WPF Best pratice for MassTransit Init

[Terry Massey]

All,

So I am working on a large enterprise wide Project and I am prototyping out for test of MassTransit with RabbitMQ and WPF. I have recreated essentially a slimmed down test case of your StarBucks app but for the customer I am using WPF. The problem is I am not sure the best place to Initialize MassTransit in the WPF Client. So that is question 1.

 

Question two is I think the nugget packages are broken. Well at least the ones I installed into my project. I get a topshelf exception because the log4net version that auto installed as a dependency is version 4 and it is looking for version 1.2.10.0

 

thanks,

Terry

you want to initialize the bus at the start of the application, typically when you spin up the container. are you using IoC?

i believe there is a fix coming that will lock down the log4net issue. so hopefully that will squash that.

Dru,

Yes I am using Windsor, 

that is awesome. 

Thanks,
Terry Massey

[Dru Sellers]

so with windsor I like to have an 'installer' that contains all of the MT setup, and then just add it to the initialization process of the IoC.

Regarding log4net: You can set allowedVersions in your package.config to force log4net 1.2.10.

If you are still having bother with the log4net public key change
issue (the version obtained from nuget has the new public key) then
you may wish to look at this post on stackoverflow for a work around
