Hallo zusammen,
ich versuche gerade einen ASP.NET Service unter mono zu deployen.
Er besteht aus einer DataLib und dem eigentlichen Service.
In der global.asax habe ich folgenden Code implementiert:
Aktuell habe ich das Problem, dass der MySqlProvider nicht gefunden wird. Ich erhalte nachfolgende Fehlermeldung:
Die MySqlProvider.dll ist im bin Verzeichnis des Webservice hinterlegt. MySql.Data.dll, NDO.dll und NDOInterface.dll im GAC.
Hat evtl. jemand einen Tipp für mich ?
Gruß
Carsten
protected void Application_Start(object sender, EventArgs e)
{
NDO.MySqlProvider.Provider p = new NDO.MySqlProvider.Provider();
NDOProviderFactory.Instance["MySql"] = p;
_pm = new PersistenceManager();
Application.Add("persistenceManager", _pm);
}
Description: Error processing request.

Hi Carsten,
NDO searches Plug-in DLLs either in the base directory of the AppDomain or in a directory, which can be defined in the registry under the key
HKEY_LOCAL_MACHINE\SOFTWARE\HoT - House of Tools Development GmbH\NDO\1.1
The Value is AddInPath and should contain a string to the path, where the plug-ins reside. There is a file UserSetup.msi in the NDO distribution, which creates the directory and writes the registry entry for you. Just copy the MySqlProvider.dll into this directory.
.NET copies all dlls of a web application into a shadow directory and runs the application from there. If you can't use the registry key you might consider to reference the MySqlProvider.dll directly from your web application. This should cause the DLL to be copied to the shadow directory.
If neither of that works, you can put the provider into the provider list with the following code:
NDOProviderFactory.Instance["MySql"] = new NDO.MySqlProvider.Provider();
This requires a reference to the MySqlProvider.dll. You can put this code in the Application_Start event in the global.asax or global.asax.cs file.
If you have further questions, please ask.
RegardsMirko
