Gets or sets the name of the application to store and retrieve membership information for.
Assembly: System.Web (in System.Web.dll)
The is used by the SqlMembershipProvider to group user information. By qualifying user information with an application name, you can store information for multiple applications in a single database without running into conflicts between duplicate user names. Also, multiple ASP.NET applications can use the same user database by specifying the same value in the property. The property can be set programmatically, or it can be set declaratively in the configuration file for the Web application with the applicationName attribute.
If a value is not specified for the applicationName attribute in the configuration file for the Web application, then the ApplicationPath property value for the first request made to the application is used.
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 property value. The property is not thread safe for multiple writes, and changing the property value can result in unexpected behavior for multiple users of an application. We recommend that you avoid writing code to allow users to set the property unless you must. An example of an application where setting the 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 in the system.web section of the Web.config file for an ASP.NET application. It specifies the application's SqlMembershipProvider instance and sets the 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>
