Microsoft.Diagnostics.Tracing.EventSource with the RabbitMQ.Client.dll exception
问题 Why may I be getting the following error and how could I fix it? An unhandled exception of type 'System.IO.FileLoadException' occurred in RabbitMQ.Client.dll Could not load file or assembly 'Microsoft.Diagnostics.Tracing.EventSource, Version=1.1.28.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies.

Trying to bind configuration: System.ComponentModel.TypeConverter can't be loaded
问题 I am trying to use ASP.NET Core configuration (specifically Microsoft.Extensions.Configuration.Json) in a console application. When I call IConfigurationRoot.Bind() it throws a FileNotFound exception for the assembly System.ComponentModel.TypeConverter . To my knowledge TypeConverter is in the System.ComponentModel namespaces in the System assembly, not the fictitious System.ComponentModel.TypeConverter assembly. This appears to be a bug. Or am I missing something? I'm targeting .NET 4.5.2,
Load assembly from memory
问题 I am porting a Java application where classes are loaded and "executed" at runtime from memory (a byte array). I am trying to achieve the same thing in C#, but I am having problems ( System.IO.FileNotFoundException exceptions) when trying to load assemblies from byte arrays (using the AppDomain.Load method). static void Main(string[] args) { var domain = AppDomain.CreateDomain("foo"); domain.AssemblyResolve += new ResolveEventHandler(domain_AssemblyResolve); var assembly = domain.Load(

Why am I getting a MissingMethodException when calling F# code from PowerShell?
问题 I'm trying to use PowerShell to call some F# code which uses Akka.Net actors. The F# code works fine in unit testing and when run from the F# interpreter, but when I call the same code from a PowerShell cmdlet I get the following exception: System.MissingMethodException: Method not found: 'Void Nessos.FsPickler.BinarySerializer..ctor(Microsoft.FSharp.Core.FSharpOption`1<Boolean>, Microsoft.FSharp.Core.FSharpOption`1<Nessos.FsPickler.ITypeNameConverter>)'. at Akka.FSharp.Serialization
Activator.CreateInstance: Could not load type from assembly

Loading an assembly targeted for .NET 4.5 on a .NET 4.0 app domain
Assuming the system has .NET 4.0 and .NET 4.5 installed. Is it possible to load and work with a .NET 4.5 assembly from an assembly written targeting .NET 4.0? Simply put, can I call Assembly.Load from .NET 4.0 code to load a .NET 4.5 targeting assembly? Assuming a system as .NET 4.0 and .NET 4.5: As stated in marcgravell's blog linked by sehe 4.5 is an in-place over-the-top install on top of 4.0, in the GAC; once you have installed 4.5, 4.0 runs with the 4.5 assemblies Then calling Assembly.Load from a .NET code targeting 4.0 (compiled by a 4.0 compiler), will actually run in using the 4.5
