I would like to update the web.config file by C# in windows container.
The following is a function of updating web.config in C#
private void UpdateWebConfigFile()
{
var configuration = System.Web.Configuration.WebConfigurationManager.OpenWebConfiguration("~");
var section = (System.Configuration.ConnectionStringsSection)configuration.GetSection("connectionStrings");
var defaultConnection = section.ConnectionStrings["DefaultConnection"].ConnectionString;
section.ConnectionStrings["DefaultConnection"].ConnectionString = Environment.ExpandEnvironmentVariables(defaultConnection);
configuration.Save();
}
but an error occurred in configuration.Save(); that I get the result as following
Server Error in '/' Application.

My question is How to update Web.config in the application of Windows Container?
Thank you!
Containers are by design intended to be immutable, and as such, the default user is set to a non-admin account which will not have permissions to modify the IIS directoy.
While you can modify the runtime user to be an admin, this would present another issue due to the way that IIS inside a container is montiored. Changing the web.config would cause IIS to reset the pool, which docker would treat as a process crash and stop the container.
Either you should modify the web.config as part of the container build, or you should use environment variables directly rather than trying to write them into the web.config when the container is running.

I created asp.net application. then I build that on visual studio and then I added web.config file and added following section in that web.config file
<remotingSetting baseRemoteAddress="http://localhost/application_name/{0}"/>
<securitySetting accessDeniedUrl="~/Default.aspx"/>
then I created a site as application_name in Default Website using IIS manager
Then I try to browse this application in IIS manager, I'm getting following configuration error.

I have created a website on visual studio and I have added an SQL database onto it. I am using DetailsView and GridView to display the data. It works perfectly before I published the website using GoDaddy. I am assuming there is some security issue I need to fix. Any suggestions or help would be great. Thank you.

Anyone know why this is happening? I can normally run asp.net 2.0 and above web-forms perfectly will on this server.
You get this error because you have place a web.config in a subdirectory and this contains sessions that should be there, except if you define a new application/pool asp.net in this subdirectory of your iis.
From you question, here is the path of your web.config, but this must be one directory up, or not exist at all, or remove the lines that can not be there.
C:\Inetpub\wwwroot\test_uploader\uploadify\web.config
I have developed a web service with the .asmx extension using C# and i want to deploy this into my VPS which has Windows Server 2003 with IIS 6.
Service is running with Framework 4.0 and it's installed in the VPS also. When I upload the precompiled version into the VPS it shows a runtime error
Server Error in '/' Application.
Runtime Error
Description: An application error
occurred on the server. The current
custom error settings for this
application prevent the details of the
application error from being viewed
remotely (for security reasons). It
could, however, be viewed by browsers
running on the local server machine.
Details: To enable the details of this
specific error message to be viewable
on remote machines, please create a
<customErrors> tag within a
"web.config" configuration file
located in the root directory of the
current web application. This
tag should then have
its "mode" attribute set to "Off".
<!-- Web.Config Configuration File -->
<configuration>
<system.web>
<customErrors mode="Off"/>
</system.web>
</configuration>
Notes: The current error page you are
seeing can be replaced by a custom
error page by modifying the
"defaultRedirect" attribute of the
application's <customErrors>
configuration tag to point to a custom
error page URL.
<!-- Web.Config Configuration File -->
<configuration>
<system.web>
<customErrors mode="RemoteOnly" defaultRedirect="mycustompage.htm"/>
</system.web>
can anyone help me on this?

this is the new error message after enabling debugging in the web.config
You should enable debugging to diagnose the problem.
Microsoft has a very detailed explanation on how to enable detailed debugging over here.
Server Error in '/' Application.
That error is too generic, check the output after you enabled debugging and post the results.
And don't forget to disable debugging after your site goes live.
Update:
Seems to be permission related:
http://forums.iis.net/p/1042369/1454379.aspx
The ASPNET user account needs permissions for the folder that contains your asmx service.
Update2:
You can give the ASPNET user permissions using the file system permission dialog:

Might look different on newer versions of Windows.
From my experience "Server Application Unavailable" means that you have got web sites that use different versions of .net in the same application pool.
the site that hosts your webservice needs to be in an app pool that only has .net 4.0 web sites. The application pool is configured on the Home Directory tab in the web site properties.
Looks to me like the application pool is trying to run two difference versions on .net.
Make a new application pool and call it something like .Net4 and then move the new site across to use this app pool and everything should work.
This error is shown by
Version Information: Microsoft .NET Framework Version:2.0.50727.3053; ASP.NET >Version:2.0.50727.3053
Where the site with a .asmx should say .Microsoft .NET Framework Version:4.0 etc...
