Note that when you login, the .NET client API initializes a local security token based on your credentials.  It does not actually make a call however, until you make your first request.  At that time, the forms service will attempt to authorize you based on your token.  In the above example, the first call is for the user entry.

The LoginAs method for an existing user:

This new method allows you to login as any of the existing tenant users provided you can pass in the tenant's admin user and password. This is quite convenient when you want login using the same user that is logged into your application without having to know their password.

IDictionary<string, string> customParams = new Dictionary<string, string>();
       customParams.Add("autoLogin", "true");


FormsService service = new FormsService("http://localhost:8082", "yourappname"); 
          service.LoginAs( 
              "myuser", 
              "tenantAdminUserName@myTenantName", 
              "tenantAdminPassword",
              false,
              null, null, null, null,
              customParams);

UserEntry user = service.GetUser(“myuser”); 
     
          //   interact with frevvo   
  
service.Logout();

The LoginAs method for a new/undefined user:

When your tenant is configured with the Delegating Security Manager, you can use the loginAs() method to automatically create new/virtual users.

IDictionary<string,string> customParams = new Dictionary<string, string>(); 
     ApplicationQuery query = servicecustomParams.CreateApplicationQuery(nullAdd("autoLogin", "true");

string[] roles  ApplicationFeed apps = service.Query(query);= { "frevvo.Designer" };

FormsService service = new FormsService("http://localhost:8082", "yourappname");      foreach

How do I pre-populate values when creating an instance?

When creating a form instance, you can supply data to pre-populate fields.  There are a couple of ways to do this.  The first way is to supply a name value collection, which holds control names and values.  The second way is to supply an XML document, with control names and values. Suppose your form has two text fields, named A and B respectively.  Also, suppose you wish to prefill these 2 controls with values, as shown:
