I'm facing and interesting and blocking problem with the publisher policy
file use.
I have three strong named assemblies:
MyCompany.Product1.dll, Version=5.0.0.1, Culture=neutral,
PublicKeyToken=f6815420c0e3f3fc
MyCompany.Product2.dll, Version=5.0.0.1, Culture=neutral,
PublicKeyToken=f6815420c0e3f3fc
MyCompany.Product3.dll, Version=5.0.0.1, Culture=neutral,
PublicKeyToken=f6815420c0e3f3fc
- Product2 only references .NET framework stuff (System.dll, etc)
- Product3 references .Net framework and also Product1
I have all three in the GAC of my server and I'm trying to install version
5.0.0.2 of Product2 and Product3
For Product2, I did as described in the SDK documentation, created the
policy file and the policy assembly:
(policy2.xml)
<configuration>
<runtime>
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<dependentAssembly>
<assemblyIdentity name="MyCompany.Product2"
publicKeyToken="f6815420c0e3f3fc" />
<!-- Redirecting to version 5.0.0.2 of the assembly.. -->
<bindingRedirect oldVersion="5.0.0.1"
newVersion="5.0.0.2"/>
</dependentAssembly>
</assemblyBinding>
</runtime>
</configuration>
al /embed:policy2.xml /out:policy.5.0.MyCompany.Product2.dll
/keyfile:My_keyfile.snk
I installed the policy assembly and the new assembly in the server's GAC and
it worked like a charm, very nice!
BUT ... when I tried the same thing for Product3 (which references another
assembly with the same publicToken name) using a similar policy file and
assembly:
(policy3.xml)
<configuration>
<runtime>
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<dependentAssembly>
<assemblyIdentity name="MyCompany.Product3"
publicKeyToken="f6815420c0e3f3fc" />
<!-- Redirecting to version 5.0.0.2 of the assembly.. -->
<bindingRedirect oldVersion="5.0.0.1"
newVersion="5.0.0.2"/>
</dependentAssembly>
</assemblyBinding>
</runtime>
</configuration>
al /embed:policy2.xml /out:policy.5.0.MyCompany.Product3.dll
/keyfile:My_keyfile.snk
When I ran anu code that tries to load MyCompany.Product3.dll ()version
5.0.0.1 or even 5.0.0.2) I get the following error (PolicyGen.exe is my test
app):
System.IO.FileLoadException: Unable to load file 'MyCompany.Product3'.
The line of code looks like:
string typ = typeof(MyCompany.Product3.SomeClass).FullName;
The fusion log viewer (fuslogvw.exe) gives me the following report:
*** Assembly Binder Log Entry (10/11/2002 @ 5:21:29 PM) ***
The operation failed.
Bind result: hr = 0x80070103. No more data is available.

The dll's are still in the same folder as when they were copied to the GAC.
Any clues ??? Am I doing anything wrong? Is this a known issue?
Thanks in advance for any help here!!
