How do I specify the platform for MSBuild?

Solution 1:

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.

Solution 2:

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>
