excelrna.extensions.hosting's Issues

Unpacked XLL throws Assembly could not be loaded from resources

I'm getting this error when running the sample project.
I upgraded to ExcelDna 1.6.0 as well with no luck.
When running the packed version it seems to work fine.
However, while debugging, launching the unpacked version I get the error below.

ExcelDna.Integration Warning: 1 : Assembly SYSTEM.RUNTIME.COMPILERSERVICES.UNSAFE could not be loaded from resources.
ExcelDna.Integration Error: 1 : DnaLibrary AutoOpen Error : TargetInvocationException - Exception has been thrown by the target of an invocation.

Also, when running the packed version, I get this error when closing excel:

Managed Debugging Assistant 'LoaderLock' 
Attempting managed execution inside OS Loader lock. Do not attempt to run managed code inside a DllMain or image initialization function since doing so can cause the application to hang.

To be honest I'm not really sure if this is an ExcelDna issue or an issue that is caused by this package.

This is my csproj:
