Recently i have changed the namespace using the project properties. After that, application was compiling successfully, but at run-time it throws error "The type or namespace name ‘sample’ could not be found (are you missing a using directive or an assembly reference?)".
Error:
Line 23: using System.Web.Routing;
Line 24: using Sample;
Source File: c:\Windows\Microsoft.NET\Framework64\v4.0.30319\Temporary ASP.NET Files......\App_Web_index.cs Line:
I tried to locate the string “using Sample” and didn’t find anywhere in my solution.
Tried removing the temporary files from framework folder but no luck.
The problem was with my Web.config file
<system.web.webPages.razor>
<host factoryType="System.Web.Mvc.MvcWebRazorHostFactory, System.Web.Mvc, Version=5.2.3.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
<pages pageBaseType="System.Web.Mvc.WebViewPage">

<add namespace="System.Web.Mvc" />
<add namespace="System.Web.Mvc.Ajax" />
<add namespace="System.Web.Mvc.Html" />
<add namespace="System.Web.Optimization"/>
<add namespace="System.Web.Routing" />
<add namespace="Sample" />
</namespaces>
</pages>
I just replaced the old value "Sample" with new namespace name, and everything starts working again.
Answering so that anyone else has the same issue. There another web.config file under views. please change it there too.

I am using ServiceStack (self hosted) with Razor.
I have an issue trying to add System.Core to the namespaces in the web.config file.
Specifically, I get a compilation error if I include System.Core in the web.config.

System.Core is not a namespace its is an assembly
I happily run LinqPad 4.47.02 on a Win7 machine. I tried to add a EF5/dbContext connection. I choose my assembly, the class within the assembly and such assembly's config file. When I add the connection, i get this error:
The type initializer for 'System.Data.Entity.Internal.AppConfig' threw
an exception.
My app.config contains this:

I tried to comment the tag in configfile as suggested here but i get the same error.
As a side note, the connection worked and I have many saved linqpad queries. When I try to load and run one of them, linqpad crashes with no additional info.
What am I doing wrong?
Thank you,

(weird) SOLUTION:
I tried moving the <configSections> tag just before <system.data> tag and the error flied away
As per msdn article for configSections element:
If this element is in a configuration file, it must be the first child element of the configuration element
I believe that one of the reasons is that this element defines handlers to handle custom sections in the config so if it is first you don't need to read parse config multiple time to handle a case where a custom section is defined before the handler for this section is defined.
I am working in a modularized asp.net mvc4 project. Some views are located in a Class Library project. I already set the web.config to enable the intelligence in razor views. The #model, #Html.* and others are all working well. But when I try to reference a js file in my view by using the #Scripts.Render(). It says cannot find "Scripts". I checked the web.config file. The System.Web.Optimization is in the // node. I also installed Microsoft.AspNet.Web.Optimization package by Nuget.
I tried to type the code in a .cs file to use the System.Web.Optimization members, it works. But I cannot do same thing in the .cshtml file. Even when I typing #using System.Web.Optimization, it prompt me the Optimization cannot be found.
I am not sure what else I can do to resolve this issue. Any clues are very appreciated.
If you have a Web.config at the root of the class library, confirm it contains the following: <add namespace="System.Web.Optimization"/>
If you do not, trick Visual Studio into thinking that it is a web project and enable Intellisense and resolve your issue by adding a web.config file to the root of your class library project (the one that contains the Razor views) with the following contents (taken from this blog post) :
<configuration>
<configSections>

