There are many reasons why this is attractive both to the developer and to companies in general. Scala is a concise and highly productive programming language. By using Scala on .Net, developers can produce applications more quickly and have the possibility of deploying them across the two major industry platforms, JVM and .Net.

For the programmer it makes a great deal more sense too, learning one language to build applications for both environments. From a company point of view scarce resources, good developers, can be moved easily between platforms reducing training costs, increasing flexibility and reducing risks. .Net provides an integration platform for several languages and this implementation of Scala inter-operates nicely. You can use existing .Net libraries or applications without re-writing everything in Scala. A low risk way to explore the potential of Scala. Ultimately it means that many tools and applications created for the .Net and JVM environments can be ported from one to the other. A win-win situation for everyone.

Yea, that'll be interesting, shimming to another shim (IKVM) and dismissing the standard .NET collections (hello, interop?) doesn't fill me with hope for performance, which is one of the main reasons to use Scala.

Not sure why they are much better, but the .net framework collections were always a little strange.

Also can't Scala be generic on both parts  M<T> ,  T and the M,

Immutability/mutability is but one axis:

Source: http://www.scala-lang.org/docu/files/collections-api/collections.html

The following figure shows all collections in package scala.collection. These are all high-level abstract classes or traits, which generally have mutable as well as immutable implementations.

The following figure shows all collections in package scala.collection.immutable.

And the following figure shows all collections in package scala.collection.mutable.

(All three figures were generated by Matthias at decodified.com).

I don't know if Scala has something like LINQ though, in particular IQueryable. Apart from this, a prime concern would be performance.

http://www.scala-lang.org/docu/files/collections-api/collections_3.html

the collections api was the major feature of Scala 2.8, very advanced stuff

http://www.artima.com/scalazine/articles/scala_collections_architecture.html

and parallel collections was a major feature of Scala 2.9

Reminds me of the STL. When will .net developers get nice collections like that?
