Implement EndpointSelector and MatcherPolicy This change makes the EndpointSelector API more concrete, and is the beggining of removing EndpointConstraint by making it obsolete. To that end, I'm introducing MatcherPolicy, which is a feature-collection API for registering policies that interact with the DfaMatcher. The two policies that we'll need to start are: - ability to order endpoints - ability to append 'policy' nodes to the graph These two concepts together replace EndpointConstraint. Extending our graph representation is a really efficient way to processing most common scenarios. --- In general this helps with common cases where 4 or so endpoints match the URL, but with different HTTP methods supported on each. Today we have to process route values and call into some 'policy' to make a decision about which one is the winner. This change pushes this knowledge down into the graph so that it's roughly as cheap as a dictionary lookup, and can be done allocation-free. The big savings here is ability to remove more candidates *before* collecting route data. --- Along with this change, I also built 'rejection' into the DFA node model, you can see an example with the HTTP Method handling that I implemented. I implemented a policy that can treat failure to resolve an HTTP method as a 405 response by returning a failure endpoint. This is at the heart of much of the feedback we've gotten in this area around versioning and http method handling. We also have a version of this feature in MVC for [Consumes]. |

Compile the solution in Release mode (so binaries are available in release)
To run a specific benchmark add it as parameter.
dotnet run -c Release --framework <tfm> <benchmark_name>
To run all benchmarks use '*' as the name.
dotnet run -c Release --framework <tfm> *
If you run without any parameters, you'll be offered the list of all benchmarks and get to choose.
dotnet run -c Release --framework <tfm>
