System.ArgumentException: The modelEntityContainerName parameter contains characters that are not valid

Question

I've tried to use Entity Frameworks Power Tools Reverse Engineer Code First for a SQLServer database and received the following error:

System.ArgumentException: The modelEntityContainerName parameter 'testContext' contains characters that are not valid.
    at System.Data.Entity.Design.EntityModelSchemaGenerator..ctor(EntityContainer storeEntityContainer, String namespaceName, String modelEntityContainerName)
    at Microsoft.DbContextPackage.Handlers.ReverseEngineerCodeFirstHandler.ReverseEngineerCodeFirst(Project project)

Is there something I can do to continue or avoid this error or work around it.

Thanks.

Answer 1

I had the same problem. My database was named sots-version-005, and the code was not escaping the name. The answer is to rename the database, and hopefully you are in a development environment where that is easy to do.

I used SQL Management Studio, right-clicked on the database, and renamed it 'sots5', eliminating all characters except alphanumerics.
