I am developing a website which will be having both asp.net pages and MVC pages in it, So I have BaseWebPage class which will be used for both asp.net pages and MVC Views. but My BaseWebPage class is inherited from System.Web.Mvc.ViewPage, So Will there be any code/ functionality break for normal asp.net pages, because System.Web.Mvc.ViewPage is overriding some of the Pagelife cycle methods.

I can have a base class for views in an MVC project like this:
public class BaseViewPage : System.Web.Mvc.ViewPage
{
public string Something { get; set; }
}
And then in the ASPX I can do this:
<%@ Page Something="foo" Language="C#" Inherits="MyNamespace.BaseViewPage" %>
This works fine; the problem is when I try to do the same with the generic version:
public class BaseViewPage<TModel> : System.Web.Mvc.ViewPage<TModel> where TModel : class
{
public string Something { get; set; }
}
When I try to use this from the ASPX, like this:
<%@ Page Something="foo" Language="C#" Inherits="MyNamespace.BaseViewPage<SomeClass>" %>
I get the error message:
Error parsing attribute 'something': Type 'System.Web.Mvc.ViewPage' does not have a public property named 'something'.
Notice how it tries to use System.Web.Mvc.ViewPage rather than my BaseViewPage class. To make it more interesting, if I remove the "Something" attribute from the Page directive and put some code in the generic version of BaseViewPage (OnInit for example) the class is actually called / used / instantiated.
So, am I doing something wrong or is this a limitation.

I am getting this compilation error"
All my pages are receiving this error - website is down; here's the code:
[Code]....
Except my web config file shows linq is accounted for? [Code]....
I would note that I updated to VWD Express 2010 then had to revert back to 3.5 because my host at Arvixe had not updated my server yet. He then said he updated it and I reverted up to 4.0 again. It turned out he hadn't and I tried to revert back...and then this showed up and numerous other errors.

This may seem like a really simple question, but can I use the System.Threading namespace in ASP.NET web forms? I have a web page which uses HTTP GET/POST to gather page customisations (title, subtitle, etc.) from the user and numerical input which is passed to a ASMX web service. Currently they work sequentially, the customisation first followed by numerical processing. So can I use threading to do this?

I am using vb.net/VS.Net 2008/3.5. I am trying to Import the System.Web.Profile namespace like so:
<code>
Imports System.Web.Profile
</code>
However when I add that in I get a green squiggly error line that when hovering over shows me "Namespace or type specified in 'System.Web.Profile' doesn't contain any public member or cannot be found. Make sure the namespace or type is defined and contains at least one public member. Make sure the imported element doesnt use any aliases" When I use intellisense I see only three namespaces for system.Web, which are:
<code>
Imports System.Web.AspNetHostingPermission
Imports System.Web.AspNetHostingPermissionAttribute
Imports System.Web.AspNetHostingPermissionLevel
</code>
Do I need to add a reference in order to see System.Web.Profile?

This started as Could not load type 'Global' error. After I tried a few things and getting no where I deleted the Global.asax file and now the error is Could not load type '[namespace].???'Where ??? is the class name of every page I try to load.The web site (when executed within VS2008, local dev computer) works fine but once published (with no errors) and deployed to the server gives me Could not load type '[namespace].???' error
I did install elmah and I was able to get more details for this "generic" Could not load type '[namespace].???' error
elmah reports a HTTP error 500 :
System.Web.HttpException Could not load type '[namespace].???' ->
System.Web.HttpParseException: Could not load type '[namespace].???'
I have checked the "basics"
References
Doing a clean and a build Checking the Inherits attr in the HTML against the code behind
UPDATE #1 I did deploy the site to a different DEV computer (configured IIS, virtual folder, etc.) and it works. When I use the same published code on the server, get the generic Could not load type '[namespace].???' error
UPDATE #2 I created a test web app. One form (Default.aspx) with a button. The click event does a Response.Write("Hello World"); I moved this app to the server and guess what, I get the Could not load type TestSite._Default
UPDATE #3 According to the fusion log viewer, these two websites are attempting to load CppCodeProvider and VJSharpCodeProvider, but I have no references to any of these. After a Google search, I found this post.I checked and I have no references to JAVA files.

I am trying to write a macro that accesses an XML file external to the editor.
For some reason, I am getting error messages on everything within the System.XML namespace
'Type XmlDocument is not defined'
'Type XmlTextWriter is not defined'
'Type XmlElement is not defined'
( etc... etc... etc... )
I've imported the namespace at the top of the editing context within the macro IDE:
Imports System.XML
I have also tried to reference the namespace members with a complete namespace reference:
System.XML.XmlDocument
It didn't work. It is still being indicated as undefined.
I've tested the code from within a stand-alone console app, and it works fine.
From this, am I to conclude that the System.XML namespace is not accessible from the macro facility?
Is there another option?

I want to use the DataContractJsonSerializer class. This is contained within theSystem.Runtime.Serialization.Json namespace and the System.ServiceModel.Web dll.or some reason, when I add the using directive for the namespace, Visual Studio says it doesn't recognise the Json namespace in System.Runtime.Serialization.When I try to add the System.ServiceModel dll, nothing happens, which suggests to me it's already referenced. (Because nothing also happens when I try to add a reference to System.Web which is definitely referenced!)

I'm getting a warning in my page directives saying that this namespaceystem.Web.UI.DataVisualization.Charting isn't found. I went to add a reference to the project so I could import the namespace and this namespace does not exist in the .NET tab. What do I need to do to get this working? Also, even if I add this to my Global Assembly Cache, that won't do anything for the web host web server that my website is publically on.Any guidance on this? How to get it on my local machine as well as understanding that it'll work on the actual web server?
