Syntax

  [out, retval] IAppxManifestReader **manifestReader
);

Parameters

[in] inputStream

Type: IStream*

The input stream that delivers the manifest XML for reading. The stream must support Read, Seek, and Stat. If these methods fail, their error codes might be passed to and returned by this method.

[out, retval] manifestReader

Type: IAppxManifestReader**

The manifest reader.

Return value

Type: HRESULT

If the method succeeds, it returns S_OK. Otherwise, it returns an error code that includes, but is not limited to, those in the following table.

Return code	Description
APPX_E_INVALID_MANIFEST	The inputStream does not contain syntactically valid XML for the manifest.

Remarks

Use CreateManifestReader to read a manifest outside of an app package. This method validates the manifest XML. The manifestReader provides access to all data elements and attributes in the manifest XML. The manifest logs the location of manifest validation errors in the ETW event log for AppxPackaging.
