Error The “ResolveWixReferences” task could not be loaded from the assembly

Question

WiX Toolset v3.11.1

WiX Toolset Visual Studio 2015 Extension

Try Integrating WiX Projects Into Daily Builds as following article. http://wixtoolset.org/documentation/manual/v3/msbuild/daily_builds.html

WixSetup64bit.wixproj at C:\Work\TC\WixSetup64bit\

wix311-binaries.zip is extracted to C:\Work\TC\wix\v3.11\

How to fix following error?

Severity Code Description Project File Line Suppression State Error The "ResolveWixReferences" task could not be loaded from the assembly C:\Work\TC\wix\v3.11..\wix\v3.11\wixtasks.dll. Could not load file or assembly 'file:///C:\Work\TC\wix\wix\v3.11\wixtasks.dll' 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. WixSetup64bit C:\Work\TC\wix\v3.11\wix2010.targets 735

rebuild again, the error changes to Severity Code Description Project File Line Suppression State Error The "ResolveWixReferences" task was not found. Check the following: 1.) The name of the task in the project file is the same as the name of the task class. 2.) The task class is "public" and implements the Microsoft.Build.Framework.ITask interface. 3.) The task is correctly declared with in the project file, or in the *.tasks files located in the "C:\Program Files (x86)\MSBuild\14.0\bin" directory. WixSetup64bit C:\Work\TC\wix\v3.11\wix2010.targets 735

Previous Answer: Not sure, and it is not a 100% match, but maybe check this answer: WiX Toolset: Creating a simple WiX project breaks in VS2017: The "CreateProjectReferenceDefineConstants" task was not found

In Essence: Is the .NET framework 3.5 installed on your build computer?

If not, please try to add it: WinKey + Tap R => appwiz.cpl => Enter => Turn Windows features on or off. Tick the ".NET Framework 3.5" entry and install.

Important: now run Windows Update to check for security updates.

Or - obviously - get the correct deployment package installed from your distribution guys, if you are in a managed environment with standardized software.
