Property Value

String

The name of the application for which to store and retrieve profile information. The default is the ApplicationVirtualPath value.

ProviderException

An attempt was made to set the ApplicationName property to a string that is longer than 256 characters.

Examples

The following code example shows the profile element in the system.web section of the Web.config file for an ASP.NET application. It specifies the application's SqlProfileProvider instance and sets the ApplicationName property value to MyApplication.

<profile defaultProvider="SqlProvider">  
  <providers>  
    <add name="SqlProvider"  
      type="System.Web.Profile.SqlProfileProvider"  
      connectionStringName="SqlServices"  
      applicationName="MyApplication" />  
   </providers>  
</profile>  

Remarks

The ApplicationName property is used by the SqlProfileProvider to associate profile information with different applications. This enables multiple applications to use the same database to store user information without running into conflicts between duplicate users. Multiple ASP.NET applications can use the same user database by specifying the same value in the ApplicationName property. The ApplicationName property can be set programmatically, or it can be set declaratively in the configuration file for the Web application using the applicationName attribute.

If a value is not specified for the applicationName attribute in the configuration file for the Web application, then the ApplicationVirtualPath value is used for ASP.NET applications. For non-ASP.NET applications, the default value is the ModuleName value without the file extension.

Caution

Because a single default profile provider instance is used for all of the requests served by an HttpApplication object, you can have multiple requests executing concurrently and attempting to set the ApplicationName property value. The ApplicationName property is not thread safe for multiple writes, and changing the ApplicationName property value can result in unexpected behavior for multiple users of an application. It is recommended that you avoid writing code that allows users to set the ApplicationName property unless you must. An example of an application where setting the ApplicationName property may be required is an administrative application that manages profile data for multiple applications. Such an application should be a single-user application and not a Web application.
