I am thinking of use IDataSourceKeyResolver for dynamic Connection strings handling.
I got test solution from here:
http://drc.ideablade.com/xwiki/bin/view/Documentation/code-sample-custom-datasourcekeyresolver
but it does not work.
I have the following situation:
* ServerModelTomato.Tomato entity have attribute:
[IbEm.DataSourceKeyName(@"Tomato")]
* Console01. Program execute this:
var entityManager = new DomainModelEntityManager(true, "Customer01");
foreach (var tomato in entityManager.Tomatoes) {
Console.WriteLine("Tomato {0}", tomato.Variety);
}
* During first call to entityManager.Tomatoes, CustomDataSourceKeyResolver.GetKey method invoked
and proper 'Tomato_Customer01' ClientEdmKey generated along with proper connection string.
* Then the error raised:
The connection string for Key 'Tomato_Customer01' was not found or is invalid. Check that either a connectionStrings element or EdmKey is defined for this key in the configuration file, or implement a custom IDataSourceKeyResolver.
It seems that dynamically created ClientEdmKey was ignored or lost somewhere.
Is this a bug or I have missed something?

Did you unzip and install the databases in the data subfolder? My guess is that the GetConnectionString logic is failing because it can't access the tenant database, as the sample works fine for me.

[Solved]
I forgot to try common trick against strange application behavior.
After computer reboot, application works as expected.
