Error_5:找不到“Async”修饰符所需的所有类型。 [英] Error_5: Cannot find all types required by the 'Async' modifier.
问题描述
大家好,
我正在尝试在VS Professional 2013(v12.0.40629.00 Update 5)中创建一个VB.NET项目.NET framework 4.5。我需要使用
SDK 用于项目中的IP摄像机。我很好,除非我使用async-await关键字,在使用关键工作后我得到Error_5:找不到'Async'修饰符所需的所有类型。
然而,这不是C#项目的情况,它使用async和await工作正常。
任何提示?
很难说没有显示任何代码。
Hi everyone,
I'm trying to create a VB.NET project in VS Professional 2013(v12.0.40629.00 Update 5) targetting .NET framework 4.5. I need to use a
SDK for IP cameras in the project. I'm fine unless I use async-await keywords, after using the key works I'm getting Error_5: Cannot find all types required by the 'Async' modifier.
However this is not the case with C# project, it works fine with the use of async and await.
Any hints?
Hard to say as no code is being shown.
