Question

我使用以下代码行初始化MEF容器

       _mefContainer = new CompositionContainer(
                     new AggregateCatalog(
                     AssemblySource.Instance
                    .Select(x => new AssemblyCatalog(x))
                    .Where(AssemblyFilter)
                    .OfType<System.ComponentModel.Composition.Primitives.ComposablePartCatalog()));

        var batch = new CompositionBatch();
        batch.AddExportedValue<IWindowManager>(new WindowManager());
        batch.AddExportedValue<IEventAggregator>(new EventAggregator());
        batch.AddExportedValue(_mefContainer);

        OnConfigure(batch);

        _mefContainer.Compose(batch);

所有Parts属于一个Assembly - 没有任何依赖！

当我在调试模式下运行应用程序时，一切都进入了墙，

但是，当我切换到发布模式时，我会在代码行中获得CompositionException

string contract = string.IsNullOrEmpty(key) ?  AttributedModelServices.GetContractName(serviceType) : key;
var exports = _mefContainer.GetExportedValues<object>(contract);

我意识到当我尝试对这一行进行双重调用时，我第一次调用方法（从Watch窗口）我得到CompositionException但是第二次它运行了...

修改

以下是AssemblySource.Instance的样子：

很想得到你的帮助。

所以，我发现了问题。这完全是奇怪的..

该应用程序使用NLog作为日志记录框架。

我为每个环境分配了nlog配置（使用来自http://sedodream.com/的XML转换）

在app.config.realese中我设置了nlog属性throwExceptions=false以及该错误的原因！

我说完全很奇怪..？

由于

MEF - 发布模式下的合成错误，但不在调试模式下
