How do you update an ASP.NET web application? - asp.net

Simple question. If you have a compiled and published ASP.NET web application running on a server and you need to update, say, a line in one of the codebehind files. Do you shut down the entire site, republish, then load the site back up? Or do you publish straight to your live site with users still using it?

For myself, place an app.offline app_offline.htm file into the site, then overwrite the entire website with the latest published build.
there are a few options when building a site -> one dll for the site or one per page. if u just updated one line in a code behind, and you have chosen the build option for one per page, then you can just copy/paste that new page dll.
i don't like that method personally. I find it simple to app_offline.htm the site.

If it is a single file and a simple site that uses that app_code folder to store the code behinds, I simply xcopy up the new files. If I use http expiration headers I may need to do some better scheduling to make sure things like javascript files and css sheets match the rest of the site that was updated.

For emergency patches:
If its just a codebehind file, I copy the entire /bin/ out and replace all DLL's (mostly out of habit)
If its an aspx, I just copy the aspx.
For actual deployments, I have an automated system that checks out the code from source control, builds a clean release build, takes the site offline, and then robocopies it out to the deployment target. Its a one click process (Thanks CruiseControl!).

Publishing ASP.NET files to hosting server and back to local machine.Step by step procedures

I am very new with ASP.NET. I need help understanding the basic procedures of how a developer publishes their site to their hosting server, and then once its compiled and published, how does another developer (someone who does not have the original files), edit some of the code behind files.
For example, Developer A creates a site, uploads it to the server and it works great. We hire a new remote developer (Developer B) and he needs to work on a .cs file, does he need to get a copy of the entire site, to his local machine? if so, does he need to reverse the compiling process to get thos .cs files back?
I am a PHP developer, and since theres no compiling needed, I dont worry about .dlls nor about compiling at all. This would truly help me understand ASP.NET with the hopes that it can also help others like me.
Please help. Thank you in advance.
You do not need a copy of the entire site.
But you need the basic struct of an asp.net site, and what resource you may need to run this individual page.
The minimal basic struct of an asp.net site is this two directories (and the content of them - if any)
App_Code
Bin
together with the web.config that is probably needs some changes to run to the remote developer.
Now some simple logic.
If a page have css, javascript and other files you need them too
If a page need connection to some database, you need that too
In the bin directory you may only give the dlls/libraries that this individual page use (if any)
If the page have links to other pages, or post to other pages, or need ajax call from other pages you need them too.
If some one change some functions on the dll files, you must give the update to the remote developer so he can adapt his code.
After the update he can upload the aspx + cs file on the server.

Updating .aspx pages

I've inherited an ASP.NET project that uses a single Default.aspx file in the public_html root to do most of the work.
The changes I'm making are minor, but I can't seem to get them to stick. If I edit the Default.aspx file, the server will still serve the old version. Creating a new .aspx file will initially compile it and run it, but then it's stuck in its "original request" form.
I thought .aspx files were subject to "dynamic recompilation" if they were changed, but this isn't triggered in my case. I've tried updating the Web.config file but is has no effect.
I'm not using Visual Studio for this, yet. I'd like to be able to just edit and update the files, if possible (the changes are very minor and I don't have ready access to a Windows machine). The only access I have to the server is through FTP.
Seems the issue was with my host, who aggressively cache stuff. I have to do a "restart" from inside their control panel to have the changes reflected.
The host is Loopia.se, in case anyone else is using them. Use "Omstart av ASP.NET-applikationer" from inside the Customer Zone to restart things.
(Yes, I do feel kind of silly now)
If the site has previously been 'published' in visual studio as pre-compiled and not-updatable, then changing the aspx files will result in no change:
http://msdn.microsoft.com/en-us/library/1y1404zt(v=vs.80).aspx
In this case everything will have been pre-compiled into DLL's, and the aspx pages are just there as hooks for the .net runtime.

Visual Studio 2010 - Partially Publish Web Site?

I just completed a website that is image heavy and I'm publishing the site to an FTP server. The publish time takes ~5 minutes. Is there a way for me to configure which file types get published? I'd like to push out changes only if the file extention is: (.config, .aspx, .cs, .asmx, .js, .html, .css, .master).
Is this possible?
No, the publish process publishes the whole website.
Publish it on your local computer first and then use an FTP tool (Filezilla, CoreFTP...) to selectively upload your files to the server.
Unfortunately No, it is not possible. Publish operation is either-all-or-none operation.
Even though, I sometimes only copy the DLL assembly (from bin directory to IIS website folder) if the change is only in the code-behind files and the markup/images/other-content have no changes.
you can set the Build Action for whatever you don't want published to None
These won't get copied to the deployment directory
I have just confirmed that it works (I tested on a MVC3 site)
so you'll have to change the setting for each file you want to exclude but you can change the setting of multiple at one time and folders can't be excluded

Deploying a Pre Compiled Web Site Project

So I have a website project, which I precompile when I publish.
I have a question, when I need to make a small change to the deployed site, do I have to rebuild, re-publish and deploy the entire website structure again, or can I just copy the modified aspx page and the bin directory?
Please let me know!
Thanks guys!
It is going to depend on how you did the precompiling of the site.
According to MSDN, if you did a precompile for deployment, the process takes aspx files and processes any internal code in them, so you will need to recompile everything.
If you did a precompile for deployment and update, the aspx files are not taken into consideration, so provided all you did was some UI changes, you can push the updated aspx file up without issue.
You should be able to republish locally and then copy up the modified published pages and the bin folder.
You shouldn't need to upload everything.
If you pre-compile epending on the options you have chosen you may be able to edit the .aspx page i.e. HTML code, but not the code-behind..
If the .aspx pages become just placeholders i.e. they are empty inside except for a single comment, you cant.

Can you precompile and merge part of an ASP.NET website and then continue development?

A big part of the web site is precompiled and merged, since it's almost never going to change. The precompiled bits can be replaced in case of updates to the original. I want to continue development of new pages, but when I browse to a new page I get the following error:
The file '/Website/Test/Default.aspx'
has not been pre-compiled, and cannot
be requested.
Is there any way around this?
Edit:
If I remove the precompileApp.config file I get the contents of the marker files when I browse them:
This is a marker file generated by the precompilation tool, and should not be deleted!
Have you looked at the precompile with updatable UI option? This compiles all the source code and resources into a DLL but allows you to continue making changes to your .aspx pages after deployment.
Another option could be to precompile the website in place on the server instead of precompiling it then deploying it to the webserver.
Both options are addressed in this MSDN article:
