{"The given assembly name or codebase, 'MyAssemblyDisplayName', wa

Hi,
I'm creating an AppDomain and creating an instance of a class. This works
fine unless I use caching, which I need to use.
The exception that I get is of type "System.IO.FileLoadException" which
message is:

{"The given assembly name or codebase, 'MyAssemblyDisplayName', was
invalid." }

The stack trace is:

What are the values of the assemblyDisplayName and myClassDisplayName
arguments you are passing to CreateInstanceAndUnwrap?

Dear David,
Thanks for your interest. They are like this:
assemblyname: MyCompany.Solutions.MyProduct.MyAssemblyName
typename: MyCompany.Solutions.MyProduct.MyAssemblyName.MyTyp eName

As you can see I'm passing just the name with its full namespace to the
CreateInstanceAndUnwrap method. Besides, it works well if I do not use
caching, so I think this values are right.

What do u think it is happening ? thanks again.

Is the actual name of the assembly
MyCompany.Solutions.MyProduct.MyAssemblyName.DLL? Or are you including the
namespace as part of the assembly name? If so, don't do that. Also, make
sure that the assembly is in a directory that is located by the normal
probing that the fusion layer uses. You should also look at fuslogvw.exe and
see if it is able to locate the assembly and if not, why not.

Ok, thanks again for answering.
The actual name of the assembly is
MyCompany.Solutions.MyProduct.MyAssemblyName.DLL.

I will probe the utility you mention. I hope I will do it tomorrow.

Thanks again.
Pablo

Dear David,
I am trying fusloggvw but no information is reported. Additionally, I have
set the registry key 'ForceLog', but nohting is displayed.

Do you have another idea ??

Thanks again.
Pablo.

Try specifying the complete assembly name, which is "AssemblyName,
Version=xxx, Culture=xxx, PublicKeyToken=xxx"
