Dynamics 365 Function Parameters (need to remove quote)

[Slackter]

Hello,

We are utilizing the latest version of this library very heavily without any issues at all so it's been great. We are in need of executing a function and need to specify a function parameter in a very specific format.

The function requires a parameter of Target=@tgt (@tgt can be anything) but there must be NO quotes at all.

If I run use the following code:
client.For<SystemUser>.Key(userGuid).Function("RetrievePrincipalAccess").Set(new { Target = "@tgt })

the library will generate a URL as follows:
https://server/api/data/systemusers(userGuid)/Microsoft.Dynamics.CRM.RetrievePrincipalAccess(Target='@tgt')

when it needs to be:
https://server/api/data/systemusers(userGuid)/Microsoft.Dynamics.CRM.RetrievePrincipalAccess(Target=@tgt)

Is there any way to remove the single quotes the Set() is adding to my URL?

I was able to get this working by using the BuildRequestFor() and modifying the RequestUri directly, but I am unable to write proper unit tests since the ODataRequest has only internal constructors and is un-mockable.
