Use class ... why is not available?

[shapper]

Hello,

I am working with VS 2008 and created a Web Application Project.

I added a class but whatever I do the class is not visible to my aspx
pages or anywhere else.

I then changed the property Build Action in my class from Content to
Compile. Now it is recognized.

Why do I need to do this?

Do I need to do this with all classes I create?

Thanks,

Miguel

Sounds like something's up with your installation of VS.NET, as classes
(should) have their Build Action property set to Compile by default...

Hi,

I think the problem is where the classes are being added to.
App_Folder or somewhere else.

I created a Web Application Project.

When I add a class to App_Folder it VS 2008 makes "Build: Content". If
I add the class somewhere else it says "Build: Compile".

The problem is when I create classes in App_Folder they don't seem to
be accessible to ASPX pages as it is usual in Web Site.

When I changed them "Build: Compile" then I am able to build the
solution with no errors but when I preview an ASPX pages I get errors
everywhere.

The only solution I found was to make all classes "Build: Compile" and
rename the App_Code folder to New_App_Code.

I think I am missing something.

Any idea?

Thanks,

Miguel

Have you tried putting all your classes in the App_Code folder, instead of in your App_Folder folder ?

ASP.NET will not automatically compile classes in application folders,
but *will* compile classes in source files in the App_Code folder.

Better yet, have you considered compiling your helper classes
into assemblies and placing the dll's in your app's bin directory ?

Sorry, when I wrote App_Folder I meant App_Code ... and that is the
strange problem!

Thanks,
Miguel

I am pretty sure that classes in the App_Code folder don't work in a Web
Application Project as you would expect them to in a Web Site project. Put
them next to the aspx pages and they'll get compiled.

re:

AFAIK :

By default, only class files of Web application projects are compiled
by MSBuild when the Build Action property is set to Compile.

However, if a Web Application project includes class files in the App_Code folder,
those class files will be compiled by the ASP.NET compiler.

This is true even if their build action is not explicitly set to Compile.

The App_Code folder exists for Web site projects.

This folder is not included in Web Application projects by default,
although it may be explicitly created and any class files placed in it *will* be compiled.

I am having the same problem but with Web Applications on VS 2005. Now
I know about the problem it is more of an inconvenience than a problem
for us. I was hoping that this problem would go away when we migrate
to VS 2008 later this month.

Also, Crystal Reports files (rpt) need their type set to content
otherwise the installer does not copy them for installation. Again,
more of an inconvenience than a problem.

Cheers,
Mark
