In my windows service I have 2 web references
My windows service only contains an app.config not a web.config
my app config looks like this:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<configSections>
<sectionGroup name="applicationSettings" type="System.Configuration.ApplicationSettingsGroup, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" >

the problem is my web services when i click on them the URL field is still saying
"Web reference URL" http://PROD/web/services/XAXSSTRN.XAXSSTRNHttpSoap11Endpoint

what is the end goal? To release this windows service to dev and prod environments without having to rebuild the entire solution.
The ideal behavior is :
Build the latest code in dev mode (test it, if all test good then , step 2)
Provide an app.config file with prod urls to dropped inside the
folder
Release
As you can see what I am trying to avoid is the need of dropping the file manually changing those 2 web services , rebuilding the solution AND THEN releasing...
Classic ASP.NET apps get their configuration from a hierarchy of web.config values. Other apps (console applications, Windows Forms apps, WPF, Services, ...) get their configuration from a configuration file named [NameOfExe].exe.config (and occasionally from [NameOfAssembly].dll.config. That file is located in the same folder as the exe itself.
For example, if your service is MyWcfService.exe, you will very likely find a MyWcfService.exe.config file in the same folder (for example, in the bin/debug folder). Its contents should be the same as your app.config.
Visual Studio makes this all "just work" by creating an app.config file in your source folder and then, at build time, copying the contents of that file to the appropriately named [NameOfExe].exe.config file in the same folder as the EXE.
In the normal case, you might have one set of URLs (and perhaps other data) for your dev environment, another for QA, another for Integration Test and another for Prod. You can manage this through the use of configuration transforms.
I think this goes some way towards answering your questions. In summary
App.config files have nearly the same capabilities as web.config
files
App.config files get "compiled" to [NameOfExe].exe.config
files at build time and placed in the same folder at the EXE
Configuration transforms may help you out with managing your URLs
Your other choice is managing a set of [NameOfExe].exe.[Environment].config files and manually putting them in the right place.

I have had to add a monoSettings section to my Web.config file as I need to support colons in the url (similar to this question: ASP.NET special characters in URL (colon) not working even with requestPathInvalidCharacters="").
Now when I run my web-api service in visual studio (which I do for ad-hoc testing) it gives an error:
"The configuration section 'monoSettings' cannot be read because it is missing a section declaration"
I'm just wondering what is the best way to support this config in my Mono service without impacting being able to run in on Windows? Can I just flag it as optional or unimportant so that it won't fail when trying to read the config? Or is it just better to have a different build configuration for Mono - but I'd then have to maintain two versions of web.config with just this one minor difference.
I resolved this issue by adding a configSection to my Web.config as follows:
<configuration>
<configSections>
<sectionGroup name="system.web">
<section name="monoSettings" type="DataSetSectionHandler,SectionHandlers" />
</sectionGroup>
</configSections>
<system.web>
<monoSettings verificationCompatibility="1" />
<httpRuntime requestPathInvalidCharacters="<,>,*,%,&,\,?" />
</system.web>
</configuration>
I have an app.config file in Winforms application that holds a connection string. This is to go out to multiple tenant (clients) as a separate file. These clients have different database sources. This config file also holds other version information such as EF, Telerik reporting etc...
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5.1" />
and
<section name="Telerik.Reporting"
type="Telerik.Reporting.Configuration.ReportingConfigurationSection, Telerik.Reporting, Version=8.1.14.804, Culture=neutral, PublicKeyToken=a9d7983dfcc261be"
allowLocation="true" allowDefinition="Everywhere" />
The problem I have is when we have an updated version of EF or Telerik reporting with our application and we deploy (auto-deploy) this we need to overwrite the app.config file in the client directory to update the versions in the client config file. They then lose their connection setting and I do not want the client to have to go and re-enter it.
My question:
Is there a best practice to overcome this issue? Should I hold the connection string somewhere else?
Yep, the best thing to do is to move your connection strings section to an another config file and reference that file within your app.config.
For example create a new file called connectionStrings.config:
<connectionStrings>
<add name="Default" connectionString="[client_connection_string] "/>
</connectionStrings>
And in your app.config file:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<connectionStrings configSource="connectionStrings.config" />
</configuration>
A full example can be found here.
Use an external configuration file that is referenced from the application config file. E.g. include this section in your config file.
<configuration>
<connectionStrings configSource="connections.config"/>
</configuration>
The external config file is described http://msdn.microsoft.com/en-us/library/ms254494(v=vs.110).aspx
Note that storing connection settings in plaintext on a workstation is still a bad idea.
Using Windows registry for stuff like this is a definite no-no these days.
you can try to hold all connection data that you need in separate xml file so it dont get overwrite when you preform a deploy of updated version.
I have a solution which has a WinForm application (Project 1) which makes use of a Class2 from another Class Library project (Project 2). Project 2 makes use of a class3 which is defined in another Class Library project (Project 3).
I know I can override application settings of Project 2 from my Main WinForm application, but, my question is, can I override application settings which were defined in Class Library Project (Project 3) from my main WinForm application (Project 1)
I know it looks like Im making things complicated, but I had to override application settings of Project 3 from my main application.
Can anyone put some light in this direction and suggest how to resolve this?
FYI...
When you add a setting.settings file, it will automatically creates a app.config file and we can configure applicationSettings from Setting.settings UI in VS. Below is the app.config file content from Project3 whose applicationSettings Im interested to override in another WinForm project.
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<configSections>
<sectionGroup name="applicationSettings" type="System.Configuration.ApplicationSettingsGroup, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" >
<section name="Project3.Settings" type="System.Configuration.ClientSettingsSection, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
</sectionGroup>
</configSections>
<applicationSettings>
<Project3.Settings>
<setting name="SettingInProject3" serializeAs="String">
<value>TempPath</value>
</setting>
</Project3.Settings>
</applicationSettings>
</configuration>
What modifications in app.config file of WinForm application can override the settings defined in Project3 class library.
The hierarchy of references goes something like this. WinForm>Project2DLL>Project3DLL.
Please let me know if further information is needed.
Open the settings in the source project in visual studio, Ensure the Access modifier (at the top) in the settings viewer in visual studio is set to public. Now these settings will be accessible from your external projects.
Let's say we have Assembly1 and Assembly2.
Assembly2 is a C# class library used by Assembly1.
Web and Service References are configured and stored in Asembly2/app.Config.
Moreover, the EF connection string(s) are in Assembly2/app.Config.
When I use Assembly2 in Assembly1, the Assembly2 config file is not used. In fact, in that scenario, only the Assembly1 configuration appears accessible through default means.
As a result, I have to copy the Assembly2 config contents into the Assembly1 config.
This has worked for me for many projects.
Is there another way? A better way?
It seems wrong to have repeating configuration data.
Do you have a recommendation or technique that works?
Thank you.
You need to apply changes to the config file of entry point exe assembly. Class library assembly (dll) config files are never used. They are made by Visual Studio so you could easily copy the settings to exe config files if needed.
Bellow is example of the config file for exe assembly that has both, settings from class library ClassLibrary1 and settings from the exe assembly MainAssembly. You can see that both connection strings are in one connectionStrings settings. However, if you need to set other settings, beside connection string, you need to add extra section.
If you are already using this technique, this is correct way to go. This technique is flexible. For example if you have more than one project having the same connection strings on one box, you could specify the connection strings in machine.config file. You can also override the settings in some projects if needed.

