i try to learn learn Dynamic Data Entties . i see some sample about it. they try to teach some codes in App_code. i really want to learn where is my Ap_code?
Web Applications do not use the App_Code folder, only Web Sites. If you want to use the App_Code folder create a Web Site instead of a new Web Application.
If you want to use a Web Application you can place the .dbml file anywhere, you'll just have to fully qualify (with namespaces) the DataContext wherever you want to use it (ex: in the Global.asax file).
It seems it is not possible to create the app_code folder. Take a look at the bottom of this page in the community content part. There are a lot of people with the same problem.
SOLUTION: add the .dbml to file root of the site
As mentioned above, a web app project does not create an App_Code folder by default. You can create one using the solution explorer though if you want - right click on web project, new folder..., name it App_Code.

Ive got an aspx file, containing report viewer and im trying to open the file using controller. If i put the file in the root, it works using redirect but if i placed it in the Views folder, it wont open. Appreciate any help and thank you in advanced for your help.
The ~/Views directory has a directory-specific Web.config file that adds a rule that prevents all direct-access to files in that directory tree.
To serve WebForms pages in an MVC project you need to move it to another directory that lacks the Web.config rule (e.g. ~/Content), or disable the rule (not recommended).
Your .aspx file doesn't belong in the ~/Views directory anyway as it is not a View (in the MVC architecture) - it's a "page" :)
Note that your project will not work in ASP.NET Core as support for WebForms has been removed in that version.
My Asp.Net MVC project's folder structure is as shown above.Could you tell me how to access the web project's event-images folder from the webapi project ?
I have implemented where I can access the webapi's event-images folder as shown below. Now I need to access web project's event-imagesfolder.How can I do that ? Thanks in advance.
var path = System.Web.Hosting.HostingEnvironment.MapPath("~");
var pathToEventImage= path + "\\Resources\\images\\event-images\\"
How about:
HostingEnvironment.ApplicationPhysicalPath
Described here: msdn
And then navigating to the Web project from there.
Another way is to go to Resources in the API project right click on the folder and choose Add -> Existing Item.. then browse the Web folder and have it in both projects
Another way (if the Web project is also hosted) is to browse it by
URL. For example http://localhost:1337/Web/Resources/images/event-images/doge.png
OP's Solution : I have done the way which #Pap mentioned.That is :
You should have all your images in the "event-images" folder in your
API project and then have a method to access them(in the API project,
should be part of your API).
My web application project has an App_Code folder. I want to use the methods in these classes from my aspx.cs pages.
There are some classes in the App_Code folder I can access, and some I can't.
I can't spot any differences between them. For instance, all classes have the Build Action property set to Compile.
Is there anything else I should be doing to ensure I can call the classes in the App_Code folder?
With Web Application Projects, you shouldn't be adding App_Code folder. It is intended for Website Projects. With Web Application projects, all your class files are anyways compiled.
The same result can be achieved by creating any folder (MyCodeFiles) and having all the class files inside it. That is why there is no option to create an App_Code option in the VS menu.
If it works, can you try adding a custom folder and see if it has any issues?
If you still need the App_Code to be there, then try checking the namespaces of the files & the build action again.
I'm having a "tiny" issue with my App_Code folders.
I'm learning ASP.NET and, therefore, ordered a webserver with the support of ASP.NET 4.0. I'm using Visual Web Developer to program my webpages. When I upload my website to this webserver everything runs fine.
However, if I then add another web project to my server, my App_Code folder gets all messy. The server wants all my class files in the App_Code folder in the root. Is there any way I can create subdirectories in my App_Code folder or something to keep my projects organized or am I missing the point here?
You should take a look at codeSubDirectories in the web.config
Alright I found a solution to my problem. Although most of your answers might work aswell, this proved to be the best in my case. I created a subdomain and threw all files into that folder and it worked fine.
You should try to avoid using the App_Code folder for your own stuff, especially if you're using a web application project.
Whenever you convert a website to a web application project, the process actually renames your existing App_Code directory to Old_App_Code.
See Here, even though this is specific to converting .net 2.0 apps, I believe it still holds true in 4.0 since converting a 4.0 app does the same thing.:
VERY, VERY IMPORTANT: Because ASP.NET 2.0 tries to dynamically compile any classes it finds under the /App_Code directory of an application at runtime, you explictly DO NOT want to store classes that you compile as part of your VS 2005 Web Application Project under an "app_code" folder. If you do this, then the class will get compiled twice -- once as part of the VS 2005 Web Application Project assembly, and then again at runtime by ASP.NET. The result will most likely be a "could not load type" runtime exception -- caused because you have duplicate type names in your application. Instead, you should store your class files in any other directory of your project other than one named "app_code". This will be handled automatically by the "Convert to Web Applicaiton" command. This command will rename the folder Old_App_Code.
If you have access to a hosting control panel it's probably best to configure your hosting environment with a virtual folder for your second website and run it from the sub folder, e.g. www.example.com/project-b. The first site can still be running in the root folder, e.g. www.example.com.
So both sites will essentially be isolated from each other (just like they are now isolated as two separate projects in Visual Web Developer Express). And both sites have their own App_Code folder (and web.config file).
If you don't have access to a configuration panel, most hosting providers are willing to add a virtual folder for you, since it's really not a special requirement.
The virtual folder should show up as a regular folder in your FTP folder, usually inside the www or wwwroot folder. Now you can copy your project files into that folder.
Take care to use root-relative paths for URLs in your second project, so all links will work even when the website is run from the subfolder. Root-relative URLs look like this:
<asp:HyperLink runat="server" NavigateUrl="~/Default.aspx" />
<asp:Image runat="server" NavigateUrl="~/images/logo.png" />
This will automatically go to www.example.com/project-b/Default.aspx and www.example.com/project-b/images/logo.png when the website is deployed in the virtual folder.
If you need to re-use code from one site in the other, it's typically best to move such code into a separate Class Library project type, and then add a reference to that project to each website project (right-click the website project, choose Add reference..., then select the Projects tab and select the Class Library project).
I am running a CMS as an ASP.NET WebApplication and want to automatically include all files generated by the CMS in the project folder to be included in the project.
By default they are excluded, and finding them by hand and including them every time a new file is created is annoying.
Is it possible to include new files in the web application folder by default?
Web Site Projects work that way, however I am not sure why you would want CMS generated content in your source code repository.
