Question

I am loading assemblies using Assembly.LoadFile(assemblyFilePath) in a loop and I want to avoid calling Assembly.LoadFile if the assembly has already be loaded once. Should I be concerned about calling Assembly.LoadFile repeatedly for a DLL that has already been loaded? Thanks.

No you don’t need to be concerned because if an assembly has already been loaded it won’t be loaded again

If you call Assembly.LoadFile() then you can load the same assembly multiple times but only if you are loading assembly from different path each time. You can use Assembly.Load() which will load an assembly only once. You can also find about already loaded assemblies in current app domain using

Assembly[] asms = AppDomain.CurrentDomain.GetAssemblies();
