我在VS 2008中有一個C＃項目，每次構建解決方案時都會重建該項目，即使此項目中的任何內容或其任何依賴項都未更改。這造成了一個巨大的問題，因爲解決方案非常大（> 100個項目），而且這個項目在依賴關係鏈上非常低，所以現在大多數其他項目也會重建，因爲沒有重建應該有是必要的。 （我在做「構建解決方案」而不是「重建解決方案」。）我的VS 2008解決方案中的項目每次重建
我知道這個項目是罪魁禍首，因爲我將「MSBuild項目構建輸出冗長」轉變爲「診斷」。然後我構建解決方案兩次，而不更改構建之間的任何內容。在第二個版本中，這是正在重建的解決方案中的第一個項目，正如注意到Csc.exe正在執行一樣。
下面是我在生成輸出看到：
------ Build started: Project: COS.BusinessEntities, Configuration: Debug Any CPU ------
...
Target "CoreCompile" in file "c:\WINDOWS\Microsoft.NET\Framework\v3.5\Microsoft.CSharp.targets":
Building target "CoreCompile" completely.
Output file "bin\Debug\COS.BusinessEntities.XML" does not exist.
Task "Csc"
Command:
c:\WINDOWS\Microsoft.NET\Framework\v3.5\Csc.exe /noconfig /nowarn:1591,1573,0219,0168,1572,1587,1570,1701,1702 /errorreport:prompt /warn:4 /doc:bin\Debug\COS.BusinessEntities.XML /define:DEBUG;TRACE ...
這樣看來，當它到達COS.BusinessEntities項目，它沒有找到的「bin \調試\ COS.BusinessEntities.XML 「文件。但是我已經證實這個文件確實存在於第一次構建之後，並且我不相信它會被刪除並重新創建（但對於如何驗證這一點可以提供建議）。我在嘗試第二次構建時嘗試觀看文件夾，但從未看到它消失。
另一個線索是，這種行爲開始於特定的簽入，其中開發人員向項目添加了兩個文件：一個OptionsEntities.edmx文件和OptionsEntities.Designer.cs。下面也被加入到了COS.BusinessEntities.prj文件：
<Compile Include="Options\Entities\OptionsEntities.Designer.cs">
<AutoGen>True</AutoGen>
<DesignTime>True</DesignTime>
<DependentUpon>OptionsEntities.edmx</DependentUpon>
</Compile>
...
<EntityDeploy Include="Options\Entities\OptionsEntities.edmx">
<Generator>EntityModelCodeGenerator</Generator>
<LastGenOutput>OptionsEntities.Designer.cs</LastGenOutput>
</EntityDeploy>
顯然，這些項目是必要的EDMX文件，但我想知道如果某些值不正確，導致出現此問題。我確信這是罪魁禍首，就像我得到以前的變更集一樣，這個問題就會消失;在沒有代碼更改之後構建解決方案時，項目不會自行重建。
任何幫助表示讚賞！我幾天來一直在絞盡腦汁！
感謝，

編輯： 去除該項目的XML文檔的XML文件後，我仍然得到了同樣的問題，但這裏的新的輸出：
Target "CoreCompile" in file "c:\WINDOWS\Microsoft.NET\Framework\v3.5\Microsoft.CSharp.targets":
Building target "CoreCompile" completely.
Input file "C:\Documents and Settings\<my username>\Local Settings\Temp\tmp6D36.tmp" is newer than output file "obj\Debug\COS.BusinessEntities.pdb".

Command:

...那個臨時文件每次都不一樣！哎呀！現在要做什麼？
編輯2： 以下是編譯輸出的相關部分，與此相關的臨時文件（這些開始BusinessEntities項目內）：
Target "SplitResourcesByCulture" in file "c:\WINDOWS\Microsoft.NET\Framework\v3.5\Microsoft.Common.targets":
Task "Warning" skipped, due to false condition; ('@(ResxWithNoCulture)'!='') was evaluated as (''!='').

Done building target "CreateManifestResourceNames" in project "COS.BusinessEntities.csproj".
再稍加進一步下跌：
Target "_GenerateCompileInputs" in file "c:\WINDOWS\Microsoft.NET\Framework\v3.5\Microsoft.Common.targets":
Task "Warning" skipped, due to false condition; ('@(ManifestResourceWithNoCulture)'!='' and '%(ManifestResourceWithNoCulture.EmittedForCompatibilityOnly)'=='') was evaluated as (''!='' and ''=='').
Task "Warning" skipped, due to false condition; ('@(ManifestNonResxWithNoCultureOnDisk)'!='' and '%(ManifestNonResxWithNoCultureOnDisk.EmittedForCompatibilityOnly)'=='') was evaluated as ('C:\Documents and Settings\<my username>\Local Settings\Temp\tmp6D36.tmp;C:\Documents and Settings\<my username>\Local Settings\Temp\tmp6D38.tmp;C:\Documents and Settings\<my username>\Local Settings\Temp\tmp6D37.tmp'!='' and 'true'=='').
Done building target "_GenerateCompileInputs" in project "COS.BusinessEntities.csproj".
所以它看起來還有其他一些臨時文件，但我不確定它們爲什麼會生成，或者它們爲什麼被視爲項目的輸入。
非常感謝迄今爲止的幫助！
