Accessing the SerialPort class using .Net Core 3.0

问题 I'm starting a new .NET Core 3.0 project in which I need to access the System.IO.Ports.SerialPort class. The documentation I'm reading on the class shows that it is applicable to .NET Core 3 ( see the bottom of https://docs.microsoft.com/en-us/dotnet/api/system.io.ports.serialport?view=netcore-3.0 ). However when I add a using statement to my class it isn't able to resolve System.IO.Ports. Is there some additional step that needs to be done to reference the SerialPort class for a .NET Core 3

.Net core 3: The namespace internal does not exist in Microsoft.Extensions.Logging.Internal

问题 I have a .Net core 2.1 project that was using the Microsoft.Extensions.Logging.Internal namespace, specifically FormattedLogValues class. I am now migrating to .Net core 3, I couldn't find a piece of documentation about where to FormattedLogValues was moved or what is its replacement. Even the namespace documentation is removed Any tips? 回答1: I fixed the problem by updating moq to "4.13.1" and taking advantage of It.IsAnyType . _logger.Verify(f => f.Log( It.IsAny<LogLevel>(), It.IsAny<EventId

Outlook Interop in .NET Core 3.0?

孤人 提交于 2020-11-27 05:29:11
问题 I migrated our project from .NET Framework to .NET Core 3.0 (C#, WPF) and now I can not use Microsoft.Office.Interop.Outlook anymore, because it is not compatible with .NET Core 3.0. What I want to archive is opening/sending prefilled Outlook-Mails. Is there an alternative to this interop dll , or maybe a way to use .NET Framework for only this reference? Thanks and best regards! Microsoft.Office.Interop.Outlook, NetOffice.Outlook 回答1: This worked for me: Right click Dependencies and click