A DLL (or another referenced assembly) is not meant to carry it's own app.config, but rather have everything configured by the caller. So everything should go into the app.config of the exe.
Consider for example a shared data access library that needs connection strings to the database. The library should be possible to use from a variety of applications with different connection requirements. Having the connection string tied strictly to the shared library wouldn't work, it has to be done at the client using the library.
It is possible to put systemwide settings that affect all applications running on a machine in the machine.config file, but use that approach with caution as it will affect all applications on the machine.
I've got a bunch of DLL projects that I'm pulling into my application, each contains their own Settings.settings/app.config. When I compile the app and run for debugging, everything works just fine, but come deployment time I can't get my DLLs to read their own settings files.
I've been doing some reading and it has become apparent that there's a couple of methods to getting each dll to read its own configuration - one is to dedicate a .dll.config to the library and the other is to embed the dll's configuration in the process.exe.config.
I'm having significant issues trying to implement either and I wondered if anyone has any good docs on this - there appears to be a shortage on the Net.
I'd like a separate .dll.config for each of the libraries if possible, but in a pinch, getting each of my libraries to read their own section of the process.exe.config will do.
Can anyone point me in the right direction because I'm so close to rolling this application out but this stumbling block is causing me a significant headache.
Edit: When I merge the configuration files, I start getting TypeInitializer exceptions when I initialize objects withing my libraries. This is likely just me being retarded, but does someone have a working example of a merged config file and some basic demonstrative code for reading it from multiple assemblies?
What are the "significant issues" you encountered? I started with embedding the dll's config in the exe's config, which worked, but was cumbersome. I now have all the config stuff in one dll project. The only thing I needed to do to make that work (besides copying the settings over) was to change the Settings class to be public.
Here's an example of a merged app.config that works:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<configSections>
<sectionGroup name="applicationSettings" type="System.Configuration.ApplicationSettingsGroup, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" >
<section name="SharedConfig.Client.Properties.Settings" type="System.Configuration.ClientSettingsSection, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
<!-- Begin copy from library app.config -->
<section name="SharedConfig.Library.Properties.Settings" type="System.Configuration.ClientSettingsSection, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
<!-- End copy from library app.config -->
</sectionGroup>
</configSections>
<applicationSettings>
<SharedConfig.Client.Properties.Settings>
<setting name="Bar" serializeAs="String">
<value>BarFromClient</value>
</setting>
</SharedConfig.Client.Properties.Settings>
<!-- Begin copy from library app.config -->
<SharedConfig.Library.Properties.Settings>
<setting name="Bar" serializeAs="String">
<value>BarFromLibrary</value>
</setting>
</SharedConfig.Library.Properties.Settings>
<!-- End copy from library app.config -->
</applicationSettings>
</configuration>
Have each class library define configuration settings in a custom ConfigurationSection.
Then add custom section handlers to your process.exe.config file.
This MSDN article is pretty comprehensive in its explanation, with examples in both VB and C#.
See If app.config for a DLL should be in the "main config"… what do we do with WCF References in DLLs?. The real answer is "copy and paste". That's unfortunately the general solution Microsoft had in mind. In some cases, the .NET 2.0 Settings mechanism can be used, as it bakes the default values into the DLL itself. At runtime, the DLL can then save updated settings - into the .exe.config.
