How do I dynamically load raw assemblies that contains unmanaged code?(bypassing 'Unverifiable code failed policy check' exception)

烈酒焚心 提交于 2019-12-02 22:32:51
I'm going to give an example of using System.Data.SQLite.DLL which is a mixed assembly with unmanaged code: If I execute this : var assembly= Assembly.LoadFrom("System.Data.SQLite.DLL") No exceptions are thrown, but if I do this : var rawAssembly = File.ReadAllBytes("System.Data.SQLite.DLL"); var assembly = Assembly.Load(rawAssembly); The CLR throws a FileLoadException with "Unverifiable code failed policy check. (Exception from HRESULT: 0x80131402)". Let's say I'm trying to load this assembly on a child AppDomain, how can I customize the AppDomain's security to allow me pass the policy check?

Load assemblies with dependencies in a different AppDomain

问题 My aim is to make a missing dependency check between 2 given folders. Imagine the following setup. Root\DirA\A.dll Root\DirB\B.dll B depends on A. So given these folders, I want to create a new AppDomain, load B.dll and have the dependency from DirA(A.dll) automatically resolved and isolated in that new AppDomain. Isolation is key here given that when I unload this AppDomain I want to create a new one with potentially DirA as a dependency again but DirC libraries that require it so in the

Why is AppDomainSetup.ShadowCopyFiles a string?

我只是一个虾纸丫 提交于 2019-11-30 17:43:27
From the documentation : A String containing the string value "true" to indicate that shadow copying is turned on; or "false" to indicate that shadow copying is turned off. And its been this way since 1.1. Can anyone shed any light? I reflector'd the getter and setter for good measure: public string ShadowCopyFiles { get { return this.Value[8]; } set { if ((value != null) && (string.Compare(value, "true", StringComparison.OrdinalIgnoreCase) == 0)) { this.Value[8] = value; } else { this.Value[8] = null; } } } //The referenced Value property... internal string[] Value { get { if (this._Entries =

What is the right way to set shadow copying for the default AppDomain

怎甘沉沦 提交于 2019-11-30 04:00:27
Relating to Can I make the default AppDomain use shadow copies of certain assemblies? , it describes a working solution to activate shadow copying within the default AppDomain for a specific directory. Basically it says to use these simple methods: AppDomain.CurrentDomain.SetShadowCopyPath(aDirectory); AppDomain.CurrentDomain.SetShadowCopyFiles(); But because the methods used here are marked as obsolete I was wondering what is now the correct way to accomplish the same. The warning message hints to: Please investigate the use of AppDomainSetup.ShadowCopyDirectories instead An AppDomain has a

Help needed with unloading .DLL's from AppDomain - Still not working even with ShadowCopy

有些话、适合烂在心里 提交于 2019-11-28 08:57:36
问题 I am trying to do the following. App A is the "mother app". It stays open. App B is just a .DLL where I write some classes that are derived from an interface specified in App A. Then, from App A, I will "import" classes from App B and run methods within them. I want to be able to dynamically change App B (change code and recompile) and use the new code in App A. I have a post-compile command in App B that copies the new .DLL to the App A directory. App A creates a new AppDomain and uses
