Updating development environment is required

[sygh-JP]

It seems that FBX SDK 2020.3.2 is the last version that supports VS2015.
The latest FBX SDK 2020.3.4 has been dropped the support for VS2015.

My development environment should be upgraded such as to VS2022.

Additionally, I have a plan to migrate from .NET Framework to any .NET, but the version is a problem to be examined.
The support lifecycle of .NET is a bit complicated and too short even in LTS versions.
OTOH, .NET Framework will be probably supported until at least the end of Windows 11 because .NET Framework 4.8 is a built-in component.
