Can't build in visual studio 2015 because 'Microsoft.Build.Tasks.v14.0.dll' cannot be found

Question

When attempting to build in visual studio 2015, the following file is missing? This project was previously being built in VS2013.

Severity Code De

Answer 1

The assembly has been renamed. Change on the CodeTaskFactory MSBuild Task the AssemblyFile parameter to...(in your error there should be a targets file name where this task resides)

AssemblyFile="C:\Program Files (x86)\MSBuild\14.0\Bin\Microsoft.Build.Tasks.Core.dll"

Chances are someone tried to be clever and use an MSBuild property like this..(which doesn't work for MSBuild 14 but would for 12)...

AssemblyFile="$(MSBuildToolsPath)\Microsoft.Build.Tasks.v$(MSBuildToolsVersion).dll"

Just fyi...There are some others as well such as Microsoft.Build.Utilities.v12.0.dll has been renamed to Microsoft.Build.Utilities.Core.dll
