Frans Bouma announced recently the release of a new cool product. The ORM Profiler v1.0.

These days ORM is common place in almost all types of Projects. But the extra level of abstraction from the database comes at a cost: Performance. Do you have any idea on what’s going on behind the scenes? When you do a simple LINQ query, do you have any concerns about what’s going to be projected to the database? If you do care, then take this tool for a spin.

Frans Bouma anunciou a alguns dias o lançamento de uma nova ferramenta. O ORM Profiler v1.0.

Hoje em dia usar alguma forma de ORM é normal em quase todos os tipos de projectos. No entanto o nível extra de abstração tem um custo: Performance. Fazes alguma ideia do que acontece por trás da cortina? Quando se faz um query LINQ simpes, tens alguma preocupação com o que vai ser projectado sobre a base de dados? Caso tenhas, então testa esta aplicação.

Many may not been aware but there have been major changes on the Mono project, specifically, the team was laid off across all countries after Attachmate came into scene.

Icaza started a new startup to continue the project. The question is… will it live on?

Mono success had a lot to do by being associated with respectable distro like OpenSUSE and Novell. As soon as another company came to the scene and bought Novell, Mono was canned. If Attachmate decided that Mono was not important, it was probably because the cost of the project was much higher than the advantages and the revenue that it provided. if that’s the case, how does Icaza plans on making it work by “himself” on a new startup? What does Icaza knows that Attachmate didn’t?

At the same time as some may know, Microsoft bought through CPTN Holdings LLC, a substantial amount of IP from Novell (if I recall with a price tag of over 400 million). Is it just me or did Microsoft lost an amazing opportunity back then to get Mono? Mono as a project is really interesting to the .NET community, because it allows us to have the option to code to multiple OS platforms. Recent developments on the mobile area makes Mono a interesting tool to keep an eye on. iOS and Android support is something that as a developer interests me. Code one, deploy on different systems. How perfect would it be to have this under a single platform with Microsoft supporting it?

Back to my first question is… will Xamarin be able to cut it and continue to develop Mono? I hope so.

Exactamente ppl. Finalmente, e depois destes anos todos, o VB.NET finalmente passa a ser suportado no XNA.

Cada ano que passa a estratégia da MS em relação ao VB.NET parece é cada vez mais uma maior paridade com o C# a todos os níveis, inclusivamente nos SDK mais recentes. Também tem sido feito um esforço muito grande por parte da MS na área da documentação e em lançar sempre exemplos nas duas linguagens.

Cada vez mais a escolha da linguagem é realmente apenas uma escolha.

Já agora, não há ainda downloads nem links. O que há é um anúncio no DevConnections do Dave Mendlen.

Visual Studio Lightswitch Beta 2 was released with a Go Live license.

This means that, because it’s included a Go Live license, we are now with a version that is good enough to start building products that will be upgradable to newer versions of VSLS with minimum if any breaking changes.

Lets turn the Switch on ppl.

Visual Studio Lightswitch Beta 2 foi lançado com uma licença “Go Live”.

Isto significa que, porque estamos perante a inclusão da licença “Go Live”, podemos agora começar a desenvolver aplicações que serão passívels de ser actualizadas para versões mais recentes do VSLS com poucas se algumas alterações que causem problemas.

Toca a acender os interruptores ppl.

Não está directamente relacionado com programação mas não deixa de ser uma ferramenta importante, principalmente para quem tem de gerir vários servidores com aplicações / websites.

SQL Server Compact 4.0 is available for download.

SQL Server Compact 4.0 has been optimized for use with ASP.NET websites. It supports up to 256 connections for a single database and up to 4GB database file sizes. This is makes it capable of handling the load that a starter website requires. We already have CRM’s like mojoPortal, Umbraco, and others supporting it.

As requirements grow, moving from SQL Server Compact 4.0 to SQL Server may be needed for higher availability. Doing so, its easy using the WebMatrix IDE.

Also, SQL Server Compact 4.0 is the default database format for projects on the recently released Microsoft Webmatrix.

This release supports private deploy scenarios. This means that just by copying a a few DLL files to your app folder, you can use SQL Server Compact 4.0 with minimum deploy effort.
