Mono runtime error: Could not load file or assembly Microsoft.VisualBasic, Version=8.0.0.0

[obaboli]

Hi! I'm using the mono layer to run a closed source .NET exe. It looks to be using .NETFramework Version 4.0. I'm able to run one of the CLIs but the second results in a runtime error below:

ERROR: System.IO.FileNotFoundException: Could not load file or assembly 'Microsoft.VisualBasic, Version=8.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies.
File name: 'Microsoft.VisualBasic, Version=8.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'

We currently use yocto kirkstone and include only "mono" in our IMAGE_INSTALL:append. Are there any additional recipes to get this assembly in our yocto build?

Hi @obaboli. Interesting question. I may be wildly incorrect but it looks as though we may need support for this

https://github.com/mono/mono-basic

[Edit: Off the top of my head we don't currently have a recipe for this...]

Makes sense.

I did notice there is a mono-basic recipe inside recipes-mono. Tried to build it and got some errors with kirkstone.

Any progress here? If not I'll close due to inactivity
