Specifying other variables for HttpPostFormOptions during run time

SAML for ASP.NET Core
1

In version 2.9.0 of SAML for ASP .NET Core that I’m currently using and trying to upgrade from, I was able to override OtherFormVariables dictionary and provide my own form variables during HTTP post. In v4.3.0, OtherFormVariables is no longer public and I can’t override. The only way to specify my own variables is during HttpPostForm configuration, but that doesn’t help in my business scenario, since I need to set the variable later in the process. The only way I was able to do it is to use reflection and get private httpPostFormOptions variable and set httpPostFormOptions.OtherFormVariables when I override public override HttpPostFormContent Create(string url, string messageFormVariableName, string messageFormVariableValue,
string relayStateFormVariableName, string relayStateFormVariableValue) method.

This is really something I would like to avoid, but I can’t find any other solutions.

Other form variables may be set as follows:

using ComponentSpace.Saml2.Bindings.Post;

builder.Services.Configure<HttpPostFormOptions>(options =>
{
    options.OtherFormVariables = new Dictionary<string, string>
    {
        { "name1", "value1" },
        { "name2", "value2" }
    };
});

Are you after something more dynamic?

Yes, I need it to be dynamic. Basically, I need it to be set after I get some information from the database during initiate SSO login process.
