configuration error

scottrm

We have two developers, call them A and B, (on Windows XP) developing a
number of asp.net web sites on a shared server (Windows 2003). Everything has
been ok but recently for no apparent reason whenever developer A builds a
particular project (which builds with no errors) and then tries to access the
web site they just built they get the error below. Other projects built by
the developer A are ok and also if the other developer, developer B, builds
the same project the web site runs ok.

Here are a couple of recommendations:
1) Developers should be developing/debugging locally and deploying to
Dev/QA/Prod servers and not developing directly against them.
2) Are Dev A and Dev B using the same build configuration when they build?
I had one member of my team decide to create his own config that excluded App
Blocks from the build (we're using project references) and he ran into the
same issue.
3) Are your devs referencing the Data Block assembly or project reference?
4) Typically you'll have a build manager or build machine that pulls the
latest tested code out of source safe, perform a build, and then deploy to
your target server.

Thanks for JPSklenka's informative inputs.

Hi Scott,

In addition to JPSklenka's suggestions. Here are some of my suggestion:

From the error info you provided, the ACCESS DENIED error seems caused by
the DataAccess Application Block's assembly can't be correctly load. I
think the project (with error) must have referenced the DAAB's assembly ,
yes? And is the DAAB assembly referenced in your project a strong-named
version? If so, have you put it in the server's GAC or just directly use it
in the web project's private bin path? There is a known issue that
strongnamed assembly must be put in GAC when used in asp.net web
application. Please have a check , if there are any other new findings
,please feel free to post here.

Thanks.

Thanks for your reply.

In response to JP Sklenka dev a and b are using the same build configuration
and neither of them changed anything before the problems occurred. We are
referencing by project but that has worked fine before as did working on a
shared server.

I don't think the error is specific to the data access application block
because previously I got the same error with a different assembly which I
removed because it was no longer in use, but as soon as I removed it I got
the same error with the DAAB so I guess none of the assemblies could be
loaded.

Bizzarely the problem seems to have fixed itself without any changes or even
a reboot. I would still be interested to know if you have any more ideas in
case it happens again.

Hi Scott,

Thanks for your response. If the problems went away without doing anything,
I'm afraid it must still exists, but not occur currently. The DAAB I
mentioned in the last message just means strong-named assembly , if there
are any strong-named assemblies used in your asp.net project and are put in
the private bin path, please move them to the GAC , that sometimes will
cause such unexpected problems.

Thanks.
