I'm confused about the purpose of the CLS (Common Language Specification) in the .NET Framework. My understanding is that, with .NET, we can write a library with one language and use it in another language, and that the CLR enables this functionality.I do know that the purpose of the CLS is to fully interact with other objects regardless of the language they were implemented in.icrosoft has defined the Common Language Specification (CLS) that details for compiler vendors the minimum set of features their compiler must support, if these compilers are to generate types compatible with other components written by other CLS compliant languages on top of the CLR.
In the above graph the cost of homeschooling using different styles only varies by $900 dollars, the range being from $1500-$2400. School fees for the first child can cost, $0 to $300 in a public school and $12000 to $22000 in a private school. You also need to add extra for special events, excursions and uniforms.
(Building from scratch obviously will cost much more.) Hard assetsâplaygrounds, toys, couches and cribsâshould run between $300 and $400 per child. You may also need to shell out a few extra months in rent and directorsâ salaries, as well as training for staffers.nce your center is up and running, payroll to meet mandated staff-to-child ratios is your largest line item, gobbling roughly 70% of sales. State laws vary, but in general you need about one staff member per 12 preschool-age children; one per six children ages 2 to 4; and one per every four infants.
