1.新建Class Library(Windows Phone Silverlight)项目

2.找到新建项目的.csproj文件,用记事本打开。找到第一个PropertyGroup节点,在节点中加入

<MonoGamePlatform>WindowsPhone8</MonoGamePlatform>

3.找到Import节点用下面代码替换掉

<ItemGroup>
    <!-- A reference to the entire .Net Framework and Windows SDK are automatically included -->
    <Reference Include="MonoGame.Framework" Condition=" '$(Platform)' == 'ARM' ">
      <HintPath>$(MSBuildProgramFiles32)\MonoGame\v3.0\Assemblies\WindowsPhone\ARM\MonoGame.Framework.dll</HintPath>
    </Reference>
    <Reference Include="MonoGame.Framework" Condition=" '$(Platform)' == 'x86' ">
      <HintPath>$(MSBuildProgramFiles32)\MonoGame\v3.0\Assemblies\WindowsPhone\x86\MonoGame.Framework.dll</HintPath>
    </Reference>
  </ItemGroup>
  <Import Project="$(MSBuildExtensionsPath)\Microsoft\$(TargetFrameworkIdentifier)\$(TargetFrameworkVersion)\Microsoft.$(TargetFrameworkIdentifier).$(TargetFrameworkVersion).Overrides.targets" />
  <Import Project="$(MSBuildExtensionsPath)\Microsoft\$(TargetFrameworkIdentifier)\$(TargetFrameworkVersion)\Microsoft.$(TargetFrameworkIdentifier).CSharp.targets" />

4.在Import节点后面加入

<Target Name="MonoGame_RemoveXnaAssemblies" AfterTargets="ImplicitlyExpandTargetFramework">
<Message Text="MonoGame - Removing XNA Assembly references!" Importance="normal" />
<ItemGroup>
<ReferencePath Remove="@(ReferencePath)" Condition="'%(Filename)%(Extension)'=='Microsoft.Xna.Framework.dll'" />
<ReferencePath Remove="@(ReferencePath)" Condition="'%(Filename)%(Extension)'=='Microsoft.Xna.Framework.GamerServices.dll'" />
<ReferencePath Remove="@(ReferencePath)" Condition="'%(Filename)%(Extension)'=='Microsoft.Xna.Framework.GamerServicesExtensions.dll'" />
<ReferencePath Remove="@(ReferencePath)" Condition="'%(Filename)%(Extension)'=='Microsoft.Xna.Framework.Input.Touch.dll'" />
<ReferencePath Remove="@(ReferencePath)" Condition="'%(Filename)%(Extension)'=='Microsoft.Xna.Framework.MediaLibraryExtensions.dll'" />
</ItemGroup>
</Target>
