Why SLAB SqlDatabaseSink stopped writing to Traces table?

SLAB SqlDatabaseSink stopped writing to Traces table

I added a FlatFileSink in parallel to make sure the listener is not the issue, which writes fine to a file. I also have a Unit Test for the SqlDatabaseSink which works fine, but when subscribing from the main project via Global.asax only the FlatFileSink works. Screenshots below.

Added SLAB internal event listener per @manikrish 's suggestion (thank you very much for that), here is the underlying SQLDatabaseSink error from that log "Could not load file or assembly 'Newtonsoft.Json, Version=4.5.0.0, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed'" - details below, SLAB Internal Log.

Next, I compared the reference properties of Newtonsoft.Json between main project and Unit Test project (who's SQLDatabaseSink works), both using version 6.0.8 (I believe WebApi 5.2.3 came with it), but noticed the Specific Version was False in the latter. So, I made the same change in the main project, still no luck.

Also, the main project's web.config and unit test project's app.config have the same assembly binding for it also:

  <dependentAssembly>
    <assemblyIdentity name="Newtonsoft.Json" publicKeyToken="30ad4fe6b2a6aeed" culture="neutral" />
    <bindingRedirect oldVersion="0.0.0.0-6.0.0.0" newVersion="6.0.0.0" />
  </dependentAssembly>

Next, I tried addressing the binding redirect issue by changing reference properties in web.config, packages.config, csproj; reinstalling/updating the Newtonsoft.Json and also the calling assembly's (Microsoft.Practices.EnterpriseLibrary.SemanticLogging) NuGet package based on other stackoverflow questions (links below), still no luck - same binding error in the SLAB Internal Log, there is no evidence of my biding redirect.

Infamous assembly binding error

Could not load file or assembly 'Newtonsoft.Json' or one of its dependencies. Manifest definition does not match the assembly reference

Newtonsoft.Json.dll issue when using multiple projects

Assembly mismatch despite having assembly redirect and loading correct version

Screenshots:

The root cause was a missing dependentAssembly tag around one of the assemblies in web.config:

<dependentAssembly>
    <assemblyIdentity name="System.Net.Http.Formatting" publicKeyToken="31bf3856ad364e35" culture="neutral" />
    <bindingRedirect oldVersion="0.0.0.0-5.2.3.0" newVersion="5.2.3.0" />
    <assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35" />
    <bindingRedirect oldVersion="1.0.0.0-5.2.3.0" newVersion="5.2.3.0" />
</dependentAssembly>

Thank you very much to Mani and the other SLAB team members that helped me, especially since the root cause had nothing to do with their project.
