Any Ideas ?

I assume you use VB.NET? (as it happens with VB.NET a lot) and you get this during compile?

If it is at runtime, do you reference the dll's from a network share?

No, I am using C#. It happens after I compile and try to run under debugger. The last time it happened it was followed by ASP.NET crashing and a restart of IIS after which it ran through fine.

No network share. I added refernences to the two SD assemblies and properties shows copy local = true. I put a copy of the license in the same (bin) directory in case that was it but no effect.

This is driving me nuts. More info for you.

I am using impersonation thru to SQL server and am setting the access on each Table as appropriate.

I am using Intergrated Security.

Hope this helps..

Regards

More info ..

I am running under a transaction which is now standing at 6 rows in different tables and will grow. The transaction is similar to the one in your documentation. I am not sure if you are using your own tp model or ADO's but it is not COM+.

Regards

P.S. Will try without debug after my next edit

Without debug, same problem occurs..

OK, I thought you were refering to an error you got when you were compiling the code.

So you run the code and you get a security exception, could you please paste teh complete exception here, including the stacktrace? thanks.

Sorry took so long, this machine is isolated from my dev network.

This tells me the save action tries to update a table but the current user (probably the ASPNET user) is not allowed to update / insert a row in the table ACCOUNT.

Could you check for that for me, please?

(btw, you can fix the casing of the entities by setting the CorrectNameCasing preference in the preferences to true (before a project is created) or if you have already a project, change it in the project properties and the entities added after that will be properly cased (and f.e. without '_')

The public user has the rights needed to do this and the ASP.NET user has been assigned the public role.I did check the database itself and granted some privileges to the public user, specifically create table, view, sp, ... I will check and see if this makes any difference.

For testing, could you please add the ASPNET user to the db_owner role and see if it works then.

It made no difference, it worked fine, I made a change to the code, recompiled and error is back. The ACCOUNTEntity is the first row saved and I believe that is why the error occurs there. I can change the code around and verify.

Our messages crossed. I added the ASP.NET user to the db_owner role and the same error occurs.

What is consistent is that on the first time thru after a build, the error occurs. On the second time thru, no problem ...

Beginning to hear a little Twilight zone music here ...

By the way, thanks for the attention. This is impressive ..

Hmmm... Really weird. What I previously said about the actual query rights is not correct, it seems the SqlServer DQE dll isn't accessable and that throws an exception. Has the ASPNET user read-rights on that dll in the bin dir? (I'm guessing here, but with this kind of errors, everything is possible )

Yes, the rights are read and execute. The default NETWORK_SERVICE account did not have execute so I gave it, but no effect. The rights on the internet user are fine.

Unfortunately, I have to go, but will be back later.

Thanks again for the hep.

This is too weird. Three time ASP.net has crashed, loads of warnings in the System logs about application pools being killed.

I am going to uninstall IIS, ASP.NET and reisntall and see what happens

Re-installed IIS and ASP.NET, rebuilt the LLBLGen project, rebuilt the test program and the problem has not re-occurred since, 10 tries.

No changes to SQL Server, accounts or tables.

Have not got a clue why this worked.

The ASP.NET crashes turned out to be the Application Pool rapid-fail-check shut down the pool after 5 failures in five minutes. There was only one pool defined. A debug session seems to count as a failure. I reset these values to more realistic values and none of the problems occur any more.

Sorry to have wasted your time, but thanks for the effort, I hope this is over?

Regards

Weird issue... I hope this is indeed gone now If you run into it again, let me know

Frans,

I'm lucky enough to be experiencing the same problem. I have a runtime error that I'm trying to debug and it's throwing an exception.

When I first run my application in debug mode I am prompted to enter user cradentials to initiate a debug session. The app then runs along happily until it crashes.

The next time I run the application I'm not prompted to enter user cradentials for the debug session. I assume that these persist until you exit .NET or log off. Don't know which.

The error I'm seeing ("Unable to load reference library" and "Access is denied") leads me to think that the sd.llblgen.pro.ormsupportclasses.net11.dll isn't being released after the crash. The debug session still has control.

I can start and stop the application as many times as I want, recompile, change code, it doesn't matter.

In my case, if I shut down the .NET Dev Environment, open it again, and then reopen the solution I'm able to run the application, to its crashing point, one more time before the "Access is Denied" error re-occurs.

I don't know if this is a .NET debugging issue or an issue with the DLL's?

As with Sink, I'm using impersonation. However, this application is the first "impersonation" type web application that I've been prompted to enter user cradentials to debug. I believe If I can figure out how to eliminate that, the problem will go away.

Sinks solution seems to buy time but I don't think it answers why the dll isn't being freed after the crash.

The real question is why doesn't the debug session release the dll? or what is the proper way to close a debug session when a fatal error occurs?

What are your thoughts?

Paul

I could find a lot of people on Google groups with the same error. It's not related to the dll's but to ASP.NET

1 (one) Microsoft employee tried to help in all those threads (and if amount of support is this low from them, you know there is a bug in the framework somewhere). He pointed to: http://support.microsoft.com/?id=324519

A weird article, as it says that signed assemblies are not supported in the bin directory. Huh? This site has them in the bin directory, never had a problem.

Apparently the dll's are locked by a process. This might be the asp.net worker process, I don't know. What you could do is download process viewer from www.sysinternals.com, and check, AFTER you've received this error, which process holds the dll which can't be loaded.

I'm not sure how you start debugging processes in ASP.NET, just by hitting F5 I guess. If the debugger crashes or breaks, stop the debugger from the IDE, and wait till the debug process is completely stopped in the IDE before restarting. But I don't have a clear answer to this other than that it's not something inside the dll's.

Sure pass it off on the other guy! Now we are getting the kind of support we are used to!

Thanks for the information and tips.

I have never had an issues either... thats crazy jeez..

MS = "Strong assemblies are good, sign your stuff, but o yeah you can put them in the BIN directory"

thats crap

anyhow

I had some issues a few months ago with some web apps. Don't know if they are related but figured I would throw it out there. Every once in a while I will get access denied messages. After much research (sorry cant find the links) I did the following and I haven't had any issues since

1. I had antivirus running on the web server, I excluded the c:\WINNT\microsoft.net\ directory,the bin directory and the root of the web site (web.config)

2. Made sure authenticated users had Read Write and list folder contents to the c:\WINNT\microsoft.net\ directory and below

I think what was happening was that the antivirus would touch something in the web directory that would cause the application to restart. IF a user that hit the website after the restart didn't have permission to the c:\WINNT\microsoft.net\ directory an error would be thrown. I am running using windows authentication but in your case I would make sure what ever process that is running the web service has access to the c:\WINNT\microsoft.net directory hope this helps Bert

Good tips, Bert That can be an issue as well indeed.

Paul: I'm sorry But! because you're a Microsoft customer, you could try calling PSS and ask them to fix this. You'll never know if there is already a 'hotfix' for this (and you all are not alone in this, the error is common, so perhaps another one has mailed/called them already)
