I am trying to extend the default webrole template. I have added a new entity model and created a skeleton framework for it. When the loading of the index page is attempted, a server error is displayed.
"The type 'Microsoft.WindowsAzure.ServiceRuntime.RoleEntryPoint' is defined in an assembly that is not referenced. You must add a reference to assembly 'Microsoft.WindowsAzure.ServiceRuntime, Version=2.3.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'."
I have double checked that the WebRole includes this reference and it does. I can fix this error by setting this reference Copy Local property to true.
If I do this, the error changes to "The type name 'Models' does not exist in the type 'WebRole.WebRole'"
Both errors are thrown from the Index.cshtml file, specificially on the line:
public class _Page_Views_BankAccount_Index_cshtml : System.Web.Mvc.WebViewPage<IEnumerable<WebRole.Models.BankAccount>> {
What is causing this?
You are missing references in your view compilation.
The view compiler uses a different set of references, and to make your model work you will need to add the references in your web.config
For example:
<configuration>
<system.web>
<assemblies>
<add assembly="YourAssembly, Version=4.0.0.0, Culture=neutral, PublicKeyToken=TOKENKEY" />
</assemblies>
</system.web>
</configuration>
I know it's old but might help anyone else.
This error occurs due to a conflict in the default project for Windows Azure Cloud Service when the web project is created with the name WebRole (Which puts the project in the same namespace as the Microsoft.WindowsAzure.ServiceRuntime dll).
To fix there are two easy options:
replace this code
#model WebRole.Models.RegisterViewModel
and add the using statement and your model without the namesapce
#using WebRole.Models
#model RegisterViewModel
Or instead one can add a namespace in the web.config inside the views folder (not the one in the root)
<pages pageBaseType="System.Web.Mvc.WebViewPage">
<namespaces>
-----
<add namespace="WebRole.Models" />
</namespaces>
</pages>
And on your views just replace the existing code with
#model RegisterViewModel
Hope it helps.
Do you have the correct version of Azure Tools installed? I know for me, I only get this error when I'm missing the Azure Tools library.

I am deploying a new website as my main site and it works beautifully.
All of my applications under the root url work as well, except for one. It is a legacy system (c#.net) that is heavily used and unfortunately, I do not have access to the source code.
When I run the legacy application www.mysite.com/crm I get the following error:
Server Error in '/crm' Application.

The error is listing the web.config for the main site, which works. However, it happens only when I run the application under the main site.
This is running on Server 2008 R2 and IIS7
How do I correct this? What else can I try?
UPDATE
I don't know if it makes a difference, but the Web.Config it references in the error is for the new website, not for the legacy application. I am not sure why the main site config is a factor at all.
CLARIFICATION
I don't have access to the source code of the legacy application so I cannot adjust the properties for that application. Pasting the Optimization dll into the site didn't fix it either. It may work for other users, but not for me.
WORK AROUND
I setup the new site under another URL and redirect traffic to the root URL to the new URL and allow the legacy application to run as is until we can replace it. Very sloppy solution, but it works for now.
I just faced this issue now:
I reinstalled the optimization framework and everything worked fine:
Install-Package Microsoft.AspNet.Web.Optimization
I faced same problem after create a new area in MVC5. There is auto generate web.config file. Check your web.config file under Views folder there is a line
<add namespace="System.Web.Optimization" />
if you need this then install it using following command.
Install-Package Microsoft.AspNet.Web.Optimization
at Package Manager Console like below
If you think no need then simply remove <add namespace="System.Web.Optimization" /> line from following section in web.config file
<namespaces>
<add namespace="System.Web.Mvc" />
<add namespace="System.Web.Mvc.Ajax" />
<add namespace="System.Web.Mvc.Html" />
<add namespace="System.Web.Routing" />
<!--<add namespace="System.Web.Optimization" />-->
<add namespace="AutoParts.Web" />
</namespaces>
Check the Bin folder for the legacy application. It may simply need you to drop in that DLL. The System.Web.Optimization namespace exists as of ASP.NET 4.5 so it may not even be supported. The legacy App might be older than that.
In Visual Studio .. Go to your project and see the References tree.
right click System.Web.Optimization and choose Properties
look for the path , you will find it empty
if that is the case then
look in your PC for the file names System.Web.Optimization.dll and copy it in the bin folder of your project and that will resolve it
I was just experiencing: "CS0234 C# The type or namespace name 'Optimization' does not exist in the namespace 'System.Web' (are you missing an assembly reference?)" and found this stackoverflow page. -- The cause for me was due to me renaming the web form (aspx page) I was working with, I also wanted to rename the public partial class behind that form. Doing so resulted in the mentioned error code. I added "using System.Web.Optimization;" to the code behind (C#), "cleaned" the solution, then "built" then solution, then "rebuilt" the solution and now the error is gone and that using statement wasn't being used, so I got rid of it. My solution no longer has that or any errors so I figured I'd share this weird story. I probably didn't need to use that "using" statement, but whatever.

