moq is not compatible with System.Threading.Tasks.Extensions 4.5.3 or 4.5.4

[alejandromoncayo]

Nuget gallery dependency states it should be compatible:
https://www.nuget.org/packages/Moq/4.15.1
"System.Threading.Tasks.Extensions (>= 4.5.1)"

But on a project with System.Threading.Tasks.Extensions 4.5.3 or 4.5.4 it fails with the following error:
Message:
Initialization method Trizetto.Cap.Application.Tests.Cache.CacheServiceTests.Setup threw exception. System.TypeInitializationException: The type initializer for 'Moq.DefaultValueProvider' threw an exception. ---> System.IO.FileNotFoundException: Could not load file or assembly 'System.Threading.Tasks.Extensions, Version=4.2.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51' or one of its dependencies. The system cannot find the file specified..

using the powershell, I can see that from 4.5.0 to 4.5.2 the "version" was 4.2.0.0, but on 4.5.3 it was changed to 4.2.0.1 as displayed by the following powershell script:
Write-Output "4.5.0"
([system.reflection.assembly]::loadfile("C:\Users\admin.nuget\packages\system.threading.tasks.extensions\4.5.0\lib\netstandard1.0\System.Threading.Tasks.Extensions.dll")).FullName
Write-Output "4.5.1"
([system.reflection.assembly]::loadfile("C:\Users\admin.nuget\packages\system.threading.tasks.extensions\4.5.1\lib\netstandard1.0\System.Threading.Tasks.Extensions.dll")).FullName
Write-Output "4.5.2"
([system.reflection.assembly]::loadfile("C:\Users\admin.nuget\packages\system.threading.tasks.extensions\4.5.2\lib\netstandard1.0\System.Threading.Tasks.Extensions.dll")).FullName
write-output "4.5.3"
([system.reflection.assembly]::loadfile("C:\Users\admin.nuget\packages\system.threading.tasks.extensions\4.5.3\lib\netstandard1.0\System.Threading.Tasks.Extensions.dll")).FullName
write-output "4.5.4"
([system.reflection.assembly]::loadfile("C:\Users\admin.nuget\packages\system.threading.tasks.extensions\4.5.4\lib\net461\System.Threading.Tasks.Extensions.dll")).FullName

with the output:
4.5.0
System.Threading.Tasks.Extensions, Version=4.2.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51

Seems like they'll never learn to leave the bloody assembly version alone. 😠

@alejandromoncayo have you by any chance looked at older versions of that assembly? I'm curious whether the version has been steadily increasing or whether there were instances where they went back / reset to a all-zeroes assembly version after increasing the build number like here.

Because if increasing the build number was by mistake, and they released another version where they go back to 4.2.0.0, we'd better just wait than change our dependency.

Seems they decided to make this change permanent , as I see all versions from 4.5.0 to 4.5.2 had the same 4.2.0.0, but both 4.5.3 and 4.5.4 have 4.2.0.1.
The 4.5.3 change was on July 8, 2019.. so it seems they are sticking to the new format.
