c# - In the same project two libraries need two different version of a third library -

in c# project need make backplane signalr realized azure service bus. in startup wrote:

globalhost.dependencyresolver.useservicebus(asb_endpoint, topic); 

in same project there's rebus configuration azure service bus, like:

return rebus.config.configure.with(new unitycontaineradapter(container))             .logging(l => l.log4net())             .transport(l => l.useazureservicebus(cs, qname))             .routing(r => r.typebasedroutingfromappconfig())             .options(o => o.simpleretrystrategy(errorqueueaddress: errorqname, maxdeliveryattempts: 3)); 

both uses extension method implementation of useazureservicebus , useservicebus.

the problem is: both extension methods part of 2 libraries, , libraries conflicting on various dependencies. have rebus' useazureservicebus extension, need rebus.azureservicebus version 0.99.39, in turn needs @ least windowsazure.servicebus 3.0.4, use dll called microsoft.servicebus 3.0.0 conflicts internal work of extension method useservicebus.

how can handle this?

edit 1 : looks problem fixed microsoft.aspnet.signalr.servicebus version 2.2.2. don't know in meanwhile

it sounds need give each assembly alias, can use class in version.

see:

what use aliases property of assembly references in visual studio 8

here walkthrough: https://blogs.msdn.microsoft.com/ansonh/2006/09/27/extern-alias-walkthrough/

  extern alias fooversion1;     fooversion1::acme.foo f = new fooversion1::acme.foo();   f.bar(); 

the other option have use global alias on default, can use global full namespace of class need use if exists in 2 different assemblies.

eg:

global::assembly1.class1 c = new global::assembly1.class1(); global::assembly2.class1 c2 = new global::assembly2.class1();
