You can use a combination of:

• Type.GetType(string)
• Type.GetMethod(string)
• IIocResolver.ResolveAsDisposable(Type) — by ABP
• MethodInfo.Invoke(Object, Object[])

// var appServiceName = "MyAppService";
// var methodName = "MyMethod";
// var input = new object[] { new MyInput() };

var appServiceType = Type.GetType(appServiceName);
var method = appServiceType.GetMethod(methodName);

using (var appService = IocResolver.ResolveAsDisposable(appServiceType))
{
    var output = await (Task)method.Invoke(appService.Object, input);
}
