Visual Studio :: Type Or Namespace Cannot Be Found Error - How To Rectify It

Jan 28, 2011

I started an app in VS2008. I did it as a web site. I installed VS 2010 (yay) today. I wanted to start over as a web project. I made a Master Page. I made content pages. One of my content pages has a form on it. Super simple text boxes and submit.


I added a folder called App_Code and placed my class files there by doing Add New Item and pasting the code into the new class. I have person and persons. The persons collection class references person. In the same folder, the persons class finds the person class. Up one level in a page's code behind, I am gettingthe error

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

For giggle, I move person.cs up a folder. Still cannot find the person. Persons collection class still CAN find person. My code behind cannot find it.

A little reading tells me I have to set that folder as an app folder in IIS. I am running Windows 7 ersonal... I cannot find IIS. If not there, I ask myself what they heck is my app running under?

for being such a noob. Anyone know what is going on here?

Visual Studio :: The Type Or Namespace Name 'SilverlightShowHeader' Could Not Be Found?

Mar 25, 2011

I have an asp.net web site. The reason I'm using web site instead of web application is that my project uses Sitefinity CMS system which uses the web site model.

I have several web user controls (ascx and code behind). I need a reference in the code behind of one control to another. I'm using the following code:

[Code]....

SilverlightShowHeader is the name of the class (the second control) which I need to reference. I haven't set any namespaces for both controls.

When I try to build the web site it shows the following error:

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

Is that normal and how can I avoid it?

Web Forms :: Error Message / The Type Or Namespace Could Not Be Found

Feb 15, 2010

I'm very, very new to the asp.net world and I was running through the create the movie db tutorial that is located in the learn asp.net mvc section of this website. Everything is fine until I create my home controller and edit it like on the site. Here is the first part of the code I have that has the error in it:

privateMoviesDBEntities _db = new MoviesDBEntities();

This is all on one line in visual studio but i get an error saying that the type or namespace 'MoviesDBEntities' could not be found (are you missing a using directive or an assembly reference?). I have checked the spelling and I have the using MovieApp.Models; up above so if anyone has any insight that would be great.

I have also tried performing the manager contact sheet tutorial and get the same error in this section of the code.

C# The Type Or Namespace Name 'Anywhere' Could Not Be Found?

May 26, 2010

I know that this sounds like a simple referencing problem from the title this is becoming a nightmare!I have a code class that uses the "iAnywhere.Data.AsaClient.dll". This Dll is referenced in the project and in the code class I have added this dll in the Using section.Everything seems fine at build with no errors at all but when I go to run the application it comes up with the following Compilation Error: Compiler Error Message: CS0246: The type or namespace name 'iAnywhere' could not be found (are you missing a using directive or an assembly reference?)The line that the Error points to this line in the class:using iAnywhere.Data.AsaClient;I have set the dll to copy local and it makes no difference, the Dll is installed on my PC so is in the GAC, I use this Dll with many other C# projects and have no problems.I have scoured Google looking for an answer and haven't found anything that points me to an answer to my problem.
