ASP.NET 2.0: Global.asax code-behind and web deployment project problem

[Hardy Wang]

Hi all,
In order to solve code-behind of global.asax problem, I removed the code
from global.asax, and just leave one line "<%@ Application Language="C#"
Inherits="Global"%>" in this file. Then I created a CS file in App_Code
folder named Global.asax.cs:

public class Global : System.Web.HttpApplication {
void Application_OnError(object sender, EventArgs e) {
// my own complex error handling logic
}
}

When I debug locally, it can jump into this function whenever some error
happens.

Then I added a Web Deployment Project to my solution, and merged all DLLs
into one, I copied all my files to web server. BUT when I run the web
server, I got following error

Compiler Error Message: CS0433: The type 'ASP.global_asax' exists in both
'c:\WINNT\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET
Files\root\0059d51c\80906b1d\App_global.asax.gyayxcqz.dll' and
'c:\WINNT\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET
Files\root\0059d51c\80906b1d\assembly\dl3\3e64f089\c486205e_fcd1c601\MyWebProject.DLL'

It seems that Web Deployment Project compiles global.asax as well, so that
there are 2 classes named "Global" existing in assemblies.

Who knows what is the solution to solve this problem? I cleared all
temporary files, it doesn't help at all.

I am mad.....

Hello Hardy,

From your description, I understand you're using the VS 2005 "Web
Deployment Project" add-on project to precompile an ASP.NET 2.0
application. However after the compilation and try running the precompiled
the application, you're getting type loading error against the
global.asax's codebehind class, correct?

As for this issue, based on my experience, it is related to the how the web
application is precompiled (through webdeployment project or not). Have
you configured the precompiled site to be updatable or have you configured
the web deployment project to precompile the application into multiple
assemblies?

As for the global.asax file, based on my local test, if you use "web
deployment project" to precompile the web site, the output compiled
application directory will not include the "global.asax" file in it, this
is because the global.asax is only needed by the ASP.NET runtime and after
precompilation, there will output an "App_global.asax.compiled" file in the
"bin" directory which identify the assembly which contains the class to
serve the request to global.asax. (see below)

=====================
<?xml version="1.0" encoding="utf-8"?>
<preserve resultType="8" virtualPath="/DeployWebApp/global.asax"
hash="f424386" filehash="fffff5d6110aa691" flags="150000"
assembly="DeployWebApp_deploy" type="ASP.global_asax">
<filedeps>
<filedep name="/DeployWebApp/global.asax" />
</filedeps>
</preserve>
=====================

Therefore, there should not exist "global.asax" file in the precompiled
output application's directory. Is this the case in your scenario?

Please feel free to let me know if there is anything unclear or if you have
different settings as I mentioned.

Thanks for your reply Hardy,

Yes, the ASP.NET 2.0 percompilation has many particular settings. And those
generated files like the xxxx.precompiled is necessary , so you need to
copy them together with other assemblies in "bin" directory.

Anyway, I'm glad the suggestion has been helpful. If you need any further
help, please feel free to let me know.

Sorry, my mistake. It still doesn't work.

I try to run a fake ASPX page to trigger an (404) error to let Global.asax
to capture, it worked.

When I loaded my normal ASPX page, I had same error again.

Thanks for your followup Hardy,

I'm sorry to hear that the problem remains. In order to get a clear view,
is it convenient that you create a simplified project with global.asax and
some simple pages which can reproduct the error? If so, I can perform some
local test agaist them. You can touch me through the email in my
signature(by remove "online").
