sgen.exe fails during build

Question

After changing the output directory of a visual studio project it started to fail to build with an error very much like:

C:\Program Files\Microsoft Visual Studio 8\SDK\v2.0\bin\sgen.exe /assembly:C:\p4root\Zantaz\trunk\EASDiscovery\EASDiscoveryCaseManagement\obj\Release\EASDiscoveryCaseManagement.dll /proxytypes /reference:C:\p4root\Zantaz\trunk\EASDiscovery\EasDiscovery.Common\target\win_x32\release\results\EASDiscovery.Common.dll /reference:C:\p4root\Zantaz\trunk\EASDiscovery\EasDiscovery.Export\target\win_x32\release\results\EASDiscovery.Export.dll /reference:c:\p4root\Zantaz\trunk\EASDiscovery\ItemCache\target\win_x32\release\results\EasDiscovery.ItemCache.dll /reference:c:\p4root\Zantaz\trunk\EASDiscovery\RetrievalEngine\target\win_x32\release\results\EasDiscovery.RetrievalEngine.dll /reference:C:\p4root\Zantaz\trunk\EASDiscovery\EASDiscoveryJobs\target\win_x32\release\results\EASDiscoveryJobs.dll /reference:"C:\Program Files\Infragistics\NetAdvantage for .NET 2008 Vol. 1 CLR 2.0\Windows Forms\Bin\Infragistics2.Shared.v8.1.dll" /reference:"C:\Program Files\Infragistics\NetAdvantage for .NET 2008 Vol. 1 CLR 2.0\Windows Forms\Bin\Infragistics2.Win.Misc.v8.1.dll" /reference:"C:\Program Files\Infragistics\NetAdvantage for .NET 2008 Vol. 1 CLR 2.0\Windows Forms\Bin\Infragistics2.Win.UltraWinChart.v8.1.dll" /reference:"C:\Program Files\Infragistics\NetAdvantage for .NET 2008 Vol. 1 CLR 2.0\Windows Forms\Bin\Infragistics2.Win.UltraWinDataSource.v8.1.dll" /reference:"C:\Program Files\Infragistics\NetAdvantage for .NET 2008 Vol. 1 CLR 2.0\Windows Forms\Bin\Infragistics2.Win.UltraWinDock.v8.1.dll" /reference:"C:\Program Files\Infragistics\NetAdvantage for .NET 2008 Vol. 1 CLR 2.0\Windows Forms\Bin\Infragistics2.Win.UltraWinEditors.v8.1.dll" /reference:"C:\Program Files\Infragistics\NetAdvantage for .NET 2008 Vol. 1 CLR 2.0\Windows Forms\Bin\Infragistics2.Win.UltraWinGrid.v8.1.dll" /reference:"C:\Program Files\Infragistics\NetAdvantage for .NET 2008 Vol. 1 CLR 2.0\Windows Forms\Bin\Infragistics2.Win.UltraWinListView.v8.1.dll" /reference:"C:\Program Files\Infragistics\NetAdvantage for .NET 2008 Vol. 1 CLR 2.0\Windows Forms\Bin\Infragistics2.Win.UltraWinMaskedEdit.v8.1.dll" /reference:"C:\Program Files\Infragistics\NetAdvantage for .NET 2008 Vol. 1 CLR 2.0\Windows Forms\Bin\Infragistics2.Win.UltraWinStatusBar.v8.1.dll" /reference:"C:\Program Files\Infragistics\NetAdvantage for .NET 2008 Vol. 1 CLR 2.0\Windows Forms\Bin\Infragistics2.Win.UltraWinTabControl.v8.1.dll" /reference:"C:\Program Files\Infragistics\NetAdvantage for .NET 2008 Vol. 1 CLR 2.0\Windows Forms\Bin\Infragistics2.Win.UltraWinToolbars.v8.1.dll" /reference:"C:\Program Files\Infragistics\NetAdvantage for .NET 2008 Vol. 1 CLR 2.0\Windows Forms\Bin\Infragistics2.Win.UltraWinTree.v8.1.dll" /reference:"C:\Program Files\Infragistics\NetAdvantage for .NET 2008 Vol. 1 CLR 2.0\Windows Forms\Bin\Infragistics2.Win.v8.1.dll" /reference:"C:\Program Files\Microsoft Visual Studio 8\ReportViewer\Microsoft.ReportViewer.Common.dll" /reference:"C:\Program Files\Microsoft Visual Studio 8\ReportViewer\Microsoft.ReportViewer.WinForms.dll" /reference:C:\p4root\Zantaz\trunk\EASDiscovery\PreviewControl\target\win_x32\release\results\PreviewControl.dll /reference:C:\p4root\Zantaz\trunk\EASDiscovery\Quartz\src\Quartz\target\win_x32\release\results\Scheduler.dll /reference:c:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\System.configuration.dll /reference:c:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\System.Data.dll /reference:c:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\System.Design.dll /reference:c:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\System.DirectoryServices.dll /reference:c:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\System.dll /reference:c:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\System.Drawing.dll /reference:c:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\System.Web.dll /reference:c:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\System.Web.Services.dll /reference:c:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\System.Windows.Forms.dll /reference:c:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\System.Xml.dll /compiler:/delaysign- 
    Error: The specified module could not be found. (Exception from HRESULT: 0x8007007E)
    C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Microsoft.Common.targets(1902,9): error MSB6006: "sgen.exe" exited with code 1.

I changed the output directory to target/win_x32/release/results but the path in sgen doesn't seem to have been updated. There seems to be no reference in the project to what path is passed into sgen so I'm unsure how to fix it. As a workaround I have disabled the serialization generation but it would be nice to fix the underlying problem. Has anybody else seen this?

Answer 1

If you are having this problem while building your VS.NET project in Release mode here is the solution:

Go to the project properties and click on the Build tab and set the value of the "Generate Serialization Assembly" dropdown to "Off".

Sgen.exe is "The XML Serializer Generator creates an XML serialization assembly for types in a specified assembly in order to improve the startup performance of a XmlSerializer when it serializes or deserializes objects of the specified types." (MSDN)

Answer 2

see msdn for the options to sgen.exe [you have the command line, you can play with it manually... delete your .XmlSerializers.dll or use /force though]

Today I also ran across how to more manually specify the sgen options. I wanted this to not use the /proxy switch, but it appears it can let you specify the output directory. I don't know enough about msbuild to make it awesome, but this should get you started [open your .csproj/.vbproj in your non-visual studio editor of choice, look at the bottom and you should be able to figure out how/where this goes]

[the below code has had UseProxyTypes set to true for your convenience]

<Target Name="GenerateSerializationAssembliesForAllTypes"
  DependsOnTargets="AssignTargetPaths;Compile;ResolveKeySource"
  Inputs="$(MSBuildAllProjects);@(IntermediateAssembly)"
  Outputs="$(OutputPath)$(_SGenDllName)">
    <SGen BuildAssemblyName="$(TargetFileName)"
      BuildAssemblyPath="$(OutputPath)" References="@(ReferencePath)"
      ShouldGenerateSerializer="true" UseProxyTypes="true"
      KeyContainer="$(KeyContainerName)" KeyFile="$(KeyOriginatorFile)"
      DelaySign="$(DelaySign)" ToolPath="$(SGenToolPath)">
        <Output TaskParameter="SerializationAssembly"
          ItemName="SerializationAssembly" />
     </SGen>
</Target>
