Hi All,

I have an issue while removing namespace prfix "asmv2". It is throwing null reference exception.

Please see below code snippet:

/// <summary>

  /// Remove lines from the manifest that contain filenames that do not

  /// exist in the addin bin folder

  /// </summary>

  /// <param name="manifest">Manifest file to edit</param>

  private static void SanitizeManifestToMatchBin(string manifest, string addInBinFolder)

  {

     // load manifest

     XDocument xDoc = XDocument.Load(manifest);

     xDoc.Root.Attribute(XNamespace.Xmlns + "asmv2").Remove();

     XNamespace ns = "urn:schemas-microsoft-com:asm.v2";

     // remove any files from dependentAssembly/codebase that do not exist in the bin folder

     xDoc.Descendants(ns + "dependentAssembly")

        .Where(x => (string)x.Attribute("dependencyType") == "install" && File.Exists(addInBinFolder + "\\" + (string)x.Attribute("codebase").Value) == false)

        .Select(x => x.Parent)

        .Remove();

     //xDoc.Descendants(ns + "file")

     //   .Where(x => File.Exists(addInBinFolder + "\\" + (string)x.Attribute("name").Value) == false)

     //   .Select(x => x)

     //   .Remove();

     //xDoc.Descendants(ns + "file").Remove();

     xDoc.Save(manifest);

  }

At above code snippet,

xDoc.Root.Attribute(XNamespace.Xmlns + "asmv2").Remove(); //is throwing null reference exception.

Below is my xml manifest:

<asmv1:assembly xsi:schemaLocation="urn:schemas-microsoft-com:asm.v1 assembly.adaptive.xsd" manifestVersion="1.0"

xmlns:asmv1="urn:schemas-microsoft-com:asm.v1" xmlns="urn:schemas-microsoft-com:asm.v2"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xmlns:co.v1="urn:schemas-microsoft-com:clickonce.v1"

xmlns:asmv3="urn:schemas-microsoft-com:asm.v3"

xmlns:dsig="XML-Signature Syntax and Processing"

xmlns:co.v2="urn:schemas-microsoft-com:clickonce.v2">

In above xml manifest, I found that "asmv2" is not available and I am trying to remove this entry.

Please help me to solve this problem.

Thank you.
