jQuery operates client-side, so you can't talk to it directly. You have two options, then:

• request the value via http (perhaps using SignalR as a messaging layer, since you are referencing that)
• serialize the dictionary as JSON into the request

Fortunately, the latter is fairly trivial for most common types - here using Json.NET:

var data = new Dictionary<string, object>
{
    {"foo", 123},
    {"bar", "abc"},
    {"blap", true}
};
var json = JsonConvert.SerializeObject(data);

which gives us the JSON:

{"foo":123,"bar":"abc","blap":true}

If you assign that into a variable in the <script>, then values can be referenced either as obj.bar or as obj['bar']. However: keep in mind that all values will be serialized if you do this - you may want to be more restrictive in terms of tracking which the client actually cares about (or should be allowed to know about).

Important point, though: if your "static dictionary" is actually a static dictionary, then please consider very carefully the impact of multiple users. static is a really good way to write a web-site that only scales to a single user.
