For link generation to areas, we need to provide the set of values that
the route could potentially provide.
Basically if we know what action we want to reach, we want to know whether
or not a given route could hit that action before giving it the OK to
generate a link.
For instance a route like '{controller}' couldn't hit an action like
'HomeController:DoACoolThing', since it can never provide a value for
'action'. This makes it possible for WebFX to make the right decision
without changing the behavior of any of the routing constructs. This also
has the side-effect of removing a class of order dependencies in routing
that cause bad links to be generated.
The code that does an 'UPSERT' of seed data on app start was querying
existing instances and attaching as modified of seed instances on the
same context. Now that we track query results this will throw because
the context has two instances of the same entity (same key value).
Swapping to use a temporary context to query existing data.
1. Adding scripts to self host & custom host Music store
2. Updating readme
3. Cleanup some helper classes that are not necessary.
4. Adding error page middleware for diagnostics.
5. Flipping the switch to run helios on "K" by default.
We'll need to access the accepted values to do proper link generation, so
separating this process out into 2 parts.
Also moving defaults into the TemplateBinder because they are conceptually
part of the route, not part of the request. I'll do the same for
TemplateMatcher soon, but it's a big change and worth separating.
Swapping context to use OnModelCreating & OnConfiguring now that models
are cached
Adding some [Required] annotations to properties that are really
required in the domain model
Renaming Cart => CartItem because that's what it really is :)
Allowing database to hold some null data now that we can materialize it
(although we can't save it yet)
