I have writen below code:

var nsmgr = new XmlNamespaceManager(new NameTable());
nsmgr.AddNamespace("asmv1", "urn:schemas-microsoft-com:asm.v1");
xpath = "//asmv1:assembly/dependency/dependentAssembly/assemblyIdentity[name='ImageListView']";
XElement ele = doc.XPathSelectElement(xpath, nsmgr);
ele.Remove();

Your XML has default namespace here : 

<asmv1:assembly 
    ......
    xmlns="urn:schemas-microsoft-com:asm.v2" 
    ......>

Therefore, all XML element without prefix considered in default namespace. You need to add prefix that point to default namespace URI, and use it in XPath :

var nsmgr = new XmlNamespaceManager(new NameTable());
nsmgr.AddNamespace("asmv1", "urn:schemas-microsoft-com:asm.v1");
nsmgr.AddNamespace("d", "urn:schemas-microsoft-com:asm.v2");
xpath = "//asmv1:assembly/d:dependency/d:dependentAssembly/d:assemblyIdentity[@name='ImageListView']";
XElement ele = doc.XPathSelectElement(xpath, nsmgr);
ele.Remove();

UPDATE :

fixed the XPath slightly. You need to use @ to point to attribute : ... [@name='ImageListView']
