Any idea on the release date for this?

Hello,
I saw the v2.1.0-preview1-26216-03 is already available, but I it seems this fix is not there and is marked for Servicing-Approved-2.0.6. Does this mean we should expect .NET Core 2.0.6 and this particular fix in this package? If so when do you think .NET Core 2.0.6 should be released? Thanks in advance

2.0.6 is expected this month.

@MStefanov The fix is available in SqlClient preview version 4.5.0-preview1-26216-02
What problems are you facing ? Can you open an issue and let us know what issues you are seeing?

[saurabh500]

Also the same fix is going in 2.0.6
If something is not working in 4.5.0-preview with respect to connections, it may not work in 2.0.6 either.

What version of the System.Data.SqlClient NuGet package do we need for this fix? We are targeting .NET Core 2.2 and using 4.6 of the NuGet package but running in to very similar issues in our docker containers. Trying to determine how we can tell if our connections are using this fix.
