Error CS0433

Hi,

I have an ASP.NET 2 web application (not web site) project and am using a
web deployment project to deploy to the testing, then the production server.
All has been working well for months now, but today after a recompilation,
the app is throwing the error below when accessing a certain page, although
there are no errors in the compilation process.

Compilation Error

A quick Google search revealed quite a few possibilities for fixing this,
such as clearing out the temporary files folder, running iisreset, rebooting
the development machine, rebooting the server, adding batch="false" to
web.config, etc.

I tried all of the above and more, but to no avail.

Has anyone else had any experience of this and, if so, is there a solution?

Any assistance gratefully received.

Mark,

Have you checked that you don't actually have 'iss_proposal'
defined in more han one place in your code ?

That would be a reason for the attempt to compile it into two different DLLs:
intranet.DLL and intranet_deploy .DLL.

That was the first thing I checked. :-)

iis_proposal was merely an example - there have been many other similar
errors all with different classes...

DLLs:
intranet.DLL and intranet_deploy .DLL.
I fully agree, but that's not actually the case....

Additional suggestions :

1.
Could you possibly have two code-behind files with the same name ?
( in different directories, of course... )

2.
Is the server under heavy memory load ?
Maybe testing the app with very little load on the server could make a difference.

Check the commit charge on your server and makew sure the server's ram isn't cramped.

3.
Since you're using the web deployment project, review the MSbuild directives.

i.e., change the number of DLL's the application compiles to.
Maybe, even, reduce it to 1 DLL instead of the, at least, two you have now.

(YourAppDeploym ent Property Pages, Output Assemblies; Merge all output to a single assembly)

4.
Explore one of the other compilation options

re:

If it's "just a test server"...why don't you nuke it ?

Save all your data...and reinstall everything.
That sounds more painful than what it actually is.

This *really* is a bug in WAP / WDP...
And you're not going to believe what it is... :-)

As we all know, one of the changes in the initial release of ASP.NET 2 was
the deprecation of the CodeBehind Page attribute in favour of the CodeFile
Page attribute:
http://msdn2.microsoft.com/en-us/library/wa20t577.aspx

Fair enough. I'm sure lots of us built brand new ASP.NET 2 websites and
created brand new pages from the Project menu and noticed that the aspx page
had the CodeFile attibute instead of the CodeBehind attribute. Whatever...

However, the ASP.NET development community (hello everyone!) threw its arms
up in horror and said "No, we don't like the new project / site model - we
liked the old project / solution model from v1.1 much better, and we'd like
it back please."

So Microsoft, in a rare moment of actually listening to the development
community, said "OK - here you go - Web Application Projects. And we've even
done Web Deployment Projects for you as well, you lucky people!"

So everyone downloaded and installed the new add-ons and smiled a lot for
they were good.

However, if you build a brand new Web Application Project and create a new
form from the Project menu, you'll see that the aspx Page attribute is
CodeBehind again, not CodeFile...

If you then drop a v2 aspx file from a Web Site Project into a Web
Application Project and FORGET to change its page directive from CodeFile
back to CodeBehind...

Seems the new Web Application Project compilation model doesn't support the
CodeFile page attribute properly, and gets its knickers in a right old
twist... Hence, the double class reference...

AAARRRGGGHHH!!!

The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols. I succeeded, with both firewalls in the same network.
