Exception during initialization of a CodeRefactoringProvider when trying to import DTE

问题 I am building a custom code refactoring provider as an extension to Visual Studio 2017 and I want it to access the DTE service. To get it I use the ImportingConstructorAttribute and declare the service a parameter: [ExportCodeRefactoringProvider( LanguageNames.CSharp, Name = nameof( MyCodeRefactoringProvider ) )] [Shared] internal class MyCodeRefactoringProvider : CodeRefactoringProvider { private readonly DTE m_dte; [ImportingConstructor] public MyCodeRefactoringProvider( DTE dte ) { m_dte =

C# WCF plugin design and implementation

由 南楼画角 提交于 2020-01-22 19:48:14
问题 I would like to get some advice. I am developing a system that will load up plugins at runtime and require them to be available through a WCF endpoint. I will have a MVC 3 Web app that is only really used for configuration, and a class library (core) that will load up different plugins. I would appreciate some guidance on how to go about this. I would like to load the plugin up and then be able to create a WCF endpoint that is registered with IIS 7 for access into that plugin. Thanks in

CompositionContractMismatchException when trying to use MEF with MVC controller

由 ≯℡__Kan透↙ 提交于 2020-01-19 12:44:48
问题 I'm working on a bigger C# MVC 4 project which is divided in several assemblies (Core, Domain, Backend MVC, Frontend MVC etc.). I use the plugin architecture provided by MEF to load and resolve most dependencies. Now I also wanted it to use to load MVC controller. Typical scenario found in dozens of samples. But I keep getting this YSOD: The exception says: [CompositionContractMismatchException: Cannot cast the underlying exported value of type "XY.HomeController (ContractName="XY

MEF error, was circular dependency and is now something else

由 故事扮演 提交于 2020-01-13 12:06:54
问题 I've got a circular dependency that recently came about because of a change in my application architecture. The application relies on a plugin manager that loads plugins via MEF. Everything up until worked fine, because it looked something like this: // model.cs [Export("Model")] public class Model { public PluginManager PM { get; set; } [ImportingConstructor] public Model( [Import] PluginManager plugin_manager) { PM = plugin_manager; } } // pluginmanager.cs [Export(typeof(PluginManager))]

MEF ComposeParts. How to handle plugin exceptions

由 独自空忆成欢 提交于 2020-01-13 11:26:46
问题 I have searched on the web for a solution, but I didn't find anything. In my C# application I am using MEF for implementing a plugin pattern. Everything is working fine. However today I have tried to figure out what happens if a Plugin Constructor throws an Exception for some reason. To load plugins I am using CompositionContainer.ComposeParts . If for some reason one of the X plugins throws an exception this method will fail and nothing will be loaded. Is there a way to just catch the single
