Microsoft .NET UriTypeConverter relative or absolute URI ConfigurationBinder GetValue Uri documentation

💡 Result:

The.NET ConfigurationBinder.GetValue method supports binding to System.Uri properties by utilizing the TypeConverter mechanism [1][2]. When you use ConfigurationBinder to retrieve a configuration value as a Uri, the system internally employs UriTypeConverter to convert the configuration's string value into a Uri instance [3][2]. Regarding the handling of relative versus absolute URIs: 1. UriTypeConverter Behavior: The UriTypeConverter is responsible for string-to-Uri conversion [3]. While it generally handles standard URI strings well, its ability to distinguish or enforce URI types (relative vs. absolute) is governed by the underlying System.Uri class logic [4][5]. 2. Limitations with Relative URIs: In historical.NET versions, there have been identified gaps where UriTypeConverter did not consistently handle certain relative URI scenarios during conversion [6]. If your configuration contains a relative URI, ensure that the application logic consuming the resulting Uri instance is prepared to handle it (e.g., by resolving it against a base URI if necessary), as the Uri class itself distinguishes between relative and absolute instances based on its constructor or static factory methods (e.g., TryCreate) [4][5]. 3. ConfigurationBinder Mechanism: ConfigurationBinder does not natively provide a way to specify UriKind (Absolute vs. Relative) during the GetValue call [7][8]. It performs a standard type conversion [1]. If you require specific enforcement (e.g., ensuring a configuration value is an absolute URI), you should retrieve the value as a string first, validate it using Uri.TryCreate with the desired UriKind, and then instantiate the Uri object [4][5]. In summary, while ConfigurationBinder automatically converts configuration strings to Uri objects using UriTypeConverter, it does not offer built-in configuration settings to mandate that a URI must be absolute or relative [1][2]. For critical applications requiring strict URI validation, manual parsing using Uri.TryCreate is recommended [4].

Validate BaseUrl as an absolute HTTP(S) URI.

RegisterFrontendOptions does not enforce IsAbsoluteUri or an http/https scheme. CookieSecure returns false for every other scheme, so an invalid production configuration can emit authentication cookies without Secure.
