问题
I am trying to use MSBuild to build a solution with a specified target platform (I need both binaries, x86 and x64). This is how I tried it:
C:\WINDOWS\Microsoft.NET\Framework\v3.5>MsBuild SolutionPath\Solution.sln /t:Rebuild /p:Configuration=Release /p:Platform="x86"
However the build always fails if the platform is different from "Any CPU". What am I doing wrong?
This is the while output MSBuild prints:
C:\WINDOWS\Microsoft.NET\Framework\v3.5>MsBuild SolutionPath\Solution.sln /t:Rebuild /p:Configuration=Release /p:Platform="x86" Microsoft (R) Build Engine Version 3.5.30729.1 [Microsoft .NET Framework, Version 2.0.50727.3082] Copyright (C) Microsoft Corporation 2007. All rights reserved.

If I try to build it for x86/x64 with devenv it works perfectly, however I am trying to set up a build server without installing all the necessary versions of Visual Studio. By the way, if there is a better free tool (that supports .NET framework 4) out there, I'd love to hear about it.
回答1:
If you want to build your solution for x86 and x64, your solution must be configured for both platforms. Actually you just have an Any CPU configuration.
How to check the available configuration for a project
To check the available configuration for a given project, open the project file (*.csproj for example) and look for a PropertyGroup with the right Condition.
If you want to build in Release mode for x86, you must have something like this in your project file:
<PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'Release|x86' ">
...
</PropertyGroup>

In MSBuild or Teamcity use command line
MSBuild yourproject.sln /property:Configuration=Release /property:Platform=x64
or use shorter form:
MSBuild yourproject.sln /p:Configuration=Release /p:Platform=x64
However you need to set up platform in your project anyway, see the answer by Julien Hoarau.

If you're trying to do this from the command line, you may be encountering an issue where a machine-wide environment variable 'Platform' is being set for you and working against you. I can reproduce this if I use the VS2012 Command window instead of a regular windows Command window.
At the command prompt type:
set platform
In a VS2012 Command window, I have a value of 'X64' preset. That seems to interfere with whatever is in my solution file.
In a regular Command window, the 'set' command results in a "variable not defined" message...which is good.
If the result of your 'set' command above returns no environment variable value, you should be good to go.
