Binding exception with dynamic keyword in c#

Binding exception with dynamic keyword in c#

I am loading my assemblies at run time and I am also using Instance
Activator to get the code at the runtime. Following code will summerize
what I am doing:
dynamic powerTool;
System.Reflection.Assembly assembly = System.Reflection.Assembly.LoadFrom(
@"C:\Users\c_desaik\Desktop\PowerTool.exe");
Type type = assembly.GetType("PowerTool.Automation");
powerTool = Activator.CreateInstance(type);
Now, as you have noticed, Powertool has been declared as dynamic because I
do not want my code to fail at Compile time and I want it to resolve all
the operations at the Runtime.
While I do that the code fails to execute down the line with the following
error:
An unexpected exception occurred while binding a dynamic operation
Now I thought that the entire concept behind the dynamic keyword was to be
abl eto resove all the members and operation at the run time. How can I
resolve this error?
