Cannot compile source code after download

[LeoJHarris]

Having a problem trying to compile the latest version of this library. Getting an issue as per the below after I did a download of the source code and attempt to build project. I am going to guess there is an easy fix but not sure what that is. I am planning to look into the source code to try fix this ticket I created https://github.com/xamarin/XamarinCommunityToolkit/issues/1139 I've added the project source as a direct reference to my project.

Source file specified multiple times

Looks like some files are imported twice. Could you check git for changed files? Maybe project file got updated in a way that imported the same files multiple times.

@maxkoshevoi that might be the case, I was using a visual studio extension that's meant to import multiple projects in one go https://marketplace.visualstudio.com/items?itemName=MaciejGudanowicz.AddMultipleProjectsToSolution plus I was ton the preview channel of VS so something might have gone wrong but I'm guessing this extension didn't work properly as I removed and re-added the project without the use of this extension and it worked. Closing the issue.
