The modelEntityContainerName parameter ...not valid

When using the Entity Framework and using the Reverse Engineer of the Entity Framework Power Tools Beta 2 if your database has invalid characters in the database name such as:

• Hyphen
• Period
• Any special character

For example, the database name was LittleShopOfHorrors-Dev contains a hyphen.  When running the Reverse Engineer you get the following error using Entity Framework 5:

System.ArgumentException: The modelEntityContainerName parameter 'PDShopLittleShopOfHorrors-DevContext' 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)

So, how do you get around it?

• Rename the database to use an underscore instead
• Do a Code First another way, such as building your models and using the model builder.
