Add support for net standard 2.0 about microsoft.extensions.logging.log4net.aspnetcore HOT 15 CLOSED

I just checked nuget and .net standard 2.0 is not listed as a supported framework.
Do yo know when this release will be available?
Thanks

This package downgrade is because the "nearest" version to the project wins.
In this case your project (which also references log4net) references a lower version of the sockets than log4net does. Since the log4net reference is to the sockets is not "direct" it looses. The build detects this and warn about this.
I do not know exactly where the reference to the lower version of the socket package comes from (maybe from the default netcoreapp3.0 dependencies).
You can easily solve this by adding the higher version of the socket reference directly (in the same project as your log4net reference is added). Be aware that this might not solve all your version conflicts, so adding a meta package might be the better choice.

Try adding the latest (3.0.0) version of Microsoft.NETCore.Targets package.

Not sure if this is the only and best solution. But it feels much better than supressing the warning, which is supposed in many forums.

Hello @tcz717 ,

Thank you very much by your kindly words.

Can you explain me something about the scenario that you are trying to solve with this nuget package?

For me, your question is similar to #3, and I think that the answer could be the same, but I want that, if you can, expose me the scenario in order to evaluate if the .net standard support is reasonable or not.

Thank you very much.

Hi @huorswords

I am writing a RPC lib in .net standard 2.0 and its network part is based on DotNetty. DotNetty has an internal logging system that supports Microsoft.Extensions.Logging.ILoggerFactory interface, but my whole system uses log4net to log. So I need an adapter to connect these two parts.

Thanks for your reply.

Hello @tcz717,

After reviewing your request, and after checking some of the other Logging providers that also supports Microsoft.Extensions.Logging library, I have just included .NET Standard 2.0 as supported target framework of this project.

The nuget package will be available soon on nuget.org.

Thank you very much by your suggestion.

Regards.

Hello @dgxhubbard,

Sorry but, on last version of the nuget package, .Net Standard 2.0 is one of the dependencies...

Where have you checked it? From VS? From nuget.org portal?

Thank you. Regards.

I opened the manage nuget packages for solution click on browse and type in "log4net"
The last one listed is .net standard 1.3

from microsoft.extensions.logging.log4net.aspnetcore.

I see the problem. I searched here found log4net and thought this was log4net. I looked at the logging extension and there is a .net standard 2.0. Alas, I was looking for log4net thought.
Sorry about that.

from microsoft.extensions.logging.log4net.aspnetcore.

Oh! I see...

Cool, I have worried about it. :)

Anyway, thank you by your question.

Hi, I just tried to add the log4net nuget for a netstandard2.0 library and had the same problem like dgxhubbard. What is excatly the name i have to search for in the nuget package manager of visual studio?

Hello @JensFu ,

The official log4net nuget package (https://www.nuget.org/packages/log4net/) it is compatible with .NET Standard 1.3, so it should be compatible with any library created on .NET Standard 2.0.

At the other hand, the Microsoft.Extensions.Logging.Log4Net.AspNetCore package it is compatible with .NET Standard 2.0, and imports automatically the reference from log4net v.2.0.8 package.

Please, let me know any thought on this.

Thank you.

from microsoft.extensions.logging.log4net.aspnetcore.

Once you add the log4net reference to .NETStandard 2.0 project you get a lot of nu1605 warnings

https://docs.microsoft.com/en-us/nuget/reference/errors-and-warnings/nu1605?f1url=https%3A%2F%2Fmsdn.microsoft.com%2Fquery%2Fdev15.query%3FappId%3DDev15IDEF1%26l%3DEN-US%26k%3Dk(NU1605)%26rd%3Dtrue

I think there a need to make log4net .NETStandard 2.0 compatible

from microsoft.extensions.logging.log4net.aspnetcore.

Completely agree @petertsu , but unfortunately log4net is a "third-party" library on this project.

Maybe you can propose it as an enhancement on the log4net repo: https://github.com/apache/logging-log4net.

Hi, I have been trying to deploy web API on Lambda AWS but every time I get this error in publishing on AWS.
error NU1605: Detected package downgrade: System.Net.Primitives from 4.3.0 to 4.0.11. Reference the package directly from the project to select a different version.

Thanks a lot. Adding Microsoft.NETCore.Targets v3.0.0 nuget package in my project resolved the issue.
