Failed to create importer 'TiledMapImporter'

Hi all,

I have just updated my very simple project from the nuget MonoGame.Extended packages to the prerelease versions (3.6.0-beta0001).

I updated the Content Pipeline package as well, and updated the reference in the Pipeline tool.

Since doing this, I am getting this error when building:

n1>  Failed to load assembly 'C:/Work/SimpleGame/packages/MonoGame.Extended.Content.Pipeline.3.6.0-beta0001/lib/netstandard2.0/MonoGame.Extended.Content.Pipeline.dll': Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information.

Any suggestions?

Fixed using the advice from dararish on
