Quartz.net - Could not load file or assembly Common.Logging Version=3.0.0.0

Question

Im using Quartz.net in my project, and suddenly I get this exception :

Could not load file or assembly 'Common.Logging, Version=3.0.0.0...

I have no idea why it poped, everything was just fine, and the quartz worked, And suddenly it didn't. Why?

Answer 1

This typically happens when you ad a reference to a new assembly that also uses Common.Logging, but a different version. When the project build it picks up the incorrect version and then starts to complain as Quartz.net is bound to a particular version.

One fix for this is to do a bindindRedirect in the app.config.

Answer 2

因此，几个小时后，我用完全相同的代码打开了另一个项目，我发现由于某种原因，石英在重建项目后创建了Common.Logging dll，并且由于某种原因，它没有没有在我的原始项目中创建它，所以我只复制了dll。
