Newbie question : I have 2 C# projects in TeamCity, call them A and B. A contains a reference to B.dll. B builds fine. However, A fails to build because it cannot find B : Could not locate the assembly "B"
It seems really simple : how do I tell my project A on the buildserver where to find the binaries from B\bin\Release?
The problem you're encountering is that Teamcity runs each build in it's own temporary directory and since this is a randomly generated name you can't set a reference directly from one to the other.
Typically you would write a build script that builds both A and B in the right order and just have Teamcity run that build script. (Since you're using C#, MSBuild is ideal for this).
The alternative would be to have B.dll copied to a known location (e.g. c:\currentbuild) at the end of its build and have A always reference it from here. You can set up build dependencies in Teamcity so that if B is rebuilt, A is also rebuilt.
