MSBuild - can it work out project dependencies in a solution file? If so how?

Question

I have an msbuild project which builds a SLN file from visual studio which holds all the projects in (about 70+ project), and a lot of the projects are dependent on each other m

Answer 1

If all of your dependent projects are in the solution and you are using Project references, Visual Studio should manage the dependencies for your and build in order of that dependency list.

It sounds like you are not using project references. I always recommend project references.
