How to link multiple visual studio solutions together?

Question

I have 3 solutions and solution A requires built versions of the dlls from solution B and C in order to compile. it is not possible to merge it to one solution...

So far

Answer 1

It should be project level you are looking at I believe. Build the projects contained within Solution B and C and then add references to the DLLs in the relevant projects in Solution A.

In Msbuild if you have a property group

SolutionB
SolutionC
SolutionA

Then execute the MSBuild Task

Hope this helps
