visual studio code not recognizing html files

Question

VS code has suddenly stopped recognizing html files (the file icon is the default one for files with no extension)

all other file extensions work just fine

except for html

the tags still work but it won't autocomplete

Answer 1

Adding this to file extensions worked for me:

"files.associations": {
        "*.html": "html"  
} 

Answer 2

In my case, for this problem the solution was to manually add *.html to files.associations, in user settings. Its unlogical but it seems that somehow the extension wasn't associated to the type of file. Now everything works perfectly...
