“Could not load file or assembly”/ “or one of its

Question

I have a c# application which uses SharpSVN dll and NServicebus dll,it compile fine but when it is executing(in the time of initialize the bus) it throw the following error

Could not load file or assembly 'file:///C:\Repositories\Repo\hooks\SharpSvn-DB44-20-Win32.dll' or one of its dependencies. The module was expected to contain an assembly manifest.

How can I solve the above problem.

Thank in advance Susanta

Answer 1

Susanta,

We recently committed an additional API which can be things easier for you by allowing you to specify which assemblies not to load as follows:

Configure.With(AllAssemblies.Except("SharpSvn-DB44-20-Win32.dll"))... // rest of your config

Answer 2

The problem get resolved by using the following bus configuration.

Bus = NServiceBus.Configure.With(typeof(IMessage).Assembly, typeof(CompletionMessage).Assembly) .SpringBuilder().MsmqSubscriptionStorage().XmlSerializer().MsmqTransport() .IsTransactional(true).PurgeOnStartup(false).UnicastBus().ImpersonateSender(false) .LoadMessageHandlers().CreateBus().Start();

Thanks to Andreas

The SharpSvn-DB44-20-Win32.dll is an optional helper dll for SharpSvn.dll. It contains only unmanaged code.

It contains support for directly accessing BDB repositories on the filesystem. You don't need this DLL if you only use fsfs (file://) and/or remote repositories.

The SASL dll is also optional, but you need that when you want to use svn:// repositories.

I'm not sure if this will help you or not, but I have stumbled on this thread:

It appears that a few people have seen this error when building / running assemblies with the same name, so for example:

SomeAssembly.exe
SomeAssembly.dll

Could this be applicable in your case?

Answer 5

Exclude the sharpsvn dlls from the NServiceBus assemblyscanning by configuring NSB with a explicit list of assemblies toi scan:

Configure.With("List of your assemblies that contain messagehandlers")...

Make sure to include NServiceBus.core.dll in the list if you're using the Saga feature.

Hope this helps!
