Description of problem

Currently the only constructor for SupportedModulesAttribute takes a single string parameter that it attempts to split on commas in order to build the supportedModules string array like this:

public SupportedModulesAttribute(string supportedModules)
{
    this.supportedModules = supportedModules.Split(new[] { ',' });
}

This has the downside of being error prone. For example, our team made the mistake of adding a space after a comma (',') character which caused API requests to the second module to not be accepted.

It also has other downsides like being hard to read especially once you have a handful of supported modules
[SupportedModules("Test: Module1,Test: Module2,Test: Module3,Example: Module4")]

Description of solution

I suggest adding an additional constructor to SupportedModulesAttribute that takes a params string array as its only parameter that can be directly assigned to the supportedModulesArray like so:

public SupportedModulesAttribute(params string[] supportedModules)
{
    this.supportedModules = supportedModules;
}

Description of alternatives considered

An alternative would be to allow multiple [SupportedModules] attributes on a single class as currently it seems only the first of the attributes will function as intended.

If approved I will happily submit a PR and have the code ready to do so now.
