CSharp/C#, Strong name assemblies patching problem

1. Strong Named Assemblies and Non Strong Named assemblies

Hi All

I have a third party .net assembly that I do not have the code for and it 
also does not have a strong name.

I want to strongly name my assemblies but I keep getting an error saying 
that the 3rd party assembly is not signed.

I have had a look at the tlbimp.exe but this looks like it only works for 
ActiveX/COM componants, NOT .Net assemblies.(Unless I am typing in the wrong 
commands....keep getting error not a valid type library)

Is there some compile switch or something that will not check on this 3rd 
party dll for a strong name?

Thanks

David

3. Strong Naming a Non-Strong Named assembly

Hi,

Yes, you can sign it later using sn.exe provided you have the private key of
the public-private key pair.

Delay Signing is something related with module based development where
individual, small teams doesn't have access to the private key for that
organisation. So they sign the AssemblyKeyFile with the public key & set the
AssemblyDelaySign = true to enable to have room for the private key to be
hashed later. Later, the resulting assembly is re-signed using the private
key using the -R switch of sn.exe.

5. Restricting access to Assembly.LoadFrom call within an assembly based on strong names

Surya,

    You aren't going to be able to do this.  You are going to have to
implement a load mechanism yourself and then have all of your code go
through that mechanism.

    Hope this helps.

7. hexedit assembly - snk, strong name, sing assembly question

Hello

How can I ensure that a assembly (dll) is not manipulated (e.g.
hexeditor).

I thought that  sign the assembly (snk-File), this ensures.

I have tried the following.

1.
Create assembly Test.Dll with  AssemblyVersionAttribute("1.1.*") and
sign with Test.snk  (Property-Page and/or
AssemblyKeyFileAttribute(@"Test.snk")

2.
Create UseTest.Exe with reference to Test.Dll.

--> Now UseTest.Exe requires the desired Test.Dll,  ok

However, I can manipulate Test.dll (Hexeditor) an use it !!   e.g.
Class Test1 in Test.Dll

  public class Test1
    {
        public static void SayHallo()
        {
            System.Windows.Forms.MessageBox.Show("Hallo Peter");
        }
    }

Change text Hallo Peter with hexeditor to Hallo Qeter


Do I something wrong ?
or is signing not at all thought my problem ?

Is there built in mechanism to "checksum" a assembly

thank you
Peter
