I am getting these errors when deploying my web applciation (VS.NET 2.0) to Win2003 SP2, iis6.0.
- The directory "WebAppName/App_WebReferences" is not allowed because the application is precompiled.
If I delete the App_WebReferences folder, the next error is The directory.../App_Code.... is precompiled.

After searching around on EE I found a thread (below) that mostly described some options to try by I'm not clear on the specific steps.
Here's what is happening:
1. Right-click the web app and select BUILD WebSite
2. Copy the folder containing the web application and all its contents to the web server where it will be deployed (this is a "test" environment).
3. Run the web app:  http://..../default.aspx
4. I receive these errors
The directory "WebAppName/App_WebReferences" is not allowed because the application is precompiled.
And If I delete that folder...
The directory "WebAppName/App_Code" is not allowed because the application is precompiled.

5. The thread from EE says to build the application differently follow these steps:
How to change the project to Uncompiled:

    1. Go to your project properties page
    2. Select the Build Option
    3. In the "Before running startup page" select the option "No Build"
    4. In the "Build Solution action" uncheck the option "Build Web Site as part of solution"

After deploying this to the web server (copy the folder and its contents) This to results in an error, indicating that there are duplicate code files:
Compiler Error Message: CS0433: The type 'Helper' exists in both 'c:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\webappname\dbb281d9\f91cd8bd\assembly\dl3\fcb3412e\7d20a5ef_0cc0c801\App_Code.DLL' and 'c:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\webappname\dbb281d9\f91cd8bd\App_Code.d1dlmug8.dll'

6. I deleted App_Code folder from the deployed location.  The application works as expected.
Note: when I deployed the Compiled version of the web application, I deleted two items: the App_code folder and the  PrecompiledApp.config.  Once I did this the app performed as expected.

That's a long way to get to my queston.  What is the best practice for building and deploying web applications that present these kinds of issues?  Is there a Step-by-step anywhere?

Thanks in advance for any assistance.
Paul

Don't copy the folder. Use "publish website". That will correctly upload only the directories that need to be uploaded.

Vadimrapp1,

Thanks.  My fault, I should have mentioned that these are on different networks.  I've no way to use publish website to get the web application deployed to the test site.

Alternative?

Thanks,
Paul

add setup and deployment project to the solution; add output from the main project; build setup, then run it at the target site.

another way: publish website to your local server (or any server you can publish to), then copy from there.
