I am writing a server and an MMC console app that use remoting to talk
to each other. The MMC client and the server share a couple of
assemblies: one has the interface that is remoted from the server and
the other has some data structures that are passed across the remoted
interface from the server to the client. These assemblies are not
strong named and are not entered in the GAC. I could easily solve
this problem by putting the DLL in the System32 directory or in the
GAC, but I am trying to understand why it won't load one of the DLLs.
The directories are setup like this:
Machine A
\Program Files\Server\Se rver.exe
\Program Files\Server\Re mote.dll
\Program Files\Server\Da taStructs.dll
Machine B
\Program Files\Client\MM CSnapin.dll
\Program Files\Client\Re mote.dll
\Program Files\Client\Da taStructs.dll
The server runs on Machine A as expected. The MMC console runs on B
with the following problem: it loads the MMCSnapin.dll and Remote.dll
just fine but it can't load DataStructs.dll or atleast it thinks it
can't. I put a breakpoint in the MMCSnapin.dll where it creates the
remoted interface. At that point, I look at the Debug/Modules window
and I see all 3 DLL's loaded. I can even create objects from the
DataStructs.dll with no problem. The problem occurs when I call a
method on the remoted interface that returns one of the objects from
DataStructs.dll . The method throws an exception and says it can't
find the assembly, even though the Modules window says that it is
already loaded. I also checked
AppDomain.Curre ntDomain.GetAss emblies() and the DataStructs.dll
assembly is there as it should be.
If I put the DataStructs.dll in the System32 directory where MMC.exe
is, it loads the assembly just fine and calls the remoted method
correctly. I suspect it would behave correctly if I put the assembly
into the GAC as well. But right now, my question is: why does the
Modules window say the assembly is loaded but calling the remoted
method cause it to not be able to find the assembly? I have
repeatedly compiled all components and scoured my drive to make sure
the are no outdated assemblies floating around to confuse things.

Hi,
your MMC client is acting as part of the MMC proceess, and it's working
directory is System32. You can capture the AppDomain.Assem blyResolve
event, and there to load the assembly you need from where it is.

Hello group.
I have an app which can load "plugins" assemblies that are described
in the registry (each registry entry gives the full path to the plugin
..dll file). The plugins may be anywhere on the disk.
Each plugin defines a class which implements an interface known to the
app. The main app loads the plugin with Assembly.LoadFrom and then
uses Assembly.GetTypes() and Type.FindInterface to find the concrete
types in the plugin that...

Suppose an assembly "Main" is using class "A" from another Assembly "Dep" as

At what time is the call to MethodOne linked to the actual MSIL (method
body) of the method? Does this occur when "Main" is build or does it happen
when main is loaded and Jitted? Also is the linking achieved by the full
method name( this is what is seen in the IL generated by ILDASM : e.g : call

I wan't to be able to deserialize a class from an assembly that is not in
the application domain. To do that I must have the Type from the Assembly.
How do you get a Type from an assembly that is not in the manifest of the
current AppDomain. I have tried different ways but get exceptions from all
of them that say the:
assembly or one of its dependancies could not be found.
There must be missing something.

Morning all,
Right, I've read untold articles now, listening to people bitch about there
being no Unload method for Assembly.
Plenty of people do counter that this is possible by loading the Assemblies
into a seperate AppDomain and closing it when finish, which would suit me
fine.
However, I have been able to find an example.

I've looked through the previous posts on this one and have verified

The directory where my Dlls are located give the ASPNET user full

local folder with the rest of the web application Dlls.
Could someone take a look at my error and shed some light on this?

Hi,
I have been searching around to try adding reference assembly to
another assembly during runtime, programatically. Is this possible
in .Net?
The reason for this is because i am having trouble using a library
that creates an instance of a Type that i specified, and it failed the
locate the Type during runtime, if i do not reference it during
compile time.
