c# - Why is XmlSerializer.Deserialize throwing a System.IO.FileLoadException? -

I have a problem with XML deserialization which is bothering me.

I have an application that supports local customization of various services which it uses, I have implemented an intangible ServiceLocator class whose method returns various objects to each custom The establishment is responsible for implementing a subclass of this and providing the implementation of those methods. The meat of this class looks like this:

  Public Intangible Class ServiceLocator {Public Static Zero Start (String Custom FeaturePath) {Assembly A = Assembly.load (CustomFirePath); Type t = a.GetExportedTypes () .fenamable (). Where (x = & gt; x.IsSubclassOf) (first (); default = (service provider) a.CreateInstance (t.FullName);} Public Fixed Service Planner Default {get; Private set;} Public abstract Create Default Value Container Default Values ​​Container ();}  

It just works fine: I get the custom features assembly path from the custom configuration file, the program call Initialize < / Code>, and then the application can call ServiceLocator.Defaul Different methods on t and they return the appropriate custom implementation of the services.

One of these services is DefaultValuesContainer . This is a simple object that exposes properties The values ​​that are required to retain in the user settings file are considered. I think that I can sort this object in a single user setting type string . This user creates the setting for the file is Which you do not want to edit manually, but I'm good with it.

Here is a concrete implementation of ServiceLocator.CreateDefaultValuesContainer :

 < Code> Protected Override Build Default Volume Container Default Value Container (String Serialxaxel) {DefaultVolume Container C = New ClientDefault Value Container (); If (string.IsNullOrEmpty (serializedXml)) {return c; } XmlSerializer x = new XmlSerializer (c.GetType ()); Return (DefaultVolume Container) xDesign (New StringRedded XML); }  

Now this is the point.

I have created unit tests for this, using NUnit. When I run tests in the test stability class who practice classic custom features, they work. When I run the entire trial suite, the last line of the above method throws the exception:

  System. Resident Operation Exception: There is an error in the XML document (0, 0). ---- & gt; System.IO.FileLoadException: The file or assembly could not be loaded 'ClientCustomFeatures, version = 1.0.0.0, culture = neutral, publicK-token = faucet' or an invalid indicator from its dependency (exception from HRESULT: 0x80004003 (E_POINTER )) ---- & gt; System.ArgumentNullException: The value can not be empty Name of the parameter: path1  

How am I stunned as the set up method still runs, and < Code> ServiceLocator.Default still returns an object type ClientServiceLocator , which means that it has loaded the client controlfoture assembly really, the exception is a lot The only way in the assembly that I am being told is not being loaded.

XmlSerializer Trying to do it here? Is it trying to load an assembly which is already loading? What does "invalid indicator" mean on earth? And above all, how should I do some debugging like this?
