I got the same problem as Build Error + Creating VSTO addin for excel 2010
After making the change according to the solution, I got the new error:
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.
I have installed VS2013 on the same machine so I change version=12.0.0.0 but I got a new error:
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
'Microsoft.Build.Framework.ITask'.
I know it's an old post, but maybe I have a solution for you...
I ran into exactly the same problem and I have to tell you that the "InitializeDefaultProperties" exception is not fix-able for VS2010.
First of all:
Make sure that your Visual Studio 2010 installation is not modified, anyway make a clean install just to be sure.
If you modified the C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v10.0\OfficeTools\Microsoft.VisualStudio.Tools.Office.targets revert your changes.
If you now try to build your VSTO Project the following error should apppear:
The "FindRibbons" task could not be loaded from the assembly
Microsoft.VisualStudio.Tools.Office.BuildTasks, Version=10.0.0.0,
Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a. Could not load file
or assembly 'Microsoft.VisualStudio.Tools.Office.BuildTasks,
Version=10.0.0.0, 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.
My Solution:
--> Open Visual Studio 2010 (you dont need to load a Project)
--> Go to Help an click About Microsoft Visual Studio
--> Check Version
Microsoft Visual Studio 2010 Version
10.0.40219.1 SP1Rel
Microsoft
.NET Framework
Version 4.5.51209 SP1Rel
If it says RTMRel download the Microsoft Visual Studio 2010 SP1 from here: http://go.microsoft.com/fwlink/?LinkId=210710
It includes the necessary VSTO and VSTO 4.0 Runtime.
If thats not the Problem, I'm sorry...
As I encountered the same problem upgrading our build server... I am gonna put the solution here in case anyone needs it.
I think the way to solve this is to fix your GAC.
Open the .target file of that tool by notepad and take a look at the UsingTask tag, you should get something like
<UsingTask TaskName="InitializeDefaultProperties" AssemblyName=" Microsoft.VisualStudio.Tools.Office.BuildTasks", Version=11.0.0.0,..., PublicKeyToken=sthsthsth
Then, go to your GAC files, e.g. C:\Windows\Microsoft.NET\assembly\GAC_MSIL\Microsoft.VisualStudio.Tools.Office.BuildTasks
Then, create a new folder: v4.0_11.0.0.0_sthsthsth,
which is:
v<.NETFramework Version, mostly 4.0>_<Assembly Version>_<PublicKeyToken>
And then, put the .dll file of Microsoft.VisualStudio.Tools.Office.BuildTasks in it.
This dll should be obtained when you install VSTO either by directly install (VSTO2010) or by Visual Studio installer
e.g.
C:\Program Files (x86)\Microsoft Visual Studio\2017\BuildTools\MSBuild\Microsoft\VisualStudio\v15.0\OfficeTools\Microsoft.VisualStudio.Tools.Office.BuildTasks.dll
for Visual Studio 2017 and then directly place the dll inside the folder created
Then this issue should be fixed. Good luck
