"An unexpected error ocurred" CRM 2015 本地插件

Question

2 周以来，我们一直在使用 CRM 2015 OnPremise 中的插件遇到一个完全随机的小问题。当我们进行上传时，随机且没有多大意义（至少根据分析所有代码没有）插件向我们抛出以下异常：

这让人有点头疼，因为我们不明白发生了什么，只是有时会失败，有时不会...我们有一个自定义库注册插件（磁盘）"SCM.Core.dll"，它说自己无法访问...有什么想法吗？

我是 Alexis 的同事，感谢 cardiagtool，现在我们有了更多的细节：

System.IO.FileLoadException: Microsoft Dynamics CRM has experienced an error. Reference number for administrators or support: #ED0C936C: System.IO.FileLoadException: Could not load file or assembly 'SCM.CRM.Core, Version=1.0.0.0, Culture=neutral, PublicKeyToken=369abd01f82b8d9d' or one of its dependencies. Access is denied. File name: 'SCM.CRM.Core, Version=1.0.0.0, Culture=neutral, PublicKeyToken=369abd01f82b8d9d'

Answer 2

正如@Sxntk 所说，如果您在注册插件程序集时使用沙盒模式隔离模式，则需要确保将任何插件与 ilmerge 合并。

如果您的隔离模式为 'none'，请确保该程序集位于 GAC 中或位于服务器上 CRM 安装目录的 bin\assembly 文件夹中。

希望这对您有所帮助。

您可以执行以下操作：

确保所有引用的程序集都将 "Copy Local" 设置为 "True"
从 visual studio
右键单击卸载的项目并编辑 csproj 文件
在 csproj 文件中的 "Project" 结束标记之前（文档最后一行之前）添加以下行：

    <Target Name="AfterResolveReferences">
        <ItemGroup>
          <EmbeddedResource Include="@(ReferenceCopyLocalPaths)" Condition="'%(ReferenceCopyLocalPaths.Extension)' == '.dll'">
            <LogicalName>%(ReferenceCopyLocalPaths.DestinationSubDirectory)%(ReferenceCopyLocalPaths.Filename)%(ReferenceCopyLocalPaths.Extension)</LogicalName>
          </EmbeddedResource>
        </ItemGroup>
      </Target>

将此方法添加到插件中class:

private static Assembly OnResolveAssembly(object sender, ResolveEventArgs args)
{

    Assembly executingAssembly = Assembly.GetExecutingAssembly();
    AssemblyName assemblyName = new AssemblyName(args.Name);
    string path = assemblyName.Name + ".dll";

    if (assemblyName.CultureInfo.Equals(CultureInfo.InvariantCulture) == false)
    {
        path = String.Format(@"{0}\{1}", assemblyName.CultureInfo, path);
    }

    using (Stream stream = executingAssembly.GetManifestResourceStream(path))
    {
        if (stream == null)
            return null;
        byte[] assemblyRawBytes = new byte[stream.Length];
        stream.Read(assemblyRawBytes, 0, assemblyRawBytes.Length);
        return Assembly.Load(assemblyRawBytes);
    }
}

将以下构造函数添加到插件 class：

static [Constructor name]()
{
    AppDomain.CurrentDomain.AssemblyResolve += OnResolveAssembly;
}

重建并注册您的插件

这样做，所有复制到本地 bin 文件夹的引用程序集都打包到主 dll 中。缺点是您最终可能会拥有如此庞大的 dll，以至于您无法将其注册为插件。

希望这对您有所帮助，干杯
