I have a program that dynamically loads dlls that have plugins. This was written originally in FW4.0, though pretty much everything is FW4.7.2 or 4.8 by now. I thought I might be able to add .NET5/6 plugins, and have run into problems. I will admit that I have not looked at this in great detail, yet, so there is a chance that I missed something simple, but I'm thinking probably not.
The code I use to load plugins is this:
The rest doesn't matter for this question, because the problem is in the very last line. When I tried making a plugin written in .NET5, it created just fine, but when I tried to load that plugin, it failed on that last line with a File Not Found exception.
The little bit of research I did showed that one of the changes from Framework to Core was that GetExportedTypes() was removed in favor of a different mechanism. Therefore, I think it might be possible to identify whether the Assembly is Core or Framework (I haven't even looked at how that would be possible, but I assume it would be), then use a different mechanism to get the types from the Assembly if it is Core.
What I need to be able to do is get types from dlls that are either framework or core. So, my question is: Has anybody done something like this, and can they show me what needs to be done?
The code I use to load plugins is this:
Code:
Dim dirLoc = "SomeFolder"
If IO.Directory.Exists(dirLoc) Then
For Each fl As String In IO.Directory.GetFiles(dirLoc, "*.dll")
Try
Dim aDLL As System.Reflection.Assembly = System.Reflection.Assembly.LoadFile(fl)
If aDLL IsNot Nothing Then
Dim tArr As Type() = aDLL.GetExportedTypesThe little bit of research I did showed that one of the changes from Framework to Core was that GetExportedTypes() was removed in favor of a different mechanism.
