This was removed outright in NLog.Web.AspNetCore 5.0 due to these issues. I added a PR to fix aspnet-request-posted-body for NLog.Web.AspNetCore 5.1, it requires you to install an ASP.NET Middleware class we added the NLog.Web.AspnetCore to capture the request, that way it is thread safe. I have been using that way to capture both the request and response body at my work for that past 2 years and have had no issues under load. Just remember to use it for requests only less than 30 KB in length. Above that ASP.NET Core HttpRequest.EnableBuffering() writes to TEMP files, according to its documentation. Therefore, our default request length above which we refuse to capture the request body is therefore 30 KB, but you could override that if you want to live dangerously. (I also added about a dozen more layout renderers for asp.net and asp.net core for the upcoming release). We are also adding an example to the wiki for response body capturing middleware. If you need it re-activated before the release I can show you how to add the request middleware class and log the request body to HttpContext.Items, then use one of the existing layout renders that prints an HttpContext.Item out.
