This is the error.

The "Xamarin.Forms.Build.Tasks.FixedCreateCSharpManifestResourceName" task could not be loaded from the assembly \packages\Xamarin.Forms.2.1.0.6526\build\portable-win+net45+wp80+win81+wpa81+MonoAndroid10+MonoTouch10+Xamarin.iOS10\Xamarin.Forms.Build.Tasks.dll. 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.Project

I've tried restarting VS, rebuilding the solution, rebuilding each project in the solution, and I tried the solution from the following:

BuildTasks.Csc task could not be loaded from the assembly?

However doing that just leads me to the following error:

Unable to copy file "obj\Debug\Project.dll" to "bin\Debug\Project.dll". The process cannot access the file 'bin\Debug\Project.dll' because it is being used by another process.

I looked into this one and it seems to be "solved" by restarting VS a lot. I was also getting this error before deleting the packages folder, but after restarting I was getting the "task could not be loaded" error.

check permissions on the folder. I ran into this same issue and that's what wound up solving the problem for me. I had moved my projects to an App Drive and you need to put your security on Explicitly even if you are an admin on the PC.Bearcat9425
If your using source control, make sure you have the solution checked outInitLipton
@Bearcat9425 It looks like I have Full control on the folders.Scko
@InitLipton Yes I have the solution checked out.Scko
@Bearcat9425 okay so I think I solved it. On one of the cleans I noticed that it said it couldn't delete \Project\bin\Debug\Project.dll because access denied. So I deleted the file and cleaned and built the project again. It works now. The \bin\Debug folder now has a bunch of files in it where before it only had the one file.Scko
