I'm getting the following error while trying to run Http server in macos.

Application startup exception: System.PlatformNotSupportedException: The named version of this synchronization primitive is not supported on this platform.

I have tried to run the server on tag v0.3a and it worked completely fine.

@kreeben - Can you please take a look at it. I have some experience working with C# and I'm ready to help if you could guide me.

And I want to thank you for making this open source.

[kreeben]

Thx for the error report. I will have a look.

[kreeben]

I read on .Net Core's issue stream here on GitHub that they had fixed named synchronization on Unix/MacOs but because you were having problems I replaced them with plain 'ol locks: https://github.com/kreeben/resin/commit/4ffa49406ec895a18b589accd4127883026071fa

Patch applied to both master and dev. Please let me know if this fixed it for you. I don't have access to a Mac ATM.

[kreeben]

@kburman Once you get your dev environment going then I'd be happy have you join as a contributor.

[kburman]

@kreeben - I will test the new commit and would let you know.

@kburman Once you get your dev environment going then I'd be happy have you join as a contributor.

Sure, Right now I'm exploring the codebase, once I get little familiar with it. Would like to contribute to the project.

[kburman]

I have tested the master branch, It's working fine but I'm getting some error on the dev branch.

Steps to reproduce

• Switch to the dev branch
• Empty the app_data folder
• Add a URL to crawl from web ui
• Search any key term.

[kreeben]

Could you perhaps also give me the URL you tested with. Either way, I'll take a look ASAP.

[kreeben]

This https://github.com/kreeben/resin/commit/f596130a72d86a3d301766273bea4380200633cb fixed it for me. If you pull from dev branch you should be good.

[kburman]

Can confirm, It's working for me.
