.NET8.0 XML Exception Problem

[SwEngine]

I was using the package in .net7.0 without problems. However, after updating to .net8.0, my program throws error. When I unchecked the trimming unused code option, there was no error, but it increases output file size very much. How can I solve it?

Hi @SwEngine,

can you please be more specific?
What exact error do you get when you do what?

[SwEngine]

I use only normal logging processes. When releasing the executable, I checked the trimming unused code option, it gives the error below,
However, when I unchecked the trimming unused code option, it does not give any error.

@SwEngine thanks for the info. Can you check whether the change in #143 works for you?

[SwEngine]

I could not build your code :( could you share a dll file? Sorry for inconvenience

[FreeAndNil]

@SwEngine netstandard2.0.zip

[SwEngine]

I am adding your dll file to my project from project references, however

logger = LogManager.GetLogger(typeof(Logger));

this line gives error of:

Severity	Code	Description	Project	File	Line	Suppression State
Error	CS0012	The type 'Assembly' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Private.CoreLib, Version=7.0.0.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e'.	Logger	C:\Users\Desktop\Logger\Logger\Logger.cs	15	N/A

[FreeAndNil]

Can you put a simple repro somewhere on Github?

[FreeAndNil]

@SwEngine maybe posting your csproj file could also help

[FreeAndNil]

@SwEngine is this still relevant for you?
Otherwise I will close this at the end of the week.

[SwEngine]

I am on vacation, but next week I will look at again, thank you so much!

[FreeAndNil]

@SwEngine could you take a look?

[FreeAndNil]

@SwEngine please reopen when you have feedback

[szogun1987]

I have the same error in relatively simple project.
Error does not occur on dev environment.
Error occurs in the docker image.
I use Microsoft.Extensions.Logging.Log4Net.AspNetCore to integrate log4net and my app. It handles only log4net.config so it can be a problem.
I prefer not to keep project private (I'm not sure if repo contains some auth data) but I can share it with 1 or 2 persons (on Gitlab)

Edit:
Here is a link to the same issue in integration library: huorswords/Microsoft.Extensions.Logging.Log4Net.AspNetCore#138
