I started digging up with WCF but I'm conserned that I won't be able to use the HttpContext collection that I've been used to do with web services one important thing which is to generate a random value from HttpContext.Current.Request.ServerVariables["ALL_HTTP"] that I need to reckon if it's the same or at least near what machine that is calling my service. How can I overcome this problem?
I need to know what machine is calling to count the number of attempts to login into my system for example. So must do it inside of the svc code otherwise if I let the client inform what ip address or what computer he is using, anyone could forge this argument and surpass by another machine. May be I'm approaching this matter wrongly. And I should count the number of attempts per state session, but how is it done?
where to create the BLL and DAL and all classes in it can we place them in the App_code folder as it ll convert them into DLL Files or do we have to create a new class library project for each...
is session state must get destroyed each time we are building our project in web applications? this is really annoying because i have to re-log and get to the page i'm currently working on each time i need to build my project...
Our corporate intranet is designed so that each web application is a child application in the primary application.. Everything has worked fine with Visual Studio 2008 and even in 2010 running the website locally works great, the output directory for the child apps is ..in and the ProjectName.dll copies to that directory.. When I do a publish however it does not and I have to manually copy the dll from the bin folder in the project folder to the parent bin folder, this isn't hard of course but more of a pain in the butt each time I need to publish something. I made sure the output directory is correct for both debug and release yet on publish is just copies it to the child bin and not the parent bin as needed.
I created a simple page using the code provided by this page (the first sample): [URL] But I can't seem to get it to work, I can redirect to the provider but when the provider redirects back to my page, I get error 500, "The request was rejected by the HTTP filter". I already checked ISAPI filters which I have none.
I'm taking my first stab as using AJAX. I'm starting with a simple example to update the time when a textbox changes. So I added the following at the top of my content page's placeholder:
[Code]....
And then, lower down, I added an updatepanel.
[Code]....
But nothing happens. I edit the textbox and tab out and nothing updates and nothing changes.Am I missing a web.config setting or something that I can't find reference to in all the articles I found? I'm using VS2010 and .NET 4.
Are there any good resources and sites related to developing with SharpSVN and normal SVN/VisSVN I've so far only come across a few samples that deal more with JIRA.
I'm new to ASP.net and used the on-line demo under the getting started section to try and build my first MVC app. [URL]. This is a great video and is just the kind of thing I need to help me learn as I hate reading though books! However I have gone through this tutorial 3 times now and I can't get it working. Well, I follow it step by step and get the following error. The only difference is that I am using Visual Studio 2010. Being new to this I need to become familiar with all the standard error messages but at the moment they are all foreign. This is my FriendsController.cs I'm not sure if I need to post the other files as I know the database is setup ok.
The error message is: Error 1 'HelloWorld.Models.FriendsDB' does not contain a definition for 'Friends' and no extension method 'Friends' accepting a first argument of type 'HelloWorld.Models.FriendsDB' could be found (are you missing a using directive or an assembly reference?)

I have very much experience of asp.net developement. But i have never dealt with https. In my one project i require 2/3 page with https. So please any one can explain me how i can start with https. Please explain me in detail about about developement cycle, and any other if there is any settings.
Today is my first day using ASP.NET MVC, and I'm finding it very intriguing. I only just started learning asp.net.
So basically I'm trying to call a procedure from an MSSQL database, and with it I need to send a paramater "PlaceID", which is an integer. This procedure basically just picks out a number of columns from different tables in the database. Here is the Linq to SQL code
The ultimate goal is to be able to retrieve all the information and return it as JSON with a function that will be available for a javascript.
I'm wondering what is the best way to proceed from here. I know I have to create a view, but I'm still unclear exactly on how I can call the procedure and make it store all the information. I could really use some help on this, some code examples would be excellent. I already wrote a C#.net function to convert a datatable to JSON using a stringbuilder, but I get the feeling there is a smarter way to do things.
I am trying to figure out how to get DotNetOpenAuth(http://www.dotnetopenauth.net/) working in my webforms app
I don't understand where to begin. I have an OpenIDSelector on my Login.aspx that lets you choose google or Yahoo. You can choose one, then a popup comes up, and lets you login. Once you login the program hangs because it is trying to do something with a database???
Can't I just use some control(like the OpenIDSelector) and get back that the user was authenticated, get their ClaimedID and handle the rest myself?
EDIT: Trying to get started with OpenID in Webforms? Go Here...
Thus far working with asp.net webforms was very easy .... But never implemented URL Routing in webforms... I know asp.net MVC Handles URL Routing pretty well... How to get started with URL Routing in an asp.net webform application? For EX: [URL] i want it to be like [URL] Any good article to start with URL Routing asp.net 3.5
I'm not really a developer but I have experience in PHP, Java and want to have a go at developing some really simple SharePoint web parts (for WSS 3.0, MOSS 2007 and in future 2010).I assume it requires knowledge of ASP.NET. Should I start learning C# or get stuck straight into web parts.
I have just been told to get looking into using SQL server reporting. Does anyone have any good links they would recommend? can this be used for reporting on ASP.NET sites?
I have developed for SharePoint and in those cases it is clear how workflow can (You have documents that needs approval and there are built in SharePoint workflows for this) But now I am doing standard ASP.NET web CRUD apps with WCF. I would like to find a way to get WF 4.0 invovled but I am not sure how to do it and never see any examples....
The default ASP.NET web server that launches from within Visual Studio (Casini) is a little buggy on my development machine, so I like to publish to a local IIS instance on my dev machine and look at the web application there. However, I'm not automatically in "Debug Mode" when I launch the application this way.
I know that VS 2010 has an "Attach to Process" debug feature, but I'm not sure exactly how to use it. What do I need to do to be able to debug a local IIS ASP.NET web application from within Visual Studio? Specifically:
What settings do I need to change in the configuration of my web application?
What "Package/Publish Settings" do I need to change?
Is there anything I need to change in IIS?
Is there anything special I need to do in the "Attach to Process" screen?
Background Information: I'm running Visual Studio 2010 on Windows XP SP3 with IIS 5.1 and .NET 4.0.
Additional Information:
I should add that I've tried attaching to aspnet_wp.exe, but when I go to a page that I know has a breakpoint in it, I get the following message when I hover over the "open circle" breakpoint:
The breakpoint will not currently be hit. No symbols have been loaded for this document.
I see to down load ASPAJAXExtSetup.msi (Microsoft ASP.NET 2.0 AJAX Extensions 1.0)
I am not an admin on my computer, i work in one of those places where it takes 1 week or more to get 1 thing installed.
Please help me find the exact items to install for vs2005 and the exact order. If i could do installs myself i would just keep trying till i got it, but if i take that approch i will be out of the job i started 2 wks for not getting anything done while i mess with this.
