I'm not being able to run Stryker in a project (netframework 4.5) inside a machine that doesn't have VS2017 installed (it has VS2015). Stryker fails when it tries to build the solution.

I ran some tests and found out that it tries to use the MSBuild.exe located at the first path defined on MSBuildHelper's.fallbackLocations.

Since dotnetcore's behavior when testing entire solution is trying also test non testing projects and then whole process is evaluated as non successful at least on linux, then I need to run test on one by one testing project separately I need to somehow then merge altcover results into one xml file, is that possible?

I want to use ETCD's ttl, and I noticed that there are some lease methods (LeaseGrant and so on) exposed from client, but I can't figure out how to use them.

Describe the solution you'd like
Add some usage examples in README.md.

Thank you for your creating the great client again.
