The host directory is a C#-application with .Net Framework 4.7.2.

But I get the following error:

Server Error in '/YAF' Application.

Configuration Error

I saw that there are people here that have obviously integrated the system.codecom-section in their web.config.

With me it won't work.

I tried to put this section into the Web.Config in the YAF-directory. Did not work.

I added the ROSLYN-subdirectory to the bin-directory. Did not work.

Could you please help me? Thanks.

But if I understand correctly you want to run yaf as separate application. What you need that section for in yaf?
