Hello All.

Can anybody describe me why this code:

string assemblyPath = "myassembly.dll";
X509Certificate cert = X509Certificate.CreateFromSignedFile(assemblyPath);

Evidence evidence = new Evidence();

evidence.AddHost(new Publisher(cert));

AssemblyName asmName = AssemblyName.GetAssemblyName ( assemblyPath );

Assembly asm1 = Assembly.Load(asmName);

Assembly asm2 = Assembly.Load(asmName, evidence);

Assembly asm3 = Assembly.LoadFrom(assemblyPath);

PublisherMembershipCondition cond = new PublisherMembershipCondition(cert);

Console.WriteLine("Evidence check: {0}", cond.Check(evidence));

Console.WriteLine("1 assembly check: {0}", cond.Check(asm1.Evidence));

Console.WriteLine("2 assembly check: {0}", cond.Check(asm2.Evidence));

Console.WriteLine("3 assembly check: {0}", cond.Check(asm3.Evidence));

//------------------------------------

output:
Evidence check: true

1 assembly check: false

2 assembly check: false

3 assembly check: false

I signed assembly by call:

signtool.exe sign /f key.pfx /p mypassword /v myassembly.dll

When I create AppDomain, I set domain policy:
PolicyLevel policyLevel = PolicyLevel.CreateAppDomainLevel();

string assemblyPath = "myassembly.dll";

X509Certificate cert = X509Certificate.CreateFromSignedFile(assemblyPath);

CodeGroup codeGroup = new UnionCodeGroup(new
PublisherMembershipCondition(cert), new PolicyStatement(new
PermissionSet(PermissionState.Unrestricted)));

policyLevel.RootCodeGroup = codeGroup;

domain.SetAppDomainPolicy(policyLevel);

Thanks a lot for any help.