I'm trying to implement the Styles.Render method in a project of mine and I am using the separate, pre-built MVC 4 internet application project that's created from the New Project wizard as my model. In the pre-built MVC website's _Layout.cshtml layout view, the following code appears within the head tag:
#Styles.Render("~/Content/css")
However, in my own project, just using the #Styles.Render syntax does not seem to work. For some reason, the view does not like it. And I have to resort to using the fully qualified version of the method:
#System.Web.Optmization.Styles.Render("~/Content/css")
I would like to know what am I missing or how can I avoid having to use the fully qualified type and member syntax from within a Razor view in the manner of the pre-built version as described above? Thanks.
You're missing the System.Web.Optimization namespace reference in the web.config in the views folder
<configuration>
<system.web.webPages.razor>
<pages basePageType="...">
<namespaces>
<add namespace="System.Web.Optimization"/>
</namespaces>
</pages>
</system.web.webPages.razor>
</configuration>
I'm having an issue where I keep getting error message CS0246 on my web server, but not in my visual studio environment. The issue is coming from a dll I reference in my project. The server cannot find my namespace for my dll.
To solve this I tried copying every file in my project directory to my web server, adding a tag in my web.config file, and adding an import statement in my aspx page. I have also tried adding an assembly reference in my aspx page, but that seems to require a change in the registry which I don't think I have access to.
I should also note my dll and namespace name are different, but changing the names of either did nothing. I also completely removed the dll and copied the code files directly into my project, but it still could not find the namespace.
I thus think I'm supposed to register the namespace and dll somewhere else, but I cannot figure out where. Any help will be appreciated.
If it matters, both my web project and dll are using .NET2.0
I know this is the equivalent of the annoying "did you reboot", but have you tried making a new solution and re-adding the projects and references? Sometimes the .sln file can get corrupted.
Sometimes, the web.config file contains instructions for the .NET framework to generate temporary files.
Please check your config file for something similar to:
<system.web.webPages.razor>
<host
factoryType="System.Web.Mvc.MvcWebRazorHostFactory, System.Web.Mvc, Version=5.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
<pages pageBaseType="System.Web.Mvc.WebViewPage">
<namespaces>
<add namespace="System.Web.Mvc" />
<add namespace="System.Web.Mvc.Ajax" />
<add namespace="System.Web.Mvc.Html" />
<add namespace="System.Web.Routing" />
<add namespace="YourNamespace.ShouldBeCorrect.Here" />
</namespaces>
</pages>
</system.web.webPages.razor>
This is likely the case if your error page contains a reference to a dynamically generated file such as:
Source File: c:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files\root\133f2363\4ba6d0ba\App_Web_index.cshtml.a8d08dba.ociepbng.0.cs Line: 27
I am unable to use RoleEnvironment.CurrentRoleInstance.Id in cshtml file of mvc 3 razor. An error for RoleEnvironment says that it does not exist in the current context. However, I have added the namespace as below in web.config file of Views folder. Note that "Microsoft.WindowsAzure.ServiceRuntime" namespace is added as the last namespace. Could you please let me know how to fix this? I want to output the current instance's id on the top of the page for every page without having to code in all pages.
So its compiling and executing correctly? Are you sure you are starting the azure project (so it runs under the Compute Emulator) and not starting the site directly for debug?
I just tried it and it works fine for me, had to add this to config:
<system.web>
<compilation debug="true" targetFramework="4.0">
<assemblies>
<add assembly="Microsoft.WindowsAzure.ServiceRuntime, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />
And my view _Layout.cshtml:
#using Microsoft.WindowsAzure.ServiceRuntime
#RenderBody()
#RoleEnvironment.CurrentRoleInstance.Id
And in my debug I get something like (AzureDelete was my project name):
deployment(1).AzureDelete.MvcWebRole1_IN_0
I've registered a control in my web.config file and the .dll for the control has been placed in the application's Bin folder.
<compilation debug="true">
<assemblies>
<add assembly="System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
<add assembly="RichTextEditor"/>
</assemblies>
</compilation>
<pages>
<controls>
<add assembly="RichTextEditor" namespace="RichTextEditor" tagPrefix="cc1" />
</controls>
</pages>
I can now use this control in .aspx pages in the application root folder without issue. However, some of the .aspx pages I want to use this control in are stored in a sub-folder of the application (In this case a sub-folder called "Admin"). When I try to use these controls in these pages and run in debug I get an error of:
Error 1 Unknown server tag 'cc1:RichTextEditor'. N:\IntranetV2\admin\EditMenuItem.aspx 27
I'm sure I'm missing something simple here but I can't seem to figure out how to get this working and googling doesn't seem to have helped much.
UPDATE:
Okay I've tried Aaron's solution with no luck, I amended his code suggestion to:
<add tagPrefix="cc1" tagName="RichTextEditor" src="~/Bin/RichTextEditor.dll" />
I hoped this would be all that's required however I now get the error:
Error 1 There is no build provider registered for the extension '.dll'. You can register one in the <compilation><buildProviders> section in machine.config or web.config. Make sure is has a BuildProviderAppliesToAttribute attribute which includes the value 'Web' or 'All'.
Please can someone help! I know the answer to this must be ridiculously simple but I'm going mad trying to fix it myself and google has proved no help.
I had some similar problems a while back. Only way I was able to get the control working was something like this:
<add tagPrefix="cc1" tagName="RichTextEditor" src="~/controls/richtexteditor.ascx">
rather than this:
<add assembly="RichTextEditor" namespace="RichTextEditor" tagPrefix="cc1" />
EDIT:
Since you're using a binary, add the .dll to your solution, and add a reference to it in the project where you're using it. This way, .NET will add the .dll to your bin folder. Then, go back to this (and verify that the namespace and assembly are correct):
<add assembly="RichTextEditor" namespace="RichTextEditor" tagPrefix="cc1" />
Also, check this out as a reference: Tip/Trick: How to Register User Controls and Custom Controls in Web.config
Is the folder defined as an application in IIS? That would cause such a problem since in that case IIS will look for web.config (as well as bin/ and other special files and folders) inside that subfolder.
