使用PCL“TPL Dataflow”的项目在编写.NET 4.5.2时无法编译(Project using PCL 'TPL Dataflow' won't compi

使用PCL“TPL Dataflow”的项目在编写.NET 4.5.2时无法编译(Project using PCL 'TPL Dataflow' won't compile when targetting .NET 4.5.2)

我正在使用Windows 7 Pro x64 SP1和Visual Studio 2012 Update 4.在使用TPL Dataflow包和.NET 4.5.2时，我无法编译我的VB.NET WPF项目。 我创建了一个除了这段代码之外什么都没有的基础项目，只为x64编译：

Imports System.Threading.Tasks.Dataflow Class MainWindow Dim test As New System.Threading.Tasks.Dataflow.BufferBlock(Of String) End Class

我已经尝试添加Facical引用到System.Runtime.dll和System.Diagnostics.Tracing.dll没有任何效果。 如果我改为.NET 4.5，它编译得很好。 我必须引用4.5.2，因为项目中需要它的其他功能。

具体错误：

解：

事实证明，我使用的Microsoft .NET Framework 4.5.2开发人员包有一个不允许PCL正确编译的错误。

我从http://support.microsoft.com/kb/2901951下载并安装了Microsoft .NET Framework 4.5.2 Developer Pack的更新版本，我的应用程序能够无错误地编译。

I'm using Windows 7 Pro x64 SP1 and Visual Studio 2012 Update 4. I can't get my VB.NET WPF project to compile when using the TPL Dataflow package and .NET 4.5.2. I've created a base project with nothing except this code and compile only for x64:

Imports System.Threading.Tasks.Dataflow Class MainWindow Dim test As New System.Threading.Tasks.Dataflow.BufferBlock(Of String) End Class

I've tried adding the facade reference to System.Runtime.dll and System.Diagnostics.Tracing.dll with no effect. It compiles fine if I change to .NET 4.5. I must have a reference to 4.5.2 because of other features that will be in the project that require it.

Specific errors:

Solution:

It turns out the Microsoft .NET Framework 4.5.2 Developer Pack I was using had a bug that wouldn't let PCLs compile correctly.

I downloaded and installed the updated version of the Microsoft .NET Framework 4.5.2 Developer Pack from http://support.microsoft.com/kb/2901951 and my application was able to compile without errors.

最满意答案

在连接上有一个票证，指定使用.NET 4.5.2与PCL库导致构建失败。

这已在Microsoft .NET Framework 4.5.2 Developer Pack中修复

当您重新编译使用.NET可移植库来定位Microsoft .NET Framework 4.5.2的Microsoft .NET Framework 4.5.1应用程序时，您在编译期间收到以下错误消息：

类型“{type}”在未引用的程序集中定义。 您必须添加对程序集“{assembly}”的引用

There is a ticket on connect specifying the use of .NET 4.5.2 with PCL libraries causing builds to fail.

This was fixed in the Microsoft .NET Framework 4.5.2 Developer Pack

When you recompile a Microsoft .NET Framework 4.5.1 application that uses .NET portable libraries to target the Microsoft .NET Framework 4.5.2, you receive the following error message during compilation:

The type '{type}' is defined in an assembly that is not referenced. You must add a reference to assembly '{assembly}'
