Previously different Config objects were used for authentication.

void Example()
{
    TokenOptions iamTokenOptions = new TokenOptions(
        Apikey: "{iam-apikey}"
    );
    service = new AssistantService("{versionDate}", iamTokenOptions);
    service.SetEndpoint("{service-endpoint}");
}

Or constructors accepted TokenOptions or username and password.

void Example()
{
    service = new AssistantService("{tokenOptions}", "{versionDate}");
    service2 = new DiscoveryService("{username}", "{password}", "{versionDate}");
}

Now we use an Authenticator to authenticate the service. Available authentication schemes include IamAuthenticator, BasicAuthenticator, CloudPakForDataAuthenticator and BearerTokenAuthenticator

void Example()
{
    IamAuthenticator authenticator = new IamAuthenticator(
        apikey: "{apikey}"
    );
    var service = new AssistantService("{versionDate}", authenticator);
    service.SetServiceUrl("{serviceUrl}");
}

void Example()
{
    BasicAuthenticator authenticator = new BasicAuthenticator(
        username: "{username}",
        password: "{password}"
    );
    var service = new AssistantService("{versionDate}", authenticator);
    service.SetServiceUrl("{serviceUrl}");
}

void Example()
{
    BearerTokenAuthenticator authenticator = new BearerTokenAuthenticator(
        bearerToken: "{bearerToken}"
    );
    var service = new AssistantService("{versionDate}", authenticator);
    service.SetServiceUrl("{serviceUrl}");
}

void Example()
{
    CloudPakForDataAuthenticator authenticator = new CloudPakForDataAuthenticator(
        url: "https://{cp4d_cluster_host}{:port}",
        username: "{username}",
        password: "{password}"
    );
    var service = new AssistantService("{version-date}", authenticator);
    service.SetServiceUrl("{serviceUrl}");
    var results = service.Message("{workspace-id}", "{message-request}");
}

Constructors that did not take an Authenticator were removed.

You can supply credentials to your service using external ibm-credentials.env files.

AssistantService service = new AssistantService("{version-date}");
var listWorkspacesResult = service.ListWorkspaces();

Previously we would look for these files first in the system home directory, followed by the current project directory.

Now in order to allow developers to have different configurations for each project we look first in the current project directory, followed by the home directory.

Previously we set the service url via SetEndpoint() method.

void Example()
{
    TokenOptions iamTokenOptions = new TokenOptions(
        apikey: "{iam-apikey}"
    );
    service = new AssistantService("{versionDate}", iamTokenOptions);
    service.SetEndpoint("{service-endpoint}");
}

Now we set the service url via the SetServiceUrl() method.

void Example()
{
    IamAuthenticator authenticator = new IamAuthenticator(
        apikey: "{apikey}"
    );
    var service = new AssistantService("{versionDate}", authenticator);
    service.SetServiceUrl("{serviceUrl}");
