System.IO.FileNotFoundException: Microsoft.Extensions.Logging.Filter

[jimmy84]

During debug mode in net core 2.0, the below exception was thrown on line

var logger = NLogBuilder.ConfigureNLog("nlog.config").GetCurrentClassLogger();

I believe Microsoft.Extensions.Logging.Filter was no longer available after net core 1.1, or am I missing something here?

System.IO.FileNotFoundException: Could not load file or assembly 'Microsoft.Extensions.Logging.Filter, Culture=neutral, PublicKeyToken=null'. The system cannot find the file specified.

What version are you using? Please try the latest (prerelease), thx!

[jimmy84]

I'm currently on the following version

<PackageReference Include="NLog" Version="4.5.0-rc03" />
<PackageReference Include="NLog.MailKit" Version="2.1.1" />
<PackageReference Include="NLog.Web.AspNetCore" Version="4.5.0-rc2" />

This error only occurs if Debug -> Options -> "Enable Just My Code" was unchecked in VS2017

@jimmy84 I'm guessing this is the line causing the issue, and the application runs fine after the exception has occurred.

SafeAddHiddenAssembly("Microsoft.Extensions.Logging.Filter", false);

Must admit I also hate "expected" exceptions, as I often prefer to run with catch-all-exceptions.

Guess one could improve the logic, so there is a soft-check using (iterate the array and check if the assembly is available):

AppDomain.CurrentDomain.GetAssemblies()

Would probably change the SafeAddHiddenAssemblies to receive an HashSet of assembly-names.

What is the effect of this? I can't seem to get my logging to work... only the Microsoft namespace is logged!

Edit: catch-all filters (star) work fine but only for the Microsoft namespace - using Mynamespace.* outputs nothing

I'm using the latest SPA templates (rc) - I wonder if it's related to that or not.

Ok, not related to this. It was this, for anyone looking here: #238 (comment)

@304NotModified Resolved with #245
