I recently downloaded and tested your samples, following instructions.

I have set up the databases, when I run the sample I get an error:

Active Session is required for the operation. Use Session.Open()

The idea of samples is they will work out of the box and help developers learn quickly, if we have to debug samples to make them work, then I begin to suspect the product itself.

My environment: Windows 7 64-bit / SQL Server 2008 R2 / Visual Studio 2010 Ultimate / DataObjects .NET 4.5

Honestly, I was using EntitySpaces 2009 successfully. I wanted to switch to a ORM like DataObjects after considering NHibernate for my next project. But if the learning proves too steep, I will be forced to skip.

Please respond to this post quickly...

One Answer:

I would like to retract this post.

Now, all of the samples are working. There was an issue with database connections, which I have resolved after going through documentation.

The ASP .NET sample was not working with the development server mode, it has been documented that it will not work; Once I switched to IIS 7, it threw a connection issue and then I was able to resolve it instantly.

To all newbies (like me) : please take some time to go through DO40 Manual to get a grasp of the of the product, it will help in quickly getting started!

Actually, you're absolutely right - we must simplify this part of post-installation configuration. Precisely, it should be ~ fully automatic.

Personally I hate to tune up something after installation is completed. Why they ship the installer then? Tuning up something after the installation is like seeing you must manually install wheels to the new car you just bought.

So we'll definitely fix this shortly.
