ASP.NET .NET 4.6 MVC4应用程序加载unnessecary assemblie,eq。 System.Data.OracleClient。不使用Oracle。
使用控制器
中的代码创建程序集依赖项 var sb = new StringBuilder();
foreach (Assembly b in AppDomain.CurrentDomain.GetAssemblies())
{
sb.AppendLine(b.FullName);
foreach (AssemblyName an in b.GetReferencedAssemblies())
sb.AppendLine(" " + an.Name);
}
输出如下。根据这个System.Web引用System.Design和System.Design对System.Data.OracleClient的引用
MVC应用程序在内存有限的VPS服务器中运行。如何解决这个问题,以便不加载unnessecary程序集? 这有望在VPS服务器中释放一些内存。

更新
我试着根据回答将删除命令放到web.config但是出错了
还尝试使用
根据答案删除oracle部分<configuration>
<configSections>
<section name="system.data.oracleclient" type="System.Data.Common.DbProviderConfigurationHandler, System.Data, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089">
<remove name="system.data.oracleclient"></remove>
</section>
</configSections>
...
但得到了错误:
如何解决?
答案 0 :(得分:1)
Web应用程序上有三种程序集。
在前一种情况下,您可以优化您的库,直接在您的dll项目中删除任何不必要的引用。
在第二种情况下,要优化您的网页以及编译什么,您需要删除任何不必要的代码背后的代码...例如,页面通常有第一行
using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
你不使用的是灰色,你可以删除它......
现在困难的部分 - 很难,因为你必须玩“尝试/失败”游戏。现在您可以删除哪些内容。
首先我在哪里搜索以找到要删除的内容...答案是在 asp.net 上的全局web.config上。在我的情况下,我会在配置目录上的配置目录中的 windows 目录中找到web.config
我找到了一些钥匙......
首先,您可以在httpModule
上的web.config
会话中移除不必要的Http模块以加快管道
这是我在全球web.config
上看到的<httpModules>
<add name="OutputCache" type="System.Web.Caching.OutputCacheModule" />
<add name="Session" type="System.Web.SessionState.SessionStateModule" />
<add name="WindowsAuthentication" type="System.Web.Security.WindowsAuthenticationModule" />
<add name="FormsAuthentication" type="System.Web.Security.FormsAuthenticationModule" />
<add name="PassportAuthentication" type="System.Web.Security.PassportAuthenticationModule" />
<add name="RoleManager" type="System.Web.Security.RoleManagerModule" />
<add name="UrlAuthorization" type="System.Web.Security.UrlAuthorizationModule" />
<add name="FileAuthorization" type="System.Web.Security.FileAuthorizationModule" />
<add name="AnonymousIdentification" type="System.Web.Security.AnonymousIdentificationModule" />
<add name="Profile" type="System.Web.Profile.ProfileModule" />
<add name="ErrorHandlerModule" type="System.Web.Mobile.ErrorHandlerModule, System.Web.Mobile, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
<add name="ServiceModel" type="System.ServiceModel.Activation.HttpModule, System.ServiceModel.Activation, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />
<add name="UrlRoutingModule-4.0" type="System.Web.Routing.UrlRoutingModule" />
<add name="ScriptModule-4.0" type="System.Web.Handlers.ScriptModule, System.Web.Extensions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
</httpModules>
我在我的应用程序上转到web.config,这就是我删除我不使用的内容:
<httpModules>
<remove name="Session" />
<remove name="PassportAuthentication" />
<remove name="AnonymousIdentification" />
</httpModules>
现在为你的情况我继续汇编会话,这是我在全球web.config上看到的:

<add assembly="*" />
<add assembly="System.Web.WebPages.Deployment, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />
</assemblies>
这是因为它是我复制/粘贴到我的web.config并在第一行放置<clear />
然后我开始删除我知道我的程序不使用的行...并小心保持这个第<add assembly="*" />
行,最后说这是从你的dll目录添加你的库。
<assemblies>
<clear />
<add assembly="Microsoft.VisualStudio.Web.PageInspector.Loader, Version=1.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
<add assembly="mscorlib" />
<add assembly="Microsoft.CSharp, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
....
<add assembly="*" />
</assemblies>
通过删除并查看您的应用程序是否仍然有效,删除并删除不使用的那个,可以限制您使用的程序集。
我做了一个简单的测试并删除了这一行
<add assembly="System.WorkflowServices, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />
这次我只计算从83下降到79只装配的程序集。为什么不止一个减去?因为WorkflowServices
自己加载了更多。
要从配置部分删除某些内容,请再次在web.config上执行以下操作:
<configuration>
<configSections>
<remove name="system.data.oracleclient"></remove>
...

我的工作站在整个machine.config中都引用了Oracle。我相信你会在那里找到你的流氓参考资料。
