Support configuration reading from XML file that is not app.config

What steps will reproduce the problem? 1. Call ctor of ConfigurationSettingsReader
2. Pass custom xml file (see below) as file paramter
3. Autofac complains that it cannot find the section

I would like to see a SettingsReader that can read custom XML (just a plain vanilla autofac section, no app.config specific schema) to configure autofac. What version of Autofac are you using? On what version of .NET/Silverlight? .NET 4.0, version 2.6.3.862

I suggest providing an XmlSettingsReader that does not look for a specific section, but just reads the entire file into a SectionHandler. Given some restrictive accessors (internal types, private _sectionHandler field on ConfigurationSettingsReader) it's tough for me to do this in my own project/namespace (I need to use vanilla autofac binaries for various reasons).
I tried to derive from ConfigurationSettingsReader, it seems if I managed to deserialize the SectionHandler (tricky since ConfigurationManager is coupled to app.config...) and assign the _sectionHandler via reflection. My main issues were the deserialization part. It's probably much easier for you guys.

the schema of the file I'd like to load contians only autofac info, nothing with regards to app.config (i.e. no root, and no )

// autofac.config


...

If I find some down time I'll see if I can do it myself and submit a patch, but it would be great if you guys could do this.

Thanks for the excellent tool!

Sorry, this should be an enhancement, not a defect

I have something for this working in the 3.0 code. As soon as I push it to trunk, I'll update this issue as fixed.

The new class to look for is XmlFileReader.

builder.RegisterModule(new XmlFileReader("path/to/config.xml"));

It uses the same XML schema as the regular configuration settings but doesn't require the stuff that standard .NET configuration requires.

Pushed to trunk. When 3.0 releases, you'll see the new bits.

Status: Fixed

I know it's been ages, but this seems to be working, so thanks :-)

Is the XMLFileReader class been depreciated? I can't seem to find it any longer.

Read the docs.

Ok so you want this now?

builder.RegisterModule(new ConfigurationModule(new ConfigurationBuilder()
.AddXmlFile(Path.Combine(BinaryPath, $"{ApplicationName}.config"))
.Build()));
