Thanks for submitting the PR.
Actually there several things to consider while heading to a new v5.
Please understand the comments under this aspect.

The Organizer class might require more similar refactoring as proposed in the PR.
Examples:

• The class should up updated to use NRT.
• Should the setter for SentBy remove an existing Parameters entry?
• The getter for DirectoryEntry causes a similar issue. it should return null if no DIR entry exists.
• Decision about errors when creating the Uri - throw or use null instead? This may also concern the ParameterCollectionProxy.Set method.
• Unit tests missing

@minichma What do you think. Should we fix this issue in an isolated or a "fix it all" context?

[minichma]

I agree. This PR certainly is beneficial, but the same improvement as for SentBy should also be applied to DirectoryEntry at least.

@idiotsky Would you be ready to adjust the PR accordingly?

Generally speaking, I think that representing these values as Uri is not the best thing to do, so at some point we might consider replacing all the Uri values by simple string ones.

I agree with replace the Uri to string is better idea.
