  Appdomain.CreateInstance is not working when the project is migrating to 3.5 from 2.0

  Jul 16, 2008 08:04 AM|LINK

  Hi,

  I have a project which was develpoed in .Net 2.0, C#.

  In that project a Appdomain is created dynamically and creating a instance of the Dll within that Appdomain.

  It's working fine with .net 2.0

  my code piece is looking like the below

  try

  {

  // initialize tempDir to something like <LocalUser\Application Data> ...

  tempDir = CreateTempDir(adHocDomainName);

  PutConfigAndPolicy(tempDir, adHocDomainName, wsePolicy);

  // create ad hoc domain

  adHocDomain = createDomain(adHocDomainName, tempDir);

  System.Reflection.Assembly myAssembly = System.Reflection.Assembly.GetAssembly(typeof(Adapter));

  PolicyLevel pl = PolicyLevel.CreateAppDomainLevel();

  // include a code group that gives permissions only to assemblies

  // that are strong named with s_somePublicKey

  StrongNameMembershipCondition snMC = CreateStrongNameMembershipCondition(myAssembly);UnionCodeGroup snCG = new UnionCodeGroup(snMC, new PolicyStatement(new PermissionSet(PermissionState.Unrestricted)));

  pl.RootCodeGroup.AddChild(snCG);

  // set our new policy as the domain-level policy

  adHocDomain.SetAppDomainPolicy(pl);

  // identify our assembly

  string myFullName = myAssembly.FullName;

  string stubFullTypeName = typeof(crossDomainStub).ToString();

  crossDomainStub crossDS = null;

  // load an instance of crossDomainStup into ad hoc AppDomain

  System.Security.Policy.Evidence adEvidence = myAssembly.Evidence;

  try

  {

  System.Runtime.Remoting.ObjectHandle oh = adHocDomain.CreateInstance(myFullName,stubFullTypeName,false,System.Reflection.BindingFlags.CreateInstance,null,null,null,null,adEvidence);crossDS = (crossDomainStub) oh.Unwrap();

  }

  catch(Exception ex)

  {

  }

  Recently I migrate the project to Visual studio 2008.

  It's working fine if I am running it under .Net 2.0

  But failing in .net 3.5.

  The Exception is "Request for the permission of type 'System.Security.Permissions.SecurityPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed."

   

  and the stack trace is

     at System.Security.CodeAccessSecurityEngine.ThrowSecurityException(Assembly asm, PermissionSet granted, PermissionSet refused, RuntimeMethodHandle rmh, SecurityAction action, Object demand, IPermission permThatFailed)
     at System.Security.CodeAccessSecurityEngine.ThrowSecurityException(Object assemblyOrString, PermissionSet granted, PermissionSet refused, RuntimeMethodHandle rmh, SecurityAction action, Object demand, IPermission permThatFailed)

     at System.Runtime.Serialization.ObjectCloneHelper.GetObjectData(Object serObj, String& typeName, String& assemName, String[]& fieldNames, Object[]& fieldValues)

  
     at System.AppDomain.CreateInstance(String assemblyName, String typeName, Boolean ignoreCase, BindingFlags bindingAttr, Binder binder, Object[] args, CultureInfo culture, Object[] activationAttributes, Evidence securityAttributes)
     at Microsoft.MySalesComp.Adapter.SoapCallWSE(String targetURL, String soapAction, XmlDocument soapBody, XmlDocument wsePolicy, String certificateCaptionAndCacheKey, String userTokenCaptionAndCacheKey) in D:\POC\ExcelAddIn_MIC_2008\DashboardUI\WSE\Adaptor.cs:line 341

   If I am trying to run it again in 2.0 than also it's not working.

  If you have any information to reso;ve this problem please share with me.

  Thanks & regards,

  Rajib
