Unable to fix error "Could not load System.Net.Http, Version=4.2.0.0"

On my production server I get the error:

Could not load file or assembly 'System.Net.Http, Version=4.2.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.

On my local machine it works fine, but on the server it throws the above error, so there must be a missing file somewhere. See update 3 where I tried adding the missing dll, which then throws a different error.

I followed instructions in these links:

• Strange issue with System.Net.Http 4.2.0.0 not found
• https://github.com/Azure/diagnostics-eventflow/issues/155
• https://github.com/dotnet/standard/issues/891

As also stated in the last link, I' in the same scenario where I don't yet want to migrate (https://docs.microsoft.com/en-us/nuget/consume-packages/migrate-packages-config-to-package-reference), as I don't want to run into incompatibilities, I first want to fix the current issue.

I already looked for all references of System.Net.Http (and a few others) and manually changed version numbers, this is the old codeblock in my .vbproj file:

I also commented out the entire <runtime> section in my web.config (containing the assemblyBindings).

Still, the error persists, what else can I do?

UPDATE 1

Based on @welotty's answer I did the following:

I run fuslogvw from the VS2019 Developer Command Prompt, but I just see and empty window (no applications):

I can't see where I can select a directory to analyze or any other settings for my specific app.

UPDATE 2

Based on @welotty's comment I got fuslogvw to run. I cleared all messages, build my app in Visual Studio 2019 and now see this (no mention of System.Net.Http):

I opened up System.IO log, and I get this below in the log, but als no mention of System.Net.Http)

*** Assembly Binder Log Entry  (24-Aug-2019 @ 4:47:53 PM) ***

The operation failed.
Bind result: hr = 0x80070002. The system cannot find the file specified.

First of all: how would I resolve these issues? The log states The system cannot find the file specified and secondly: I think this is not related to my actual issue?

UPDATE 3

I noticed that System.Net.Http.dll was actually missing from the bin folder on my production server. So I copied the dll from my local machine. However, then I get the error:

Cannot load a reference assembly for execution.

I checked here, but that seems awful complex for something as simple as adding a new dll to a bin folder. And not sure if it matters, but my prod server does not have the folder: C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework.NETFramework\v4.7.2.

Why am I getting this error?

I know this is old but I ran into this today with a .net 4.8 project. I was able to track down the issue and for me I'm using Swagger via Swashbuckle. It uses WebActivatorEx which requires System.Net.Http v4.0.0.0, the binding redirects it the lastest version 4.2.0.0 and so this is my fix. In my web.config. Note the newVersion is not the latest but what is utilized and required by WebActivator Ex.
