Answer 1

Reinstalling SDK did not help me but installing SDK+.NET 3.5 did from link below: https://www.microsoft.com/en-us/download/details.aspx?id=3138

Answer 2

After upgrading build tools in DevOps build agent to visual studio 2019, we started getting the below error for 64-bit build step of a WPF application.

C:\Program Files (x86)\Microsoft Visual Studio\2019\Professional\MSBuild\Current\Bin\amd64\Microsoft.Common.CurrentVersion.targets(3975,5): error MSB3482: An error occurred while signing: SignTool.exe was not found at path

I tried all the above answers except the ones to disable signing or signing security and nothing helped.

Disabled the default MSBUILD step

Added a cmd prompt step

The path is "C:\Program Files (x86)\Microsoft Visual Studio\2019\Professional\MSBuild\Current\Bin\MsBuild.exe"

Note: Removed amd64 from the path above.

This is still a workaround. I hope Microsoft will fix it in the following release.
