Missing "Microsoft.CodeAnalysis" in .net 3.1 install on Ubuntu

I have a .net project that runs in windows with VS code with no issues.
I am trying to run the same project in Ubuntu 20.04.2 with VS code. Run trying to run it with F5, I get the errors:
CSC : error CS8032: An instance of analyzer System.Text.Json.SourceGeneration.JsonSourceGenerator cannot be created from /home/one/.nuget/packages/system.text.json/6.0.6/analyzers/dotnet/roslyn3.11/cs/System.Text.Json.SourceGeneration.dll : Could not load file or assembly 'Microsoft.CodeAnalysis, Version=3.11.0.0, Culture=neutral, PublicKeyToken=****'.

It looks like "Microsoft.CodeAnalysis" was missing. So, I installed it with nuget in VS code. I added 'nuget: add package' in VS code to install 'Microsoft.CodeAnalaysis' version 3.11.0.
I have verified it successfully lives on my system:

I still get the errors mentioned above.

DST Entry time for few Timezone (Europe/Nicosia) are reporting wrong date using System.Globalization C#

I'm trying to get the DST entry time for the timezone "Antarctica/McMurdo" for the current year 2020 using System.Globalization class in C#. i'm receiving them as
DST Entry Time: 9/29/2020 2:00:00 AM
DST Exit Time: 4/5/2020 2:59:59 AM
But the actual DST entry time supposed to be on 9/27/2020 2:00:00 AM according to https://www.timeanddate.com/time/change/antarctica/mcmurdo
The received entry time is already in DST because of which my test program is failing as the time shift is not happening.
Below is the code snippet used
var currTimeZone = TimeZone.CurrentTimeZone;
var dstInfo = currTimeZone.GetDaylightChanges(now.Year);
DSTEntry = dstInfo.Start.ToString();
Below are the versions of Mono and Ubuntu i'm running on
Ubuntu 16.04.3 LTS
Mono JIT compiler version 5.4.0.201

Can someone help me how to resolve this timing issue? or is this a bug from DLL/timezone_database which C# is reading from?
Thanks

From the documentation on the TimeZone class:
Warning
This API is now obsolete
...
ⓘ Important
Whenever possible, use the TimeZoneInfo class instead of the TimeZone
class.
...
The TimeZone class supports only a single daylight saving time
adjustment rule for the local time zone. As a result, the TimeZone
class can accurately report daylight saving time information or
convert between UTC and local time only for the period in which the
latest adjustment rule is in effect. In contrast, the TimeZoneInfo
class supports multiple adjustment rules, which makes it possible to
work with historic time zone data.
In short, don't use the TimeZone class.

I suggest updating all SQLite-related packages on NuGet as well as the SQLite extension for Visual Studio (via Tools -> Extensions and Updates...)
Update
As I have learned, you use EntityFrameworkCore, which works only with Windows 10 Fall Creators Update and newer and will not work on older versions of UWP. To get rid of the issues, you will have to set your app to have minimum SDK version 16299 (FCU). If you need to support older versions, you will have to work without Entity Framework for now...

OpenVpn from C# - Weird Timeout

i am trying to start OpenVpn from my C# Windows Service. Basically like this:
VpnProcess = new Process();
VpnProcess.StartInfo.FileName = "<Path to openvpn.exe in Program dir>";
VpnProcess.StartInfo.Arguments = "--config " + "<vpnConfigName>" + " --log vpn.log";
VpnProcess.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
VpnProcess.StartInfo.UseShellExecute = false;
VpnProcess.StartInfo.CreateNoWindow = true;
VpnProcess.StartInfo.WorkingDirectory = <Program dir>;
VpnProcess.Start();
so far so good, here is the resulting log:

So, vpn hangs after VERIFY, then restarts itself, then its working fine. If i start openvn via cmd or Powershell with the exact same conditions and params, it connects successfully in the first try.
I spent several days trying to find out why this happens, no success. I tried all sensible combinations of StartInfo-Properties and checked whether the executing user changes after the soft restart. Nope, both times it's LocalSystem.

Cause: server time was 1 minute ahead of time. So the freshly downloaded certificate on client was 'from the future', leading to rejection by the server. Server log showed this, but never client log

Check your OpenVPN config file do you have option 'auth-nocache'.
I got a similar effect when I've added this option to client configuration. I use username / password to authenticate.

Test Webservice Method in Visual Studio: why does it say runs successfully without running the test and test fails?

I have created the default webservice asmx hello world :
namespace WebServiceHello
{
/// <summary>
/// Summary description for Service1
/// </summary>
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[System.ComponentModel.ToolboxItem(false)]
public class Service1 : System.Web.Services.WebService
{
[WebMethod]
public string HelloWorld()
{
return "Hello World";
}
}
}
I then generate a MS Test with Visual Studio and set expected value:
[TestMethod()]
[HostType("ASP.NET")]
[AspNetDevelopmentServerHost("C:\\temp\\WebServiceHello\\WebServiceHello", "/")]
[UrlToTest("http://localhost:7352/")]
public void HelloWorldTest()
{
Service1 target = new Service1(); // TODO: Initialize to an appropriate value
string expected = "Hello World"; // TODO: Initialize to an appropriate value
string actual;
actual = target.HelloWorld();
Assert.AreEqual(expected, actual);
// Assert.Inconclusive("Verify the correctness of this test method.");
}
but I got this error message:
The Web request
'http://localhost:7352/' completed
successfully without running the test.
This can occur when configuring the
Web application for testing fails (an
ASP.NET server error occurs when
processing the request), or when no
ASP.NET page is executed (the URL may
point to an HTML page, a Web service,
or a directory listing). Running tests
in ASP.NET requires the URL to resolve
to an ASP.NET page and for the page to
execute properly up to the Load event.
The response from the request is
stored in the file
'WebRequestResponse_HelloWorldTest.html'
with the test results; typically this
file can be opened with a Web browser
to view its contents.
and as Test Files :
WebRequestResponse_HelloWorldTest.html

The test shouldn't fail since actual is expected so what I did setup wrongly ?
