Microsoft Visual Studio 2019 Build Tools 16.9.0-16.9.5 (x86/x64)

More specifically, unlike the full studio, this installer does not include the VS IDE Core component and, accordingly, you cannot install the visual development environment through BuildTools. Through this, an attempt is made to reduce the weight of the installer and reduce the size and impact on Windows. BuildTools does not provide any additional features (that is, this is a type of "toolchain from small soft" ... it seems to me it would be worthwhile to call this modification so that everything would be clear at once ... but apparently the desire to be unique and inimitable prevents them from using calmly already available terms ).
Installation:
• Disconnect from the Internet ... so that the installer does not download the lists of installed components for the most recent version ... the one that may not yet be in the distribution. If this happens, then the installer may no longer have enough of what is in the distribution and errors with downloading may appear
• If the installer does not have access to the Internet, then install certificates for self-diagnosis of the installer by executing Certificates_Setup.cmd
ON BEHALF OF THE ADMINISTRATOR • Then run Setup_BuildTools . cmd, where X specifies the version number you want to install (i.e. 16.9.X)

This distribution presents an almost complete BuildTools edition of VS2019 studio. Who needs only a C ++ compiler, see here . If you need to install / update NOT BuildTools studio edition, then look here
In this distribution, the BuildTools edition is presented, from which ONLY old versions of C ++ (corresponding to studio versions 16.0-16.8) have been removed and nothing else. This had to be done so that the distribution size was smaller and it would already be advisable to have a separate BuildTools distribution from the AIO. Whoever needs old compilers, you can install BuildTools from this distribution (well, either give the installer access to the Internet ... he will then download the necessary one during installation)
The removed components are so unimportant that you simply cannot select them from the first tab of the installer. On the second tab, in order not to run into missing components, you should not select those components that contain "14.2x" in their name, where x is from 0 to 7 ... the latest version (14.28) is naturally left. In short, speaking graphically from C ++ compilers, only this is left:

Apart from the old C ++ components, nothing has been cut out. Those. if you are not interested in C ++ then you can safely put anything you want offline

There may be difficulties with updating BuildTools:
The essence of the problem with updating BuildTools in offline mode is that the installer sometimes does not see some of the downloaded components if the name of the folder from which the installer is launched is NOT the same as when installing BuildTools. If this happens to you, then you need to either restart the installer but from the same folder, or simply rearrange BuildTools, or provide Internet access.
