Wcf – How to read app.config from a custom location, i.e. from a database in .NET

configurationlocationwcf

I am trying to override the ApplyConfiguration method in my custom ServiceHost to read the configuration from a database instead of app.config. Ideally I would want to be able to do something like this:

Configuration config = GetConfigFromMyDatabase(…);

ServiceModelSectionGroup serviceModel = ServiceModelSectionGroup.GetSectionGroup(config);

Is there any way to do this without writing a temp app.config file?

Best Solution

What about using:

System.Configuration.ConfigurationManager.OpenExeConfiguration(string exePath)

That should let you open an arbitrary app.config file.

C# – the best workaround for the WCF client `using` block issue

Actually, although I blogged (see Luke's answer), I think this is better than my IDisposable wrapper. Typical code:

Service<IOrderService>.Use(orderService=>
{
  orderService.PlaceOrder(request);
});

(edit per comments)

Since Use returns void, the easiest way to handle return values is via a captured variable:

int newOrderId = 0; // need a value for definite assignment
Service<IOrderService>.Use(orderService=>
  {
    newOrderId = orderService.PlaceOrder(request);
  });
Console.WriteLine(newOrderId); // should be updated

.net – Read .NET configuration from database

There's an article here that talks about doing what you are talking about:

http://www.wrox.com/WileyCDA/Section/Redirecting-Configuration-with-a-Custom-Provider.id-291932.html

In summary what they do is create a derived version of ProtectedConfigurationProvider, which is typically used to encrypt .config files. In the Decrypt method, instead of decrypting the configuration information, it's retrieved from a database.
