One really annoying bug yet to be solved on a fresh install of Umbraco from NuGet in Visual Studio is the following build error:
CSC : warning AD0001: Analyzer 'Microsoft.CodeAnalysis.CSharp.Analyzers.FixAnalyzers.CSharpFixerWithFixAllAnalyzer' threw an exception of type 'System.TypeInitializationException' with message 'The type initializer for 'Microsoft.CodeAnalysis.Analyzers.FixAnalyzers.FixerWithFixAllAnalyzer`1' threw an exception.'.
This is really easily solved, 1 NuGet package needs updating to remove this issue, simply open Manage NuGet Packages go to the Installed tab and search for the following:
And them simply update to the latest version.
Hopefully they will roll this out as a fix eventually, I have raised this with them on their forums with no reply.
