System.Io.FileLoadException: BCrypt.Net-Next

[Revyn112]

With the update of netcore 3.0 to version v3.0.0-rc1 BCrypt.Net-Next gives sometimes this error:

Unhandled Exception: System.IO.FileLoadException - System.IO.FileLoadException: Could not load file or assembly 'BCrypt.Net-Next, Version=3.1.3.0, Culture=neutral, Publi

That's an odd one. Any specifics of the solution or a small repro would be handy.

Ill release a new build later with support for 3

Looks like 3 will be as much fun as 1 and 2 😂

https://www.nuget.org/packages/BCrypt.Net-Next/3.2.0

I've built 3.2 against netstandard 2.1 for NetCore3; tests pass on my test rig, but the automated ci (appveyor) doesnt support the RC yet.

Its hard to reproduce, because this error comes only sometimes, after a restart of the application there is mostly no problem.

[Revyn112]

I'll test it and provide feedback ;)

Thanks also note the SO mention.

You must use exactly the same .NET Core, ASP.NET Core, etc. Make sure all packages from dotnet or aspnet are rc1 as for now. If some dependencies (including direct and indirect) in your project depend on any 2.2 packages that are from dotnet or aspnet and has a 3.0 new version, reference them as 3.0 rc1 version from your own project explicitly.

I know my machine was a hot mess of previews when I was dealing with DNX/V1/V2 😆

Hi Chris,

we found out, that the problem is not related to BCrypt itself :D but thanks for your fast answer and netcore 3 support!

Issue:
FabianTerhorst/coreclr-module#58

Cool; the type of exception seemed unlikely to be related, but hell you never know with a major release.
On the upside you pushed me to sort the netstandard 2.1 bit 👍
