MSBuild Errors while building VSTO Addin's

Question

I recently migrated my VSTO Add in projects from "VS2008 and office 2007" to "VS2013 and office 2013", Changes took place as below settings.

1. .Net Framework version from 3.5 to 4.5(While upgrading project).

2. I have added VSTO 2013 PIA assemblies to reference.

That's it, when i tried to compile i have faced below MSBuild errors.

C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v12.0\OfficeTools\Microsoft.VisualStudio.Tools.Office.targets(268,13): error MSB4064: The "TargetFrameworkVersion" parameter is not supported by the "SignFile" task. Verify the parameter exists on the task, and it is a settable public instance property.
C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v12.0\OfficeTools\Microsoft.VisualStudio.Tools.Office.targets(264,9): error MSB4063: The "SignFile" task could not be initialized with its input parameters.

and i have tried to find solutions over the internet but couldn't find much, Any Solutions for this problem will be helpful.

Answer 1

This is still not working as of Visual Studio 2015 Update 3.

I had to actually modify the C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v14.0\OfficeTools\Microsoft.VisualStudio.Tools.Office.targets file and remove the TargetFrameworkVersion attribute from the SignFile task.

Answer 2

The problem was not the MSBuild, **

i have updated visual studio update 3 to update 4

and started working like charm.

I think Microsoft guys have moved something around from Update 3 to update 4 but this has been reported several times in many forums and i don't know why they have not mentioned it but this is one effective solution.

Answer 3

I ran into this issue. The problem is that Update 3 of Visual Studio 2013 moved some things around, so you need to use the MSBuild that is now installed with Visual Studio 2013 (or the standalone build tools for build servers). You need to make sure that you're using the correct MSBuild (currently at C:\Program Files (x86)\MSBuild\12.0\Bin), and it should work.
