私は既存のMVCプロジェクトにアップショットの良さを追加しようとしています。

ライン上

@(Html.UpshotContext().DataSource<DataServiceController>(x => x.GetAllProducts()))

例外が発生します

Googleはその例外について何も教えてくれません。何か案は？

このスレッドの議論に従って: 現在の SPA (ベータ版) は MVC 4 RC と互換性がありません

ASP.NET チームは、当面は MVC4 ベータ版 + SPA Nuget パッケージを使用することを推奨しています。別の方法としては、競合するライブラリのコードを取得して自分でビルドすることをお勧めしますが、それではチームが前進するにつれて頭痛の種になり、やり直しが必要になります。

NuGetからインストールしてみてください:
