我编写了一个使用实体框架的项目，并且在本地运行良好。但是当我尝试使用 VSTS 运行自动构建时，运行构建定义时出现错误。我知道它是由实体框架引用引起的，但我无法找到根本原因。这是构建错误以供参考。

问题出在您在 .csproject 中的引用中，它使用本地引用（它取自硬盘中的 packages 文件夹）。显然，当部署在服务器中时，这将不起作用。将其更改为 nugetpackages 路径。以我在下面给出的格式更改所有引用的提示路径

$(NugetPackagesPath)\EntityFramework.6.1.1\lib\net45\Entity‌​Framework.dll

您可以使用以下定义 NugetPackagesPath 的代码

<PropertyGroup>
    <!-- EnlistmentRoot is the base directory where all of the module root directories reside. --> 
    <EnlistmentRoot>$(MSBuildThisFileDirectory)</EnlistmentRoot>
    <EnlistmentRoot Condition="'$(EnlistmentRoot)' != ''">$([System.IO.Path]::GetFullPath('$(EnlistmentRoot)'))</EnlistmentRoot>
    <EnlistmentRoot Condition="'$(EnlistmentRoot)' != '' and !HasTrailingSlash('$(EnlistmentRoot)')">$(EnlistmentRoot)\</EnlistmentRoot>
</PropertyGroup>
<PropertyGroup>
    <!-- NuGetPackagesPath is the base directory for all nuget packages. --> 
    <NuGetPackagesPath>$(EnlistmentRoot)Ref\Packages</NuGetPackagesPath>
    <NuGetPackagesPath Condition="'$(NuGetPackagesPath)' != ''">$([System.IO.Path]::GetFullPath('$(NuGetPackagesPath)'))</NuGetPackagesPath>
    <NuGetPackagesPath Condition="'$(NuGetPackagesPath)' != '' and !HasTrailingSlash('$(NuGetPackagesPath)')">$(NuGetPackagesPath)\</NuGetPackagesPath>
</PropertyGroup>
