ERROR: @angular/material/material has no exported member 'MdButtonModule'

Question

Error below arose after upgrading from @angular/material 2.0.0-beta.11 to 2.0.0-beta.12:

Module @angular/material/material has no exported member 'MdButtonModule'.

Typescript-code:

import { MdButtonModule } from '@angular/material';

What happened?

You have to include MatButtonModule instead of MdButtonModule. You will also have to update the prefix in your template i.e. md-button should now be mat-button. To update the prefix in your entire app, follow the guidelines in this Prefix Updater.

Since 2.0.0-beta.12 the Md prefix has been removed and you should use Mat prefix everywhere. From the CHANGELOG of 2.0.0-beta.11:

For beta.11, we've made the decision to deprecate the "md" prefix completely and use "mat" moving forward. This affects all class names, properties, inputs, outputs, and selectors (CSS classes were changed back in February). The "md" prefixes will be removed in the next beta release.

And from the CHANGELOG of 2.0.0-beta.12:

Breaking Changes All "md" prefixes have been removed.

See this working StackBlitz demo with individual material modules and using Mat prefix.
