无法在解决方案中调试项目

找出问题...在网上看到许多这类问题...请确保如果您要调试的是VSTO插件或类似应用程序，而您自己没有手动加载程序集，则这会为vs.net调试器，并使附属程序集不可调试。以下是违规代码的示例：

            var assemblyInfo = Assembly.GetExecutingAssembly();

            var uriCodeBase = new Uri(assemblyInfo.CodeBase);
            var clickOnceLocation = Path.GetDirectoryName(uriCodeBase.LocalPath);
            // find all simple injector packages
            var packages = (from file in new DirectoryInfo(clickOnceLocation).GetFiles()
                            where file.Extension == ".dll" && file.Name.ToLowerInvariant() != "myaddin.core.dll" &&
                            file.Name.StartsWith("MyAddin")
                            select Assembly.LoadFile(file.FullName)).ToList();
