I just upgraded a project from Visual C++ 2012 to Visual C++ 2017 and I'm getting build failures from MSBuild:
C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\Common7\IDE\VC\VCTargets\Microsoft.Cpp.Current.targets(64,5): error MSB4062: The "SetEnv" task could not be loaded from the assembly C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\Common7\IDE\VC\VCTargets\Microsoft.Build.CppTasks.Common.dll. Could not load file or assembly 'Microsoft.Build.Utilities.Core, Version=126.96.36.199, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified. Confirm that the declaration is correct, that the assembly and all its dependencies are available, and that the task contains a public class that implements Microsoft.Build.Framework.ITask. [C:\src\my-project.vcxproj]
The Fusion log shows bad things:

Microsoft.Build.CPPTasks.Common cannot find Microsoft.Build.Tasks.Core
It seems you are using the old MSBuild.exe from .NET framework. You should use the MSBuild.exe from following location after you upgraded your project from VS2012 to VS2017:
C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\MSBuild\15.0\Bin\MSBuild.exe
That because MSBuild is now part of Visual Studio!:
Starting with Visual Studio 2013, the 2013 version of MSBuild will ship as a part of Visual Studio instead of the .NET Framework. This transition allows us to more rapidly evolve MSBuild.
Hope this helps.
You will have to edit the file in this directory:
C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\Common7\IDE\VC\VCTargets
Edit line 17 into:
<UsingTask TaskName="ClangCompile" AssemblyFile="C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\Common7\IDE\VC\VCTargets\Microsoft.Build.CppTasks.Common.dll"/>
Be warned if this does create additional problems you might need to install proper MSBuild.
