新的ASP.NET MVC 4項目異常

我創建了一個新的aspx MVC 4項目。我在默認的MVC 4模板上創建了一些新文件。但是，現在，當我在系統中單擊「註冊」時，我收到一個異常。我沒有改變任何註冊表，只是增加了一些意見。我得到的例外如下所示。有誰知道如何解決這一問題？非常感謝，新的ASP.NET MVC 4項目異常

似乎有一個映射錯誤。檢查您的'CompanyType'和'Company'entities。 –

消息=實體類型'CompanyType'和'Company'不能共享表'Company'，因爲它們不在同一類型層次結構中，或者不具有有效的一對一外鍵關係，並且它們之間具有匹配的主鍵。 <== errormessage指向Thiago的評論 – Stephen

@Stephen謝謝！所以這是我的表的數據庫問題，或與我的文件有問題？ –

我有同樣的問題。我通過啓用和運行我的SQL Server服務來解決它。在開始菜單中：鍵入services>按回車鍵>找到SQL Server（SQLExpress）>右鍵單擊>單擊屬性>如果啓動類型被禁用，切換到自動或手動>點擊開始

希望這會有所幫助。

非常感謝沉默。但這不是問題。 datavase已經啓動並正在運行，但是我把它與我的代碼搞混了。再次感謝。 –
