I used to create the assemblies in .netCore using the below code,
var myAssembly = AssemblyLoadContext.Default.LoadFromAssemblyPath(@"Directory_Path");
var myType = myAssembly.GetType("Class_Name");
var myInstance = Activator.CreateInstance(myType);
In .Net Standard also, it should work.
Edit: Try this for .NetStandard,
var assembly = Assembly.LoadFrom("directoryPath");
var type = assembly.GetType("ClassName");
var instance = Activator.CreateInstance(type);

I am getting this error when i run the application "Could not load file or assembly 'System.Runtime.Loader, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified."

Is the System.Runtime.Loader assembly referred in your application? If yes, please check if multiple versions are installed in different projects and correct them
Badri
Run this, "%userprofile%\.nuget\packages\System.Runtime.Loader" This should let you know the locally installed versions
Badri
It will show whatever installed in your system. If you want to check in your solution, you need to use the solution explorer in VS and search it

Thanx a ton badri. But i just did a workaround by passing the Assembly object itself to the .Net standard library project. There is one more question i have posted which is for How to use C# code to list all Namespaces in the .Net Standard library from within the .Net standard project itself. Can you see that. It is here stackoverflow.com/questions/59026604/…
