Could not resolve type name: Unicorn.UnicornSqlServerDataProvider, Unicorn (method: Sitecore.Configuration.Factory.CreateFromTypeName(XmlNode configNode, String[] parameters, Boolean assert)). about unicorn

Check your ignores. Visual studio also has the nasty habit of not showing
changes outside csproj entries.

Thanks Kamsar, It worked after remove the serialization.config from app_config\include folder.

[kamsar]

Are you upgrading from v2? Because that type name is v2's data provider.

There are upgrading directions here; specifically, you may need to remove the data provider registration from the main unicorn.config/serialization.config and allow it to register from Unicorn.DataProvider.config instead.

[kamsar]

There are also clean copies of all the config files here

HI @kamsar . I am still having this issue, and deleting serialization.config doesn't seem like a sensible solution as it is required to point unicorn where to pull the data from? Because when i launch unicorn after deleting the file i get a message that there is no default configuration set for serialization, then if i do serialization anyways the project is still to the default content tee. Can you please provide any advice on this

[kamsar]

@jawsab Serialization.config is an artifact of Unicorn 2.x, and the configurations therein have been moved elsewhere. The upgrade guide will walk you through where to put things.

I just upgraded to unicorn 3.0. It works and writes files to disk (wwwroot) but in Visual Studio they don't appear as items to be checked in? There's no 'serialization' folder in the project anymore so where do they get written to? thanks

[kamsar]

The default in 3.0 is $(dataFolder)\Unicorn. There's a sample config that is included that demonstrates how to move the default.

Hi there,

I'm having the same issue with Sitecore 9.2.0 and unicorn 4.0.3. i tried to follow the workaround you described up there but some files are no longer available (because of version i guess). Any suggestionplease? Regards.

Error: Could not resolve type name: Unicorn.Data.DataProvider.UnicornSqlServerDataProvider, Unicorn (method: Sitecore.Configuration.DefaultFactory.CreateFromTypeName(XmlNode configNode, String[] parameters, Boolean assert)).

Definitely not the same issue.

Anyway, for Sitecore 9.2.0 the minimum required version of Unicorn is 4.1.0. Update to that, clean up your config clutter.

[jaimeyzv]

Actually, I used 4.0.30 for testing since the latest (4.1.1) is throwing the same error. Also, I just reintalled 4.1.1again, create the serialization solution again and, as I mentioned, I'm getting the same error.

Based on this, unicorn update is not the fix. Any other suggestion please.

[cassidydotdk]

Yea. Harsh as it sounds; clean up your config clutter :-) There's either DLLs missing in your target instance, or there are relic config files present in your target instance.
