Support for Azure Functions
ChristopherL-STCU opened this issue · 18 comments
When I try using this in an Azure Function I receive the error:
System.Private.CoreLib: Exception while executing function: MyTestClass. ExtendedXmlSerializer: Unable to load DLL 'fusion.dll' or one of its dependencies: The specified module could not be found. (0x8007007E).
Here's my sample code:
var serializer = new ConfigurationContainer()
.EnableImplicitTyping(typeof(MyTestClass))
.Create();
serializer.Serialize(new MyTestClass { MyProperty = 1 })
public class MyTestClass
{
public int MyProperty { get; set; }
}
Is it possible for me to configure ExtendedXmlSerializer to be used with Azure Functions or is it possible for the library to be updated to be usable in an Azure Function?
Hey there @ChristopherL-STCU thank you for writing in with this question. I am glad to see that I am not the only one with struggles around Azure Functions. 😁 In fact, I encountered them so much I ended up using WebJobs as much as I could in its stead.
In any case, are you able to confirm if this occurs if you remove all ExtendedXmlSerializer code? If so, I would start putting Information outputs (logging) around the lines to see where exactly this is failing. I am unaware of what fusion.dll is, but apparently, it has some history with this error.
Thanks @Mike-E-angelo. The error only occurs when I add ExtendedXmlSerializer. I noticed the GitHub issue you referenced when I was trying to figure it out as well. I also see fusion.dll is used by ExtendedXmlSerializer. I wonder if fusion.dll is not available from within the Azure Function context. Azure Functions are particular. I don't know much about fusion.dll either and so I don't know if this should work within an Azure Function or if a different approach is needed for Azure Functions. It may not be worthwhile to try to figure all of this out, but I thought I'd ask the question here.
Branch issues/fix/i543 created!
WOW... first off, thank you for having more interest in this area than I do, @ChristopherL-STCU. 😆 I appreciate you digging through and finding the culprit. I was pretty amazed that we indeed had a dependency on this dll, and even more amazed that it somehow works cross-platform.
I believe that was added eons ago before there was a netstandard2.0 call to Assembly.Load/LoadWithPartialName.
I have updated the usage of this, and a build is here for you to check out:

Please let me know if you run into any further issues and I will take a look into it for you. 👍
Doh I may have mispoken here, @ChristopherL-STCU ... the logic appears to be related to #366 and is intended to retrieve from the GAC.
Can you confirm that you are using Azure Functions in .NETCore or .NET Framework? And which version?
Hi @ChristopherL-STCU if you are using .NET Core please try this build out:
#544 (comment)
If you are running .NET Framework then I am out of ideas. That fusion.dll is a very native assembly and should be located for .NET Framework scenarios. I cannot remove it as it is necessary for scenarios such as #366 where the GAC has an assembly that is not found on local disk. As such, I have basically modified the build so that the GAC-accessing logic is only emitted for the .NET Framework libraries. Hopefully that addresses the issue here, but who knows with Azure Functions. 😓
Wow! Thanks for making the change so quickly!
It is using .Net Core, <TargetFramework>netcoreapp3.1</TargetFramework>. I grabbed the preview version you just built but I'm still experiencing the error. 😕 I decompiled the assembly and I do have the change you made. I'm not sure what's up. I'll continue to experiment and report back if I make any progress.
Whoa so you are saying you can verify that the link to fusion.dll is removed and you're still getting a fusion.dll error? That is wild. It must be a caching issue. Does this occur locally or deployed?
The problem appears to be because there is a hyphen in my project name, and so there is a hyphen in the generated assembly name. The ExtendedXmlSerializer assembly parser does not include hyphen as a valid character when parsing the assembly name. This mean when ExtendedXmlSerializer tries to load the assembly it's only using a partial name of the assemble, and therefore cannot find it. This causes ExtendedXmlSerializer to fallback to the old assembly load method which uses fusion.dll, hence the error message I'm experiencing.
Excellent work in tracking this down, @ChristopherL-STCU. I am going to undo the work yesterday as I absolutely detest compiler definitions which is what I was using to make that work.
(That stated if we still need to do this for whatever reason I can re-introduce it)
Please try this build which allows hyphens as allowed characters in assembly names and let me know if it treats you any better:
#544 (comment)
Yes, that works for me! 🎉 Thanks! ❤️
Awesome! Release days are typically on Tuesdays so I will get this launched out next Tuesday. Please feel free to use the preview build until then and I will update here once it's deployed to NuGet. 👍
This has been deployed to NuGet:
https://www.nuget.org/packages/ExtendedXmlSerializer/
Please do let me know if you encounter any additional/further issues and I will look into them for you.
Closing this for now.
An extensible Xml Serializer for .NET that builds on the functionality of the classic XmlSerializer with a powerful and robust extension model.
Hey there! I'm having the same issue with .NET 5 and EXS 3.7.5 🤔

Doh sorry to hear this @SuperJMN and thank you for reporting it. Can you say if this is something new for your codebase? That is, did it work with a previous version of ExtendedXmlSerializer?
No problem!
It's a new codebase (new project). I could test anything you may need. The serializer is created like this, just in case it's useful:
NOTE: 3.7.4 doesn't work, either.
I may have to fallback to LoadWithPartialName. Just for kicks @SuperJMN, are you able to try out this build?
It has LoadWithPartialName for non-.NETFramework builds.
Ouch. I've tried every package in that thread, but no dice.
