Hi MrValentine and thanks for the welcome~
I shall try to be clearer.
The error I receive, which you can see in the first post, is when I attempt to compile image assets using the Pipeline tool. So, when i click the Build button in the pipeline tool after adding assets.
I am using a Windows 10 machine, I have Visual Studio 2015 Community installed, DirectX, and the appropriate runtime libraries. I have attempted to use the pipeline tool from the Development build of Monogame unsuccessfully, and then the 3.5.1 stable release, also unsuccessfully.
The rest is not important in this issue. To attempt to simplify the problem further, I created a new ‘Cross-Platform’ project (as the Windows Desktop template seems to create a broken project)…
I am able to Build this project.
However, when attempting to use the Pipeline tool to compile image assets, I receive described above.
I hope that this has made the issue clearer.
