View 3 RepliesI'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.
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?

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.
