DllExportAppDomainIsolatedTask 在构建 DLL 时意外失败

Question

我正在尝试在 Visual Studio 中用 C# 构建 Dll。使用 NuGet RGiesecke.DllExport。然而，由于某种原因，它在构建 Dll 时返回一些错误。下面是描述。

错误
“DllExportAppDomainIsolatedTask”任务意外失败。System.ArgumentException：找不到请求的值“Version46”。

我安装了 Microsoft Build Tools 2015，这解决了我的问题。

Answer 2

这是一个关于DllExport包的问题。

在 VS2017 中编译失败---问题 #29 Error The "DllExportAppDomainIsolatedTask" task failed unexpectedly. System.ArgumentException: Requested value 'Version46' was not found.

您可以看看这个类似的问题，您应该使用更高版本的DllExport nuget 包。（至少 1.5.2）。
