How release file loaded with Assembly.LoadFrom() ?

load the file into a byte array and use Assembly.Load(byte[]) instead.

        private void GenerateWebserviceAgents()
        {
            byte[] rawAssembly = LoadFile(webServiceAssemblyPath);
            Assembly ass = Assembly.Load(rawAssembly);
            if (ass == null) return;

            foreach (Type t in ass.GetTypes())
            {
                
            }
        }

        // Loads the content of a file to a byte array. 
        static byte[] LoadFile(string filename)
        {
            FileStream fs = new FileStream(filename, FileMode.Open);
            byte[] buffer = new byte[(int)fs.Length];
            fs.Read(buffer, 0, buffer.Length);
            fs.Close();

            return buffer;
        }
