Thanks. I made this same change in #377.
@eiriktsarpalis I know we run our tests on net9.0 and net8.0, do you think we should include net472? If we did that, we would need to write multi-process tests so ASP.NET Core can still run to get good coverage for the HTTP-based client code.

Fixed exception 'The format of value 'application/json; charset=utf-8' is invalid
Motivation and Context
Without this fix it doesn't work at all with .NET Framework.
"application/json; charset=utf-8" is an invalid header when the encoding is already specified. It fails immediately when creating the McpClient instance with the SseClientTransport using netstandard builds.
How Has This Been Tested?
Works. Without the fix doesn't work at all.
Breaking Changes
Not a breaking change.
