Referencing binaries from one project in another

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 b开发者_开发技巧uildserver where to find the binaries from B\bin\Release?

You do this by creating 'Artifacts' and artifact dependencies.

If project A is dependent on project B, then you create an Artifact on project B using an artifact path like so:

bin/Release/B.dll

Then on project A you setup a artifact dependency on B with path like:

B.dll

And set the destination path to be where ever project A is expecting to find B.dll e.g.

./Libs

You can do other cool stuff like automatically archiving all your artifacts into a zip by using the syntax:

bin/Release/*.dll => B.zip

and access them via:

B.zip!B.dll

All these paths are relative to build directories so makes it easy and you dont need to worry about the TeamCity guid folders or use absolute paths.

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.
