Can I declare namespaces in the web.config so that I don't have to write using statements for each namespace in each of my codebehind files?

Configuration :: Add Namespace In Child Web.config?

Mar 8, 2010

I have a really tricky problem that I just don't seem to find a fix to. I have looked "everywhere" and this is my last hope.
In the root I have a web.config with a few namespaces added in the <pages> tag.

Then, I will use one subfolder for every customer with a unique web.config for each customer. Thing is that the scripts on the sites depend on a specific class for each company, located in App_Code / CustomerSpecific / <customername> / CustomerConstants.vb

Every class is embedded in a namespace with the customers name. So, if we only had one customer then the web.config in the root could say:

add namespace="customer1"

But, my plan is that every web.config in each customerfolder shall state what company name to use.
Then I can read just this customer's settings in the vb from the right file depending on the namespace.

Here comes the problem, when I test this, the site in the customer folder only reads the namespaces in the root web.config (I have tested with appsettings though and they read perfectly even from the child web.config, so there's no problem in reading from it). So something seems to be the matter with adding namespaces in the root web.config and then adding others in the child web.config.

Before you answer; yes, I have tried with both <clear /> and <remove> specific namespaces and it doesn't work anyway. The namespaces in the root web.config seems to be overriding anyway.

Configuration :: Web.config AppSettings - Keys Referencing Other Keys?

Dec 7, 2010

My current project has many peripheral systems and many different environments (testing, integration, development etc). As expected, we're using .config files to dynamically manage everything.

Instead of updating each relavant key when deploying to an environment, I was hoping there was a way to change 1 key only. Such as:

<add key="Environment" value="Development"/>

<add key="WebServiceLocation" value="http://<<Environment>>/text.asmx"/>

I've done some searching and haven't come up with an elegant solution. I'm aware that .config files can make use of system variables, but this seems like a bit of a high wire act.

Namespace Removed In Web.config Not Removed In A Page With Master?

Sep 12, 2010

I have defined this in the web.config of a subdirectory

<namespaces>
<remove namespace="App"/>
<add namespace="Tom"/>
</namespaces>

App is imported in the parent web.config file, Tom and App have classes with the same names.To avoid errors resulting from ambiguous class names I removed the App namespace from the sub-directory where the Tom namespace is used.

However the namespace App is still imported on content pages that have a master page outside the Tom directory. This causes the aforementioned errors.Here is my dir structure

-Root Directory
--Default.master
--web.config (App is added in web.config)
--Tom Sub-diretory
---web.config (App is removed in web.config)
---Content page that uses Default.master (Here is the problem)
---Page without master (Works OK)

MVC :: The Type Or Namespace Name 'Controllers' Does Not Exist In The Namespace 'XXX' Error In VS2008

Jan 23, 2010

I use vs2008 and my MVC 1.0 and 2.0 Projects were working perfectly but all of a sudden i have an error on trying to compile all of them;

The error is of the form;

Error 1 The type or namespace name 'Controllers' does not exist in the namespace 'XXX' (are you missing an assembly reference?)

Error 3 The type or namespace name 'Models' does not exist in the namespace 'XXX' (are you missing an assembly reference?)

Error 4 The type or namespace name 'AccountController' could not be found (are you missing a using directive or an assembly reference?)

Error 5 The type or namespace name 'IFormsAuthenticationService' could not be found (are you missing a using directive or an assembly reference?)

Error 6 The type or namespace name 'IMembershipService' could not be found (are you missing a using directive or an assembly reference?)

These errors seem to come from the HomeControllerTest and the AccountControllerTest.

note that i recently installed Azure Tools using the Web Installer..Dunno if that could be the cause or problem.

Why Use Url.Content For Referencing Resources

Dec 10, 2010

In almost every ASP.NET MVC example I've come across, I always see Url.Content being used to reference CSS, JavaScript, and Images. Not once has anyone explained WHY to use it.

What's so bad about doing:

<img src="/Content/Img/MyImage.png" alt="My Image" />
<script src="/Scripts/jquery.js" type="text/javascript"></script>
<link href="/Content/Css/Default.css" rel="stylesheet" type="text/css" media="all" />
