Info

In case you install WireMock.Net in a project which also uses another dependency which uses Microsoft.CodeAnalysis.CSharp, you get an error.

Error

NU1608: Detected package version outside of dependency constraint: Microsoft.CodeAnalysis.CSharp.Workspaces 3.3.1 requires Microsoft.CodeAnalysis.CSharp (= 3.3.1) but version Microsoft.CodeAnalysis.CSharp 3.4.0 was resolved.
NU1107: Version conflict detected for Microsoft.CodeAnalysis.Common. Install/reference Microsoft.CodeAnalysis.Common 3.4.0 directly to project ConsoleApp1x to resolve this issue. 
 ConsoleApp1x -> CS-Script.Core 1.3.1 -> Microsoft.CodeAnalysis.Scripting.Common 3.4.0 -> Microsoft.CodeAnalysis.Common (= 3.4.0) 
 ConsoleApp1x -> Microsoft.VisualStudio.Web.CodeGeneration.Design 3.1.1 -> Microsoft.VisualStudio.Web.CodeGenerators.Mvc 3.1.1 -> Microsoft.VisualStudio.Web.CodeGeneration 3.1.1 -> Microsoft.VisualStudio.Web.CodeGeneration.EntityFrameworkCore 3.1.1 -> Microsoft.VisualStudio.Web.CodeGeneration.Core 3.1.1 -> Microsoft.VisualStudio.Web.CodeGeneration.Templating 3.1.1 -> Microsoft.VisualStudio.Web.CodeGeneration.Utils 3.1.1 -> Microsoft.CodeAnalysis.CSharp.Workspaces 3.3.1 -> Microsoft.CodeAnalysis.Common (= 3.3.1).
Package restore failed. Rolling back package changes for '***'.

Analysis

The problem is that the last dependency (Microsoft.CodeAnalysis.Common) uses a different FIXED version.

Solution

In order to fix this, you need to find out the dependency which uses Microsoft.CodeAnalysis.Common, in this example it's Microsoft.CodeAnalysis.CSharp.Workspaces.

So you need to reference the 3.4.0 version from Microsoft.CodeAnalysis.CSharp.Workspaces in your main project.

When that's done, you can use CS-Script.Core and that other library.
