When I am trying to create a Xamarin project I get the following error:
Could not load the file or assembly 'Xamarin.VisualStudio.Contracts',Version=16.8.4.0, Culture=neutral,

I am new to Xamarin and have created a cross-platform project in Visual Studio 2017.
When I build that project, I am getting the below issue:
Severity: Error
Code: MSB4062
Description: The "Xamarin.Forms.Build.Tasks.XamlGTask" task could not be loaded from the assembly C:\Users\E6430\.nuget\packages\xamarin.forms\3.1.0.637273\build\netstandard2.0\Xamarin.Forms.Build.Tasks.dll. Could not load file or assembly 'netstandard, Version=2.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51' 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.
Project: TestApp
File: C:\Users\E6430\.nuget\packages\xamarin.forms\3.1.0.637273\build\netstandard2.0\Xamarin.Forms.targets
Line: 84
My NuGet is also get coloured with yellow colour.
Try this:
Unload project from the solution
Restart visual studio and open solution
Reload project
Rebuild
If persist:
Just run Visual studio as Administrator!

I have an "old" XAML Build Definition, made in Visual Studio; which builds a solution and following runs unit tests.
Now I've tried to make the same in the new TFS 2015 web surface.
I've created a build task, following Visual Studio Test.
But now the Test-Task exit with code 1 and gives me a lot of
"System.IO.FileNotFoundException: Could not load file or assembly" errors.
And also "Warning: MSTestAdapter failed to discover tests in class ..."
All the DLLs are where they have to be, the new definition has the same directory structure like the old one, but the test-task says there are missing assemblys.
Any ideas?
Update:
No, I still have the same error messages:
Warning: Unable to load types from the test source 'J:\xyz-Tests.dll'. Some or all of the tests in this source may not be discovered. If you are running unit tests for Windows Store apps and referencing custom WinMD type then please visit http://go.microsoft.com/fwlink/?LinkId=238340 for more info.

This should exactly be the issue mentioned in below article, please try following the workaround to fix it:
Running Coded UI Tests built using Visual Studio 2013 with Team Foundation Server 2015
Test execution is failing in this scenario because test execution
engine is not able to resolve the old version binaries while executing
tests in a 14.0 environment (TFS 2015).
So, you need to update the projects to reference the new versions of the assemblies (VS 2015 in this scenario) using the assembly bindings in the test projects config file.
As a workaround to this issue, add an ‘app.config’ file to your
solution (See how to add app.config
https://msdn.microsoft.com/en-in/library/ms184658.aspx) and update the
contents of the file with the shared on OneDrive . The updated
configuration files contain assembly redirects from version 12.0 to
14.0, which will make sure that the test agent machine is able to resolve the framework assemblies. Check-in the updated configuration
file into the source control repository and run the BDT scenario once
again. The tests should run fine this time. If the test execution
again throws an error complaining version mismatch for some other
assembly, add the assembly to the app.config file and retry.

I am unable to use the Add... REST API Client... option in Visual Studio 2015 with all the latest updates and Azure Tools v2.9 installed. When I select the option I am presented with the proper dialog to provide either a url or the file path for the swagger json file. Regardless of which option I select I get the following error message:
Generating client code and adding to project started
Generate client code for REST API with following parameters:
REST API Name: ToDoListAPIClient, Base namespace: ToDoListAPI, Metadata file path: C:\Users\ken\AppData\Local\Temp\WebToolsAutoRest\ToDoListAPIClient\201702032141192827\swagger.json

How can I resolve this problem?
Make sure you download the proper version of the Newtonsoft.Json package by running the command:
PM> install-package Newtonsoft.Json -Version 7.0.1
Then copy the Newtonsoft.Json assembly (version 7.0.0.0) to C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE.
This should work around the issue.
I have a project that builds and is publish correctly before I moved to Windows 10. After I updated to Windows 10 I can build and test my project but I cannot publish my MVC project. It gives me the following error which I do not understand:
Could not load file or assembly 'Microsoft.Web.Deployment, Version=9.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.
I added Microsoft.Web.Deployment from nuget but I still get the same error.
Following will solve your problem
Downloaded Web Deploy 3.5, from http://www.iis.net/downloads/microsoft/web-deploy
install complete package
Then open your project in VS 2013.
Publish your project.
Thanks
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,

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
