Property Value

The name of the application.

The ApplicationName is used to identify users specific to an application. That is, the same user name can exist in the database for multiple ASP.NET applications that specify a different ApplicationName. This enables multiple applications to use the same database to store user information without running into duplicate user name conflicts. Alternatively, multiple ASP.NET applications can use the same user database by specifying the same ApplicationName. The ApplicationName can be set programmatically or declaratively in the configuration for the Web application.

Caution noteCaution:

Because a single default membership 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. We recommend 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 membership data for multiple applications. Such an application should be a single-user application and not a Web application.

The following code example shows the membership Element (ASP.NET Settings Schema) element in the system.web section of the Web.config file for an ASP.NET application. It specifies that the application use a SqlMembershipProvider instance and sets the ApplicationName to MyApplication.

<membership defaultProvider="SqlProvider" userIsOnlineTimeWindow="20">
  <providers>
    <add name="SqlProvider"
      type="System.Web.Security.SqlMembershipProvider"
      connectionStringName="SqlServices"
      enablePasswordRetrieval="true"
      enablePasswordReset="false"
      requiresQuestionAndAnswer="true"
      passwordFormat="Encrypted"
      applicationName="MyApplication" />
  </providers>
</membership>
