Unity代码剥离为High，代码剥离，但我们遇到了 Addressables 包的问题。由于使用反射，ProviderOperation 被剥离。导致ResourceManagerRuntimeData为空

大概报错如下：

解决方案：

在Assets文件夹里面添加 link.xml文件，内容如下：

 
<linker>
    <assembly fullname="Unity.ResourceManager, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null" preserve="all">
    <type fullname="UnityEngine.ResourceManagement.ResourceProviders.LegacyResourcesProvider" preserve="all" />
    <type fullname="UnityEngine.ResourceManagement.ResourceProviders.AssetBundleProvider" preserve="all" />
    <type fullname="UnityEngine.ResourceManagement.ResourceProviders.BundledAssetProvider" preserve="all" />
    <type fullname="UnityEngine.ResourceManagement.ResourceProviders.InstanceProvider" preserve="all" />
    <type fullname="UnityEngine.ResourceManagement.AsyncOperations" preserve="all" />
    </assembly>
    <assembly fullname="Unity.Addressables, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null" preserve="all">
    <type fullname="UnityEngine.AddressableAssets.Addressables" preserve="all" />
    </assembly>
</linker>

如果项目中已经存在link.xml文件，直接在link.xml文件中追加以下内容即可：

<assembly fullname="Unity.ResourceManager, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null" preserve="all">
    <type fullname="UnityEngine.ResourceManagement.ResourceProviders.LegacyResourcesProvider" preserve="all" />
    <type fullname="UnityEngine.ResourceManagement.ResourceProviders.AssetBundleProvider" preserve="all" />
    <type fullname="UnityEngine.ResourceManagement.ResourceProviders.BundledAssetProvider" preserve="all" />
    <type fullname="UnityEngine.ResourceManagement.ResourceProviders.InstanceProvider" preserve="all" />
    <type fullname="UnityEngine.ResourceManagement.AsyncOperations" preserve="all" />
    </assembly>
    <assembly fullname="Unity.Addressables, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null" preserve="all">
    <type fullname="UnityEngine.AddressableAssets.Addressables" preserve="all" />
    </assembly>
