Difference between Web Site project and (NEW) Web application project?

Hi there,

i have been reading about the new Web application project (addon) for Visual Studio 2005, all sounds really nice but i just can't put my finger on it...

Whats the differences really? And why is  one better than the other?

I also read about the Visual studio 2005 Web deployment projects, which from what i can gather allows us to deploy our code like back in 2003 i..e. with a BIN directory  and dll which is the compiled code behind stuff..

are these in anyway linked together?

Thanks in advacne for any info..

Best rregards

Thanks Mikhail! Thats just what i was looking for...

Do you know once i have published a file... which files i can update without have to REBUILT/REPUBLISH a site,...

For example i know i can just copy web.config up .. that works..

But i thought also default.aspx (not codebehind) could be edited (html) and uploaded?? I just tried it and when i did i got an error msg saying it "couldn't find default.aspx.cs" which i thought was compiled into some dll's.

P.s. this is using the Normal web site schemea of visual basic 2005 and not the new Web depolyment project (well not yet anyway) :-)

Thanks again

ahhh i just discovered something...

My default.aspx file (html not codebehind) in my visual studio project and the code behind in my PUBLISHED site which i put temporary to a directory on my local c drive are a little different..


<%@ page language="C#" masterpagefile="~/MasterPage.master" autoeventwireup="true" inherits="_Default, App_Web_45fljkht" title="Untitled Page" %>

the above adds App_web_45fljkht" to it!

Does anyone know the best way around this...

So i presume if i do edit my published default.aspx file on my local c and then copy to server it would still work......

But of course i am editing the files in my VS 2005 which are in a non published state...



4/6/2006 1:19:02 PM
One idea i had was to re-edit the file is vs 2005... republish..... but the problem with this is that when i do sure enough the default.aspx file is updated but the naming of the dll assemblies seeem to be different everytime so if i reupload default.aspx then i have to re-upload my bin folder too..

Or this is how it appears to me anyway..

Anyway throw a little light on the subject?

Are you using the Web Site project model with Web Deployment Projects?  If so which option are you using for output assembly? 

  1. Merge all outputs into a single assembly
  2. Merge each individual folder into it's own assembly
  3. Merge all pages and control ouputs into a single assembly
  4. Create a seperate assembly for each page and control output

If you're planning on deploying the code behind assembly and then updating the .aspx files on a regular basis you might want to consider using the new Web Application Projects.  This model is closer to the VS03 model and easily allows you to deploy the code behind assembly and pages seperately.  For example it's publish feature is smart enough to only push the pages and controls if that's all that's changed with out pushing up the code behind assembly.

Hope this helps, Brad.

now i am using the old web site project model with vs 2005 ... but NOT with web deployment project.

My idea was to really truly understand the old way first before moving onto the new one....


4/6/2006 4:11:53 PM

Got it.  When you publish using the VS05 Web Site projects be sure to check the "Use fixed naming and single page assemblies".  This should prevent the dll name from changing. 

Hope this helps, Brad.

I just built my first Web site project and published it and noticed that I have a dll for each page instead of one.

Is this how VS2005 works?

In VS2003 it would only create one dll that had to be deployed for the WebUi Layer.  I am just trying to gain understanding.

That is correct.  In VS 05 we rely on the ASP.NET server side dynamic compilation.  During publish we run the ASP.NET pre-compiler aspnet_compiler.exe which produces multiple assemblies.  We refer to this as the Web Site project model.  This is substantially different that VS03.

The primary advantage of the Web Site project model is for source level deployments or for precompiled sites where you want to service individual pages w/o rebuilding the entire site.

We've also provided a web download called Web Application Projects that provides a compilation model comparable to VS03.  You can learn more here http://msdn.microsoft.com/asp.net/reference/infrastructure/wap/default.aspx

Here is a good description of the differences:

How do I go about setting the output assembly to a single dll, I'm using vs2005 with a website project.

Thanks, and great I was unaware we could set this option.

Use a Web Deployment Project in conjunction with your Web Site project.


Hope this helps,

Problem when deploying Web Application project over VS2005 Web Site project
Hi,  we ran into this issue yesterday evening when we were trying to deploy new code on production box. It was running previous version of our app that was VS 2005 Web Site project, but the new version was migrated into Web App project.

Converting a Web Site Project to a Web Application Project ?

Converting a Web Application Project to a Web Site Project
I converted a VS 2003 web application to VS 2005 using the Web Application Project model.  Is it possible to convert this to a Web Site Project once it is upgraded to VS 2005? We don't have any automated tools to convert from VS2005 WAP to Websites.  If you really prefer to use the website model, I would recommend converting directly from VS2003 to Websites.  To do that you can open the VS2003 app using the "Open Website" command.Omar KhanVisual Web Developer Team I thought you were going to say that.  I have spent quite a bit of time getting rid of most of the warnin...

Integrate/combine web application projects with web site project

How convert VS2005 site web to new Web Application Project
We found out about the new Web Application Project tool a few days too late. Our VS 2003 web app has now been moved to the default VS2005 model. Now that we know about the new Project model add-in, we'd love to convert to that. Our biggest problem with the standard VS2005 model is that non-GACed references aren't stored anywhere...it just looks in the bin. This is a pain for our build/deployment process (no more Copy Local). We can GAC a lot of assemblies (even though we don't want to), but some of them are third-party unsigned assemblies or COM interop assemblies, so they have to be in th...

Web application project or Web site project which is "better"?
Hi,We are a bit confused as to which web project type is best to use.Currently we have a number of large projects in the old style with .vbproj files. These have been upgraded to VS2008 web application projects. Compilation seems slower of upgraded projects than created from scratch web site projects. I do get the impression MS is pushing the new style format for future releases.What are the advantages/disadvantages of the new web site project?Where do references get stored in the new style project?Where do the control declarations get hidden in partial classes?Thanks, Alex ...
