We have an entity with a composite key of the following values:
key1 = 44
key2 = 1
key3 = “published”

We are trying to serialize the Entity to XML where the GetHashCode() method is called and generates a huge number wich is obviously beyond the int limit. This is where execution enters the following while loop of the GetHashCode() method which it never exits..

while ( int.TryParse(hashstring, out hashcode) == false )
hashcode = hashcode / 11;

Are there any suggestions?

I am still reading this blog. I am currently writing an VB.Net WinForms application based on your example (users, departments). As soon as I have finished this little demo project, I will zip you the whole project.

Best regards,

You can get the source code two ways:

1. Using a Subversion client, or
2. By going to the releases page at http://www.hosted-projects.com/trac/computersims/wilsonorwrapper/wiki/Releases and clicking on a release to download. I just added a source code release on this page.

And @marcel — if you’re still reading — I have successfully used this with MySQL. In fact, I used the exact same code against schematically-identical MySQL and MSSQL database — a very nice thing indeed.

Since I’m working on this, I’ll work up an example application demonstrating how to configure your framework generated objects with the ObjectDataSource control and the radGrid control developed by Microsoft. Based on my pervious experience, I think I may have a few suggestions for you on modifications you may want to make in your codebase (and corresponding codesmith templates).

When I have something … I’ll send it your way.

Are you using a licensed version of the O/R mapper or a demo version? The demo version will give a license error when running outside Visual Studio, which means it’ll give an error when running in NUnit. Note that the O/R mapper DLL in the references folder is the demo version (for obvious reasons).

Glad to hear you are having no problems otherwise! I’ll look into the unit tests to see if there’s a lingering issue.

Sorry that the templates are C# only — if someone wants to convert them to VB.Net I’ll add them to the distribution.

Everything is ok, I could run the NUnit Tests also with my MySQL Database.
If I use the “tests.nunit” for starting the NUint FrontEnd I get the error I described.

If I open the NUnit Frontend and if I select the UserAppTests.dll manually
then it works perfectly!
So, don´t spend your time for checking if your framework works with MySql, it works!

I have also started to write this evening a simple Console Application (entity classes
have been generated in C#) in VB.Net , and everything I tried worked perfectly, inclusive transactions!
