Hi,
i used this code
@font-face{
font-family: 'Open Sans';
font-style: normal;
font-weight: 400;
src: url('/<your directory>/OpenSans.GoogleFonts.css')
}
@font-face {
font-family: 'Material Icons';
font-style: normal;
font-weight: 400;
src: url('/<your directory> /MaterialIcons-Regular.eot'); /* For IE6-8 */
src: local('Material Icons'),
local('MaterialIcons-Regular'),
url('/<your directory> /MaterialIcons-Regular.woff2') format('woff2'),
url('/<your directory> /MaterialIcons-Regular.woff') format('woff'),
url('/<your directory> /MaterialIcons-Regular.ttf') format('truetype');
}
.material-icons {
font-family: 'Material Icons';
font-weight: normal;
font-style: normal;
font-size: 24px; /* Preferred icon size */
display: inline-block;
line-height: 1;
text-transform: none;
letter-spacing: normal;
word-wrap: normal;
white-space: nowrap;
direction: ltr;
/* Support for all WebKit browsers. */
-webkit-font-smoothing: antialiased;
/* Support for Safari and Chrome. */
text-rendering: optimizeLegibility;
/* Support for Firefox. */
-moz-osx-font-smoothing: grayscale;
/* Support for IE. */
font-feature-settings: 'liga';
}
/* Rules for sizing the icon. */
.material-icons.md-18 { font-size: 18px; }
.material-icons.md-24 { font-size: 24px; }
.material-icons.md-36 { font-size: 36px; }
.material-icons.md-48 { font-size: 48px; }
.material-icons.md-64 { font-size: 64px; }
/* Rules for using icons as black on a light background. */
.material-icons.md-primary { color: var(--color-primary); }
.material-icons.md-dark { color: rgba(0, 0, 0, 0.54); }
.material-icons.md-dark.md-inactive { color: rgba(0, 0, 0, 0.26); }
/* Rules for using icons as white on a dark background. */
.material-icons.md-light { color: rgba(255, 255, 255, 1); }
.material-icons.md-light.md-inactive { color: rgba(255, 255, 255, 0.3); }

All the resources as Deploy to Target Directory.
And i used a html tag with a expression

Class = 'material-icons'
On the expression the value is the icon name. E.g: home
