I am attempting to connect some C# code to an alfresco database, and I have two questions.  Firstly, I am unsure of where to find the 'Repository ID', I have looked at the details page of the repository I need to connect to, but I didn't see anything that seemed to fit the bill.
Additionally, when I run the code below, I get a result of "A first chance exception of type 'DotCMIS.Exceptions.CmisConnectionException' occurred in DotCMIS.dll" but have been unable to find any information about what this message entails.

<blockcode>
try
        {
            Dictionary<string, string> parameters = new Dictionary<string, string>();
            parameters[DotCMIS.SessionParameter.BindingType] = BindingType.AtomPub;
            parameters[DotCMIS.SessionParameter.AtomPubUrl] = "http://localhost:8080/alfresco/service/cmis/index.html";
            parameters[DotCMIS.SessionParameter.User] = "admin";
            parameters[DotCMIS.SessionParameter.Password] = "password";
            parameters[DotCMIS.SessionParameter.RepositoryId] = "<repositoryId>";

            SessionFactory factory = SessionFactory.NewInstance();
            ISession session = factory.CreateSession(parameters);

            IFolder rootFolder = session.GetRootFolder();
            foreach (ICmisObject cmisObject in rootFolder.GetChildren())
            {
                Console.WriteLine(cmisObject.Name);
            }
        }
        catch(Exception ex)
        {
           Console.WriteLine(ex.ToString());
        }
</blockcode>

I thought the error might be due to me leaving a placeholder value for 'RepositoryID', but I'm not sure.
Any help or information you could offer would be very much appreciated.
Thank you in advance.

You are using wrong atom url :
for CMIS 1.0, the URL is:

http://localhost:8080/alfresco/api/-default-/public/cmis/versions/1.0/atom
‍‍‍

for CMIS 1.1, the URL is:

http://localhost:8080/alfresco/api/-default-/public/cmis/versions/1.1/atom
‍‍‍

and you don't need repositoryId parameter, you can write it like follwing

          try
            {
                Dictionary<string, string> parameters = new Dictionary<string, string>();
                parameters[DotCMIS.SessionParameter.BindingType] = BindingType.AtomPub;
                //parameters[DotCMIS.SessionParameter.AtomPubUrl] = "http://localhost:8080/alfresco/api/-default-/public/cmis/versions/1.1/atom";
                parameters[DotCMIS.SessionParameter.AtomPubUrl] = "http://localhost:8080/alfresco/api/-default-/public/cmis/versions/1.0/atom";
                parameters[DotCMIS.SessionParameter.User] = "admin";
                parameters[DotCMIS.SessionParameter.Password] = "admin";
                //parameters[DotCMIS.SessionParameter.RepositoryId] = "<repositoryId>";

                SessionFactory factory = SessionFactory.NewInstance();
                IList<IRepository> repos = factory.GetRepositories(parameters);
                ISession session = repos.ElementAt(0).CreateSession();
 
                IFolder rootFolder = session.GetRootFolder();
                foreach (ICmisObject cmisObject in rootFolder.GetChildren())
                {
                    Console.WriteLine(cmisObject.Name);
                }
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.ToString());
            }
