Hello ,

We have been Using VS2015 as the IDE for development. We Upgraded to  Driver 2.12.2 and now the Project does not load in VS2015. We get the following error:

'

MongoDB.Libmongocrypt.targets error : Invalid static method invocation syntax: "[MSBuild]::IsOsPlatform('Windows')". Method '[MSBuild]::IsOsPlatform' not found. Static method invocation should be of the form: $([FullTypeName]::Method()), e.g. $([System.IO.Path]::Combine(`a`, `b`)).
