Ich habe das gleiche Problem wieBuild Error + VSTO-Add-In für Excel 2010 erstellen

Nachdem ich die Änderung entsprechend der Lösung vorgenommen habe, habe ich den neuen Fehler erhalten:

 The "InitializeDefaultProperties" task could not be loaded from the   
 assembly 
 Microsoft.VisualStudio.Tools.Office.BuildTasks, Version=11.0.0.0, 
 Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a. Could not load file or 
 assembly 'Microsoft.VisualStudio.Tools.Office.BuildTasks, 
 Version=11.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one 
 of its dependencies. The system cannot find the file specified. Confirm    
 that the <UsingTask> 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.    

Ich habe VS2013 auf demselben Computer installiert, daher ändere ich Version = 12.0.0.0, habe aber einen neuen Fehler erhalten:

 Error  2   The "SetInclusionListEntry" task could not be instantiated from 
 the assembly "Microsoft.VisualStudio.Tools.Office.BuildTasks, 
 Version=12.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a". 
 Please verify the task assembly has been built using the same version of  
 the Microsoft.Build.Framework assembly as the one installed on your 
 computer and that your host application is not missing a binding redirect 
 for Microsoft.Build.Framework. Unable to cast object of type  Micro
 soft.VisualStudio.Tools.Office.BuildTasks.SetInclusionListEntry' to type
