I don’t think that’s documented and you are welcome to file an issue on microsoft/docs for that.

I don’t expect many people should be setting this though, if at all. Note that this is not the same as a global.json resolution. The .NET Core SDK hive that was resolved depends on the global.json. If you don’t set this env var, the sdk props/targets are resolved next to the .NET Core SDK.

However, if you set that env var, then props/targets are going to be found based on that location. At this point in time, I don’t believe this would be a change we would make, given all the other things we are working on.

I will take this as a data point though, if we see this more often, we will consider additional logging.

@aateeque do you, by any chance, have MSBuildSDKsPath environment variable set and pointing to your 2.1.104 SDK? That would explain why we were using props/targets from that location instead of from the latest SDK.
