Hi @VictorDevmetro, What is your .NET version?

commented

Ok .. If possible, Can you provide a sample project to reproduce the issue?

Hi @VictorDevmetro, I couldn't reproduce this issue when I use it in applications(you can try out the sample applications here & let me know ). But however when I run the test cases in Visual Studio, I encounter this issue. But the same test cases ran in .NET CLI using dotnet test command doesn't throw this error. Pretty interesting bug. I'll look into it. In the meanwhile keep using v1.5.0.
Thanks!

Update: I updated the test project form MSTest to xUnit .. now there's no such error in both Visual Studio & .NET CLI

If you can provide me a sample project, I'll be able to look at it.

Thanks :)

Hi @VictorDevmetro , When we remove RazorTemplateEngine.Initialize(); from your Program.cs, the error is gone. The library creates the cache itself when it's run for the first time. So you can safely remove it.

I'll investigate why it's throwing error in your use case in v1.6.0

commented

Update: Problem is specific to worker service when RazorTemplateEngine.Initialize(); is called in bootstrap code in v1.6.0. It's advised to remove this line until a fix is released.
Please note, removing this line doesn't make any big difference. The core feature will work as before.

Thanks!
