【问题描述】：

得到错误：

"The specified task executable "sgen.exe" could not be run. The filename or extension is too long F:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\MSBuild\15.0\Bin\Microsoft.Common.CurrentVersion.targets   3408"

和警告：

"The command-line for the "SGen" task is too long. Command-lines longer than 32000 characters are likely to fail. Try reducing the length of the command-line by breaking down the call to "SGen" into multiple calls with fewer parameters per call.   DAYAnalytics    F:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\MSBuild\15.0\Bin\Microsoft.Common.CurrentVersion.targets 3408"

在 Microsoft.Common.CurrentVersion.targets 的这一部分：

<SGen
    BuildAssemblyName="$(TargetFileName)"
    BuildAssemblyPath="$(IntermediateOutputPath)"
    References="@(ReferencePath)"
    ShouldGenerateSerializer="$(SGenShouldGenerateSerializer)"
    UseProxyTypes="$(SGenUseProxyTypes)"
    UseKeep="$(SGenUseKeep)"
    KeyContainer="$(KeyContainerName)"
    KeyFile="$(KeyOriginatorFile)"
    DelaySign="$(DelaySign)"
    ToolPath="$(SGenToolPath)"
    SdkToolsPath="$(TargetFrameworkSDKToolsDirectory)"
    EnvironmentVariables="$(SGenEnvironment)"
    MSBuildArchitecture="$(SGenMSBuildArchitecture)"
    SerializationAssembly="$(IntermediateOutputPath)$(_SGenDllName)"
    Platform="$(SGenPlatformTarget)"
    Types="$(SGenSerializationTypes)">

解释很简单，但我不明白如何解决它。如何减少命令行长度？

【解决方案1】：

将构建选项中的“生成序列化程序集”选项设置为“自动”或“关闭”，除非您需要它们（即您大量使用 XmlSerializer），在这种情况下您会找到更多信息这里：Generating an Xml Serialization assembly as part of my build
