Actually, the cause for this error is very small and simple. But because the error doesn’t clearly state what’s wrong and there’s not a lot to be found about this, I’ll post it here anyway… Otherwise, you might be looking for this for a while, while it’s so easy!
When you are loading an assembly using reflection and you want to call a method from the class that’s in the loaded assembly, you might get the error
Object does not match target type. Even when the method is void and takes no parameters this error can occur. In that case: make sure the methods in the assembly you loaded are static.
Yes, I did have this error myself and yes, I found out the static-part myself eventually. But it took me half an hour. Let’s just say it was at the end of a very, very long day….. 😉
