   It's a dependency issue, not a Wisej issue.

   The reason why it works in a console app and not in a Wisej app is because of this line here 

   What this line does is that it essentially imports what is called a metapackage implicitly, named Microsoft.AspNetCore.App , and Microsoft.Extensions.Logging.Abstractions is part of it.

   To fix it, add this to web.config:

   <runtime>
   		<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
   			<dependentAssembly>
   				<assemblyIdentity name="Microsoft.Extensions.Logging.Abstractions" publicKeyToken="adb9793829ddae60" culture="neutral" />
   				<bindingRedirect oldVersion="1.0.0.0-9.9.9.9" newVersion="8.0.0.2"/>
   			</dependentAssembly>
   			<dependentAssembly>
   				<assemblyIdentity name="System.Runtime.CompilerServices.Unsafe" publicKeyToken="b03f5f7f11d50a3a" culture="neutral" />
   				<bindingRedirect oldVersion="1.0.0.0-9.9.9.9" newVersion="6.0.0.0"/>
   			</dependentAssembly>
   		</assemblyBinding>
   	</runtime>

   Hello Julie,
   Yes, its works.. I didn’t know that the Microsoft.AspNetCore.App contains the Microsoft.Extensions.Logging.Abstractions.
   Thank you.
   Have a nice day
