New version of package with serilog 2.x dependency

[mwijnands]

Would it be possible for you to reference serilog 2.x and create a new package?

I am using Serilog 2.4 and just because I use AutofacSerilogIntegration, I have to add Assembly Redirects to Serilog 2.0.0.0 in every project now...

Thanks for the code!

Thanks for the reminder! There's already a -dev package out there with 2.x support, but it's time to move it into RTM. Merging #16 shortly.
