Base class for view with RazorGenerator precompiled views

I have console project with some .cshtml files stored in Resources folder, which is built into .cs files with Razorgenerator.MsBuild nuget package.
I need to replace WebViewPage view base class for generated view, but adding web.config file with pageBaseType="ConsoleApp.MyViewBase" option set or changing location of files in different ways did not help me and no any other ways where found.
View class is always generated as:
public partial class _Resources_Index_cshtml :
System.Web.Mvc.WebViewPage<ConsoleApp.ModelClass> { ... }
Hope, there is some way to confgure the class globally for all views, without adding directives at the beginning of every .cshtml file.

It looks that that setting base view in web.config works in latest RazorGenerator.
So update your RazorGenerator package and try to have something like this in web.config:
<configSections>
<sectionGroup name="system.web.webPages.razor" type="System.Web.WebPages.Razor.Configuration.RazorWebSectionGroup, System.Web.WebPages.Razor, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35">
<section name="host" type="System.Web.WebPages.Razor.Configuration.HostSection, System.Web.WebPages.Razor, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" />
<section name="pages" type="System.Web.WebPages.Razor.Configuration.RazorPagesSection, System.Web.WebPages.Razor, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" />
</sectionGroup>
</configSections>
<system.web.webPages.razor>
<host factoryType="System.Web.Mvc.MvcWebRazorHostFactory, System.Web.Mvc, Version=5.2.3.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
<pages pageBaseType="WebApplication2.Views.BaseView2">
<namespaces>
<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" />
</namespaces>
</pages>
</system.web.webPages.razor>
In my case I was adding precompilation (with RazorGenerator.Mvc and RazorGenerator.MsBuild packages) to old project and it didn't work. The problem was that I had Version=2.0.0.0 in my configSections project and had to change it to Version=3.0.0.0.

If someone finds it helpful, there is a nuget package for this by me. It is same Razorgenerator.MsBuild but with replacing System.Web.Mvc.WebViewPage by Custom.System.Web.Mvc.WebViewPage. So if you want to use custom WebViewPage, install the package and add you class named WebViewPage in namespace Custom.System.Web.Mvc. Like:
namespace Custom.System.Web.Mvc
{
public abstract class WebViewPage<T>
{
...
}
}

Html.ActionLink reference error MVC4 in Areas

I've created an Area in my app called "Admin" and when I attempt to use #html.actionlink() to build some menu items I'm met with a reference error.
system.web.WebPages.Html.HtmlHelper does not contain a definition for ActionLink and the best extension method overload System.Web.Html.LinkExtensions.ActionLink(System.Web.HtmlHelper,string, string, string) has some invalid arguments.
This is the line of code that's generating the error.
#Html.ActionLink("Posts", "Index", new { area = "admin" });
I've googled around and attempted adding using system.web.mvc.html; with no benefit or change in behavior. I've checked the web.config file for the area and confirmed that both system.web.mvc and system.web.mvc.html are included in the namespaces, also to no avail.

You are using actionlink wrongly.
Below is the correct usage of actionlink(i m taking example of any arbitrary actionlink)
Html.ActionLink(article.Title, // <--Link Text
"Item", // <-- ActionMethod
"Login", // <-- Controller Name.
new { id = article.ArticleID }, // <-- Route arguments.
null // <-- htmlArguments
)
This uses the following method ActionLink signature:
public static string ActionLink(this HtmlHelper htmlHelper,
string linkText,
string actionName,
string controllerName,
object values,
object htmlAttributes)
The error is coming in your question because 3rd overload of Actionlink is controller name.
#Html.ActionLink("// Link Text //", "// Action Name //",// controller name //, new { area = "admin" });

You are missing a web.config in your /Areas/Admin/Views folder. Just create the basic one like below, the key part being the added namespaces:
<?xml version="1.0"?>

Enterprise library exception: Activation error occured while trying to get instance of type ICacheManager, key?

Using .net 3.5 and Enterprise library 5.0.
From my research, I found a similar issue here:
Activation error occured while trying to get instance of type ICacheManager, key "Cache Manager" *** this solution did not fix my issue.
I can't seem to figure it out, my config should be set up correctly, but keep getting the exception? Anyone have similar issues?
I made the suggestion to add cacheManager and reference when I call the cache manager:
using Microsoft.Practices.EnterpriseLibrary.Caching;
using Microsoft.Practices.EnterpriseLibrary.Caching.Expirations;
.....
....
ICacheManager cm = CacheFactory.GetCacheManager("TrackingCacheManager");
The App.config:
<configuration>
<configSections>
<section name="dataConfiguration" type="Microsoft.Practices.EnterpriseLibrary.Data.Configuration.DatabaseSettings, Microsoft.Practices.EnterpriseLibrary.Data, Version=5.0.414.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" requirePermission="true" />
<section name="cachingConfiguration" type="Microsoft.Practices.EnterpriseLibrary.Caching.Configuration.CacheManagerSettings, Microsoft.Practices.EnterpriseLibrary.Caching, Version=5.0.414.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" requirePermission="true" />
</configSections>

</backingStores>
</cachingConfiguration>

<connectionStrings>
<add name="ConnectionString" connectionString="server=AFS7BCBRNGQ5O0\DEVELOPMENT;database=EITC_RTS;Integrated Security=True"

</connectionStrings>
</configuration>
My references:

My guess is that you've setup this configuration in an App.config for your Domain project. But your main project has it's own config file which this configuration must be copied into.
So for example, if your main project was a webapp, then it would have a web.config. The caching configuration you have added to the App.config of the Domain project is not used at runtime. The configuration being used is from main project's config, in this example the web.config.
Copy your Caching configuration from the Domain App.Config to the main config file and it will work.

