因此​​，原来，新模板不包括ApplicationOAuthProvider的功能实现，在旧模板present。

So it turns out that the new templates don't include a functional implementation of ApplicationOAuthProvider that was present in the older templates.

此版本谈话之后，我进一步调查后发现， ApplicationOAuthProvider的工作实施提供这个包的NuGet ！它非常类似于旧的实现。

After watching this build talk, I investigated further and found that a working implementation of ApplicationOAuthProvider is available to check out in this NuGet package! It's very similar to the old implementation.
