log4net:ERROR Could not create Appender [HttpAppender] of type [Log4net.HttpAppender.AsyncBatchHttpAppender, Log4net.HttpAppender]. about log4net.http-appender HOT 4 OPEN

Try use full assembly declaration

<appender name="HttpAppender" type="Log4Net.HttpAppender, Log4Net.WebServiceAppender">

from log4net.http-appender.

Hello, I'm getting the same error with this configuration:
<appender name="HttpAppender" type="Log4Net.HttpAppender.AsyncBatchHttpAppender, Log4Net.HttpAppender"> using log4net v2.0.4. Is it possible that the library was compiled for v1.2.10.0?
When I change the log4net version to v1.2.10.0, I stop getting this error and the library starts working properly.
Is there something I can do to help?

Facing exactly same issue.

I don't quite understand what your problem is (I am not the author of this library, just shared some tip - for clarity).

So you resolved your issue or not? Type declaration is quite a simple thing. You enter the class name and namespace where it can be found. Sometimes it's necessary to type assembly name as well. But assembly is search in specified path order (https://docs.microsoft.com/en-us/dotnet/framework/deployment/how-the-runtime-locates-assemblies, https://docs.microsoft.com/pl-pl/dotnet/core/dependency-loading/default-probing). Maybe you have several versions of this library in your packages folder? Maybe different versions are referenced across solution? Hard to say without my crystal ball.
