Task could not find "AL.exe" using the SdkToolsPath
Easiest thing to do is copy al.exe
from
C:\Program Files\Microsoft SDKs\Windows\v7.1\bin\NETFX 4.0 Tools\
(For Windows 10 from
C:\Program Files (x86)\Microsoft SDKs\Windows\v10.0A\bin\NETFX 4.6 Tools)
to
C:\Program Files\Microsoft SDKs\Windows\v7.0A\bin\NETFX 4.0 Tools\
As I got this issue in VS2019 after a fresh install of both Windows and Visual Studio 2019 I thought it might be good to share:
Installing Microsoft.Net.Component.4.7.2.SDK from the Visual Studio installer fixed it for me!
Do you have any resource files in your project? Try to delete all of them and build your project again.I've got exact the same error and after deleting the resource files (*.hrsx) my build worked again.
Maybe it helps.
