I'm trying to run my app which includes some SignalR connections and other async methods.
As soon as the codes reaches
connection.StartAsync();
I get this Error:
System.TypeInitializationException: 'The type initializer for 'Microsoft.AspNetCore.Http.Connections.Client.Internal.Constants' threw an exception.'
Inner Exception: FormatException: The format of value '@BuiltBy: dlab-DDVSOWINAGE059 @Branch: release/2.1 @SrcCode: https://github.com/dotnet/corefx/tree/30ab651fcb4354552bd4891619a0bdd81e0ebdbf' is invalid.
This exception was originally thrown at this call stack: System.Net.Http.Headers.ProductInfoHeaderValue.Parse(string) Microsoft.AspNetCore.Http.Connections.Client.Internal.Constants.Constants()
When running from VS all looks good and works fine.
So far, I have no clue.
Any ideas?