I have done silly mistake, but after read above, understand the issue. This is my vb.net code which give me the above error.
Imports System.Collections
'Imports System.Configuration
Public Class DatabaseLogic
Public ConnectionString = System.Configuration.ConfigurationManager.ConnectionStrings("db").ToString()
Public Function ServerDataMagic(StoredProcedure As String, PDMdata As Hashtable) As DataSet
Dim db As Database = DatabaseFactory.CreateDatabase(ConnectionString ) 'Here I am getting error.
Using cmd As DbCommand = db.GetStoredProcCommand(StoredProcedure)
Try
db.DiscoverParameters(cmd)
Catch discover_ex As Exception
End Try
and in web.config entry is
<add name="db" connectionString="Database=Dbname;Server=SERVER;uid=sa;pwd=sa#1234" providerName="System.Data.SqlClient" />
After read just get the issue is CreateDatabase method wants a config entry key as a string and I was given the exact connection string via config entry access. This is my updated code.
Dim db As Database = DatabaseFactory.CreateDatabase("db") 'Here I changed the config entry key
I was post to somebody help.

what will be the config section when adding a section to web.config?

I want to add domain key and value to my web.config for ldap authentication but when adding
<domain>
<add key="don" value="fffT"/>
<add key="LD" value="LDAP://n.tt.sg/DC=ttt,DC=xx,DC=exxxx,DC=sg"/>
</domain>
it shows the error could not find schema information of value and key. What should i write instead of
<section name="domain" type="System.Configuration.NameValueFileSectionHandler,System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" allowDefinition="MachineToApplication"/>

Do like this
<configuration>
<appSettings>
<add key="don" value="fffT"/>
<add key="LD" value="LDAP://n.tt.sg/DC=ttt,DC=xx,DC=exxxx,DC=sg"/>
</appSettings>
</configuration>
Put Key and values inside appSettings Section of web.confing

System.Configuration.NameValueFileSectionHandler is from System assembly, not System.Web.Extensions.
type="System.Configuration.NameValueFileSectionHandler, System, Version=3.5.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"

MVC3 Views unable to find added referenced class

My view is having issues finding a class located in one of my references.
This reference is to a dll built outside of the project.
The view always gives error:
The type or namespace name 'Company' could not be found (are you
missing a using directive or an assembly reference)
Here is the controller. No issues there.
using Company.Entities;
public ActionResult Find()
{
Person test = Person.SelectByADDistinguishedName("L*", false);
return View(test);
}
Here is the View. The error occurs in the #Model line.
#model Company.Entities.Person
#{
ViewBag.Title = "Bob";
}
<h2>Find</h2>
My Views/Web.config currently looks like this
<system.web.webPages.razor>
<host factoryType="System.Web.Mvc.MvcWebRazorHostFactory, System.Web.Mvc, Version=3.0.0.0, 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="Company.Entities" />
</namespaces>
</pages>
</system.web.webPages.razor>
I've checked similar threads like this one but to no avail.
Here is the message on the screen
Line 25: using System.Web.Mvc.Html;
Line 26: using System.Web.Routing;
Line 27: using Company.Entities;
Line 28:
Line 29:
Source File: c:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET
Files\root\49c9c7db\1f9dd5c8\App_Web_find.cshtml.a8d08dba.xro6gxci.0.cs
Line: 27
If I strip out any mention of the assembly (out of web.config - no #using statments). I get the same error message when loaded but against this line
public class _Page_Views_Home_Find_cshtml : System.Web.Mvc.WebViewPage<Company.Entities.Person> {

After working it with it for awhile, I ended up solving it.
I had to add the assembly under the assemblies section of the main web.config (not the one under the views)
Sample of the web.config.
<compilation debug="true" targetFramework="4.0">
<assemblies>
<add assembly="System.Web.Abstractions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
<add assembly="System.Web.Helpers, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
<add assembly="System.Web.Routing, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
<add assembly="System.Web.Mvc, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
<add assembly="System.Web.WebPages, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
<add assembly="Company, Version=2.0.31.0, Culture=neutral, PublicKeyToken=df9010405db60e6d"/>
</assemblies>
</compilation>
Thanks for people who gave me suggestions.

Be sure to check your views directory for an additional web.config file. I seem to remember running into a similar problem because I hadn't updated the correct web.config. YMMV.

Adding the reference
before where you use your control, in .cshtml file works. Example:
#model IEnumerable<MyApp.Models.MyModel>
#using System.Web.UI.WebControls;
But you can put it in web.config, under namespaces tag.
This way it is global to all views. Also, there is no need to specify the version:
<namespaces>
<add namespace="System.Web.UI.WebControls" />
</namespaces>