Getting System.Web.Optimization to work in a razor view within a class library
Reports are deployed and working, verified in Report Manager.
My application is an MVC2 app with my report on its own aspx page. This page worked with version 8 of the report viewer control, but we moved to new servers, upgraded sql server, and are trying to update our website to match.
The servers are Windows Server 2008 with IIS 7.5.
I am testing in both chrome and IE 9.
Despite my best efforts, I still get this error:
Report Viewer Configuration Error
The Report Viewer Web Control HTTP Handler has not been registered in
the application's web.config file. Add <add verb="*"
path="Reserved.ReportViewerWebControl.axd" type =
"Microsoft.Reporting.WebForms.HttpHandler,
Microsoft.ReportViewer.WebForms, Version=10.0.0.0, Culture=neutral,
PublicKeyToken=b03f5f7f11d50a3a" /> to the system.web/httpHandlers
section of the web.config file, or add <add
name="ReportViewerWebControlHandler" preCondition="integratedMode"
verb="*" path="Reserved.ReportViewerWebControl.axd"
type="Microsoft.Reporting.WebForms.HttpHandler,
Microsoft.ReportViewer.WebForms, Version=10.0.0.0, Culture=neutral,
PublicKeyToken=b03f5f7f11d50a3a" /> to the system.webServer/handlers
section for Internet Information Services 7 or later.
But, I've already done this. in fact, I even read this from MSDN:
To use IIS 7.0 in Integrated mode, you must remove the HTTP handler in system.web/httpHandlers. Otherwise, IIS will not run the application, but will display an error message instead.
Just to be safe, I tried a combo of neither while adding the handler into IIS directly, just the web server http handler in my config, just the http handler in my config, and both.
Let's start with my web.config
<configuration

</handlers>
</system.webServer>
</configuration>
I have the assemblies, the build provider, and the handler. What else could be wrong?
I found a quick and dirty workaround - to your web config add this:
<location path="Reserved.ReportViewerWebControl.axd">
<system.web>
<authorization>
<allow users="*" />
</authorization>
</system.web>
</location>
I saw in fiddler that for some reason when page requested Reserved.ReportViewerWebControl.axd instead of getting HTTP 200 response server would send 302 - moved to login.aspx?returnurl="Reserved.ReportViewerWebControl.axd. So allowing all users to the handler path solves the problem.
I thought its ReportViewer Rendering Issue on IIS7
I have manually mapped my reportviewer handle to IIS7 like this:
•Open Internet Information Services (IIS) Manager and select your Web application.
•Under IIS area, double-click on Handler Mappings icon.
•At the Action pane on your right, click on Add Managed Handler.
•At the Add Managed Handler dialog, enter the following:
Request path: Reserved.ReportViewerWebControl.axd
Type: Microsoft.Reporting.WebForms.HttpHandler
Name: Reserved-ReportViewerWebControl-axd
•Click OK.
also changed by web config by adding
Still mine's not working. I thought the above solution would help others.
I have tries this by removing unwanted mvc assemblies from asp.net project. So the simple solution was to remove WebMatrix.*.dll from Bin folder in web project as that belongs to mvc framework.
First, my development environment: Win7 laptop with Visual Studio Professional 2010. IIS is NOT installed.
I'm trying to turn on and set up some roles for user management via the ASP.NET Configuration Tool, as demonstrated in the MVCMusicStore tutorial. When I click on the 'Security' tab, I get the following error:
"There is a problem with your selected data store. This can be caused by an invalid server name or credentials, or by insufficient permission. It can also be caused by the role manager feature not being enabled. Click the button below to be redirected to a page where you can choose a new data store.
The following message may help in diagnosing the problem: Could not load type 'HandiGamer.MvcApplication'."
When I click on the 'button below', it tells me I'm using AspNetSqlProvider as my provider. When I try to test it, it tells me:
"Could not establish a connection to the database.
If you have not yet created the SQL Server database, exit the Web Site Administration tool, use the aspnet_regsql command-line utility to create and configure the database, and then return to this tool to set the provider."
Here's the thing:
The MVCMusicStore demo's role/user management works when I run it through the debugger. I can add myself as a customer, and add/remove items from my cart. Despite this, when I attempt to use the Configuration Tool with it, I get the same errors.
I actually have run aspnet_regsql on my copy of SQL Server 2008 Express. It created the necessary tables for user management. Still didn't fix my problem.
I'm just wondering if I'm missing something obvious, as the tutorial essentially said "Click two buttons and you're all set." It literally said nothing about setting up the db for this.
I'm just stumped at this point. Role/user management works (the MVCMusicStore proves that it does), but the configuration tool won't let me turn it on, set it up, or otherwise edit how it works. It's becoming very frustrating. Any help would be greatly appreciated.

Found the solution. Had to compile/build my solution before the config tool would 'see' the db security stuff.
