Assembly:

System.ServiceModel.Primitives.dll

Package:

System.ServiceModel.Primitives v8.1.1

Source:

SecurityTokenAuthenticator.cs

When overridden in a derived class, authenticates the specified security token and returns the set of authorization policies for the security token.

C#

protected abstract System.Collections.ObjectModel.ReadOnlyCollection<System.IdentityModel.Policy.IAuthorizationPolicy> ValidateTokenCore(System.IdentityModel.Tokens.SecurityToken token);

Parameters

token

SecurityToken

The SecurityToken to be validated.

Returns

ReadOnlyCollection<IAuthorizationPolicy>

A ReadOnlyCollection<T> of type IAuthorizationPolicy that contains the set of authorization policies in effect for this application.

Remarks

Override the ValidateTokenCore method to authenticate a specific security token type.

When the ValidateTokenCore method is overridden, follow these guidelines:

• When the security token passed into the token parameter cannot be validated, throw a SecurityTokenValidationException exception.

• When there are no authorization policies in effect for this application, return an empty ReadOnlyCollection<T> of type IAuthorizationPolicy.

When this method returns null, Windows Communication Foundation throws a SecurityTokenValidationException exception.

The ValidateTokenCore method is called by the ValidateToken method.
