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

[ramnkl]

I tried to install Unicorn 3.0 RC
below is the nuget package details

We are in the process of the auto deployment process with unicorn. It would be more helpful for us to resolve this issue.

I have also tried with sample config which are included while install the nuget package.

Server Error in '/' Application.

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

[ramnkl]

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

[jsabra1]

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.

[muso31]

Thanks the items successfully appear here but it's not serializing item changes I make in Sitecore into VS (there is a predicate setup). They don't appear as pending changes in visual studio? I do have the correct message in Sitecore:

This item is controlled by Unicorn
Changes to this item will be written to disk as part of the 'Default Configuration' configuration so they can be shared with others.

[kamsar]

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

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.
