CoreWiki throws Errors if only dotnet core 2.2 is installed

[cam-smith]

If you only have .Net Core 2.2 installed, CoreWiki will throw a lot of errors when trying to compile. There's no clear documentation online about how safe it is to install .Net Core 2.1 on top of .Net Core 2.2 (which is what I ended up doing - it worked).

Probable long term solution is to upgrade CoreWIki to .Net Core 2.2.

I created a fork and downloaded it from the Fritz source. I have the same problem - working on it now. I will try to install 2.1.

In VS 2018, right-clicked on the Solution itself, and opened Build Order. It indicates a sequence:

1. CoreWiki.Core - I manually and successfully cleaned and built.

2. CoreWiki.Data.Abstractions - I manually and successfully cleaned and built.

3. CoreWiki.Data.EntityFramework - I manually and successfully cleaned and built, but with warnings:

   • ApplicationDbContext.cs(48,43,48,58):
     Warning CS0618: 'SlugHistoryDAO.AddedDateTime' is obsolete:
     'This property only exists for EF serialization purposes'

   • Repositories\SlugHistoryRepository.cs(39,5,39,18):
     Warning CS0618: 'SlugHistoryDAO.AddedDateTime' is obsolete:
     'This property only exists for EF serialization purposes'

4. CoreWiki.Notifications.Abstractions - I manually and successfully cleaned and built.

5. CoreWiki.Notifications - I manually and successfully cleaned and built.

6. CoreWiki.FirstStart - Failed.

   • StartupExtensions.cs(19,23,19,45):
     Warning CS0414: The field 'StartupExtensions._RunAfterConfiguration' is assigned
     but its value is never used.
   • StartupExtensions.cs(20,23,20,44):

   In the Areas folder, the Razor pages threw a warning first, then failed:
   ...Areas\FirstStart\Pages\Index.cshtml.cs(54,4,54,14):
   Warning MVC1002: 'HttpPostAttribute' cannot be applied to Razor Page handler methods.
   Routes for Razor Pages must be declared using the @page directive or using conventions.

   And: .nuget\packages\microsoft.aspnetcore.razor.design\2.2.0\build\netstandard2.0\Microsoft.AspNetCore.Razor.Design.CodeGeneration.targets(161,5): error : Assembly location for Razor SDK Tasks was not specified. The most likely cause is an older incompatible version of Microsoft.NET.Sdk.Razor, or Microsoft.NET.Sdk.Web used by this project.
   Please target a newer version of the .NET Core SDK.
