c# - Why does R# warn me about a commented-out line in CSHTML? -

r# tells me "possible 'system.nullreferenceexception'" on line commented out:

// report_params = { guid: @model.guid, serialnumber: @model.serialnumber, reportname: @model.reportname };  

the light bulb "agent" has options "check if model not null" , "assert model not null"

why resharper examine commented-out code? yet, following live code, gets unscathed:

report_params = {     guid: "@model.guid",     serialnumber: "@model.serialnumber",     reportname: "@model.reportname" }; 

although quotes around vals wrong me.

update

r# telling me, "unknown css class 'staticlabel'" line of html:

<label for="begindate" class="staticlabel">begin date</label> 

...when have, in same .cshtml file, in section:

.staticlabel {     display: inline-block;     width: 140px;     margin-right: 2px;     text-align: right;     font-family: consolas, candara, sans-serif;     font-weight: bold;      color: brown; } 

(it's not complaining other classes there supposedly being unknown)

update 2

i had "unmatched closing tag" ( duplicated, rogue rapscallion hidden way out @ line 486).
