After adding one additional model to the solution, I was able to repro the issue.

I'm filing a bug in this regard and will keep you updated on our progress.

 

Regards,

   Silvio.

 

I tested your application and without changing anything I have the issue. I did rebuild the solution 20 times and got 6 times the error. Each time the error was on the Model2, below the stack trace if it can help.

 

Could it be an installation problem since I have both 2010 and 2012RC on my computer ?

Let me know if you want I check something on my system.

We tried to reproduce your issue, but were not able to.

 

I've attached a simple CF sample with 2 models where I was able to compile/run without issues.

Please modify it to repro the issue or provide a sample that demonstrates the problem.

We didn't make any Code First or VS 2012 related changes for the 6.1.7.1 patch release.  The only change from 6.1.7.0 was a fix for a performance problem, so you will still see the VS11 /  VS2012 issues you saw previously.   We should have some additional VS2012 fixes in the 6.1.8 release.

A project having just one model can sometimes build after 1 or 2 retry but when you have a solution with multiple models (my case), there is always some models which doesn't compile. you can try to compile them one by one, it always fail when you hit F5.

 

For DevForce to recognize the ibmmx it has to be set as an Embedded Resource in the project, so that's one thing to check. 

 

The Code First compile problem(s) will occur only in VS11.  You should be able to use CF in VS2010 without problems (or any additional problems than you might have had in prior DevForce releases).

 

When DevForce doesn't (re)generate the ibmmx there can be several reasons -

1) the EntityModelMetadataDeploy task was not run because there's no .cf file, the SkipDevForce build property flag is on, or the task is not installed, or

2) the task runs correctly but thinks the ibmmx file is up-to-date.

 

 

Another thing happening since the uninstall/install

 

I did compile the solution with VS10, it generated the ibmmx file and the application run perfectly.

now it I run the same solution within VS11, it generate an exception during the EntityManager creation.

 

It's like it ignored the ibmmx file ...

 

 

I had many msbuild.exe instance, I killed them all. then I wanted to try but I broke everything.

 

Just before, I did an uninstall of the 6.1.7 and then reinstalled it. Now, if I delete the .ibmmx file, it never generates it and says all is done.

The uninstall broke something which a repair or a new install didn't fix (I tried both).

Any idea where I should look ?

 

We haven't seen this particular error before, but have seen a few other problems with builds in VS11 (see http://drc.ideablade.com/xwiki/bin/view/Documentation/code-first-troubleshooting#HBuilderrorsinVisualStudio11Beta).  I'm guessing that you can still run your application because the prior ibmmx file is still present and unchanged.  If you were to delete the ibmmx and try a build, you'd probably see that the ibmmx is not regenerated.

 

When you close your solution, also check the Windows Task Manager to see that there are no devenv.exe or msbuild.exe instances still running, and close them if so.  Then try the build again.

 

Builds in VS11 are shelled to MsBuild.exe instances, which does cause problems with our Code First build-time support.  We have a command line tool which can also be used to regen an ibmmx, which we may need to ship until we get the CF problems in VS11 worked out.

 

 

 

 

Actually I have this error within Visual Studio every time I try to compile. I closed many time my VS instance, it didn't work a single time.

However, it seems this error doesn't always block the execution of the application.

Exemple :

1. I do a full generate on my solution

  => I am getting this error on every model

2. then I hit F5 and the application start dispite the error

  => note that the errors are still displayed in the error log window

 

Or

 

1. I build the solution

  => I have the errors

2. I build every model one by one to

3. I can start the application

 

 

One annoying things (but probably a VS11 bug) is that if I have some errors in my code, I see those errors in the Error window during the compilation time but when the compilation end they all disapears and only the EntityModelMetadataDeploy's error are left.

This make it very hard to fix the error in the code ....

I am getting this error during the compilation of my CF models in VS11 beta with the last version 6.1.7 of Devforce.

Note :  the message "Le filtre de messages indiquait que l’application était occupée" could be translated to something like  "The message's filter indicated the application was busy"
