[.net 6] System.TimeZoneNotFoundException: The time zone ID 'Asia/Almaty' was not found on the local computer.

[Yerkon]

Hello,
After upgrading project from .net 5 to .net 6, error occurs on Windows Server 2019.

`

"Octonica.ClickHouseClient" Version="2.2.9"
For "Octonica.ClickHouseClient" Version="2.2.8" the same

But when running locally (Windows 10), it works

[Yerkon]

I fixed it by forcing local ICU through nuget App-local ICU. Probably, there is no ICU installed on Windows server 2019

I have the same problem on Windows 10 with " System.TimeZoneNotFoundException: The time zone ID 'Europe/Berlin' was not found on the local computer.".
@Yerkon How did you solve the problem? I added the following lines in my .csproj file, but I still get the error.

<ItemGroup>
    <RuntimeHostConfigurationOption Include="System.Globalization.AppLocalIcu" Value="72.1.0.3" />
    <PackageReference Include="Microsoft.ICU.ICU4C.Runtime" Version="72.1.0.3" />
</ItemGroup>

[Yerkon]

@MrDoe, only include in Windows platform:

<ItemGroup Condition="$([MSBuild]::IsOSPlatform('Windows'))">
   <PackageReference Include="Microsoft.ICU.ICU4C.Runtime" Version="68.2.0.9"/>
   <RuntimeHostConfigurationOption Include="System.Globalization.AppLocalIcu" Value="68.2"/>
</ItemGroup>

Also, in program you can check if IcuMode enabled with method:

 private static bool IcuMode()
 {
     SortVersion sortVersion = CultureInfo.InvariantCulture.CompareInfo.Version;
     byte[] bytes = sortVersion.SortId.ToByteArray();
     int version = (bytes[3] << 24) | (bytes[2] << 16) | (bytes[1] << 8) | bytes[0];

     return version != 0 && version == sortVersion.FullVersion;
 }

[MrDoe]

@Yerkon Thanks for your answer! I tried this, the IcuMode works, but I still get the error. Maybe it is an issue with .NET 8 running on Windows 10.

I debugged the library and changed

[MethodImpl(MethodImplOptions.AggressiveInlining)]
 static partial void GetTimeZoneInfoImpl(string timeZone, ref TimeZoneInfo? timeZoneInfo)
 {
     timeZoneInfo = TimeZoneInfo.FindSystemTimeZoneById(timeZone);
 }

to

[MethodImpl(MethodImplOptions.AggressiveInlining)]  
 static partial void GetTimeZoneInfoImpl(string timeZone, ref TimeZoneInfo? timeZoneInfo)  
 {  
     if (RuntimeInformation.IsOSPlatform(OSPlatform.Windows))  
     {  
         timeZone = TZConvert.IanaToWindows(timeZone);  
     }  
     timeZoneInfo = TimeZoneInfo.FindSystemTimeZoneById(timeZone);  
 }

in TimeZoneHelper.Net6.0.cs.

Now it works, but I get another error: ""TODO: add support for custom serialization."
But I guess this is another issue. Do you know by chance what "custom serialization" means?

The error is occuring when I try to select a DateTime64 column. As a workaround, I'm currently using toString(myDateTime64Column) in my queries.

@MrDoe, maybe @victor-sushko will help?

In recent versions ClickHouse "breaks" wire protocol.
You can disable sparse columns feature or wait for release with sparse column see #85 (couple of days)
