• Is there a common practice how to make freeing memory for Garbage Collector easier in .NET?

  - by MartyIX

  I've been thinking if there's a way how to speed up freeing memory in .NET. I'm creating a game in .NET (only managed code) where no significant graphics is needed but still I would like to write it properly in order to not to lose performance for nothing. For example is it useful to assign null value to objects that are not longer needed? I see this in a few samples over Internet. Thanks for answers!

• How do I access the ASP.NET Configuration Tool when a site is live? This is ASP.NET MVC.

  - by Mike Marks

  I was wondering if it's possible to access the ASP.NET Configuration Tool once a site is live. To be able to create and edit users and roles is obviously very important, and from what I've been reading, once a site is deployed, the Configuration Tool is no longer accessible. If this is the case, HOW do I add users, etc.? By the way, I found a User Management plugin which brings a lot of the Configuration Tool's capabilities to the front end of a User Management section of the deployed website, but it DOES NOT offer the capability to add a new user. Help??? Thanks!!

• Where can I get some information on starting C# programming with MVC / ASP.NET?

  - by leeand00

  I'm a Java developer looking to learn some C#/ASP.NET. One thing I've never liked about .NET from the get-go was that it didn't have support for MVC. But now it does! So I was wondering if anybody knew where to get started learning C# MVC. Also, do you need the non-free version of developer-studio to do this?

• Is there any difference between Spring and Spring.net?

  - by Javi

  Hello, I've been using Spring with Java and I've seen that there is a version called Spring.NET.

• What is the list of trace sources supplied by the .Net framework?

  - by JoshL

  .Net defines a "Trace Source" concept, allowing configuration files to specify which trace sources to listen for messages on. WCF provides several trace sources, and I would presume that other portions of the .Net Framework BCL publish other trace sources as well. What is the list of trace source names published to by the BCL?

  I've been looking at software activation systems for .NET and frankly found the websites out there underwhelming. I'm wondering if there's a "standard" way to do it in .NET? If not, does anyone with experience of them have a recommendation? I understand the arguments for and against activation systems, but still need to evaluate. Thanks.

• Why so many ASP.NET programmers play with Ruby on Rails after working hours?

  - by ITmeze

  I saw that on so many blogs. Lots of the people that were dealing with ASP.NET tend to play with Ruby on Rails after working hours. And It is just a matter of last one or two years. Why is it like that? Is it because when ASP.NET MVC showed up people become more open-minded - having joy with programming again they realize that some other folks had that many years ago, and they do not want to miss what they currently have?

• Where can I write a temp file from ASP.NET?

  - by ProfK

  I have an 'access denied' problem on an ASP.NET web application, where the user uploads an Excel file and I try and write it to a folder. I don't have access to the host except FTP, so I can't set permissions. I thought that ASP.NET would be able to write to a folder that is under the web app root, but it isn't so. Is there anywhere I can write the file to that doesn't require me to set permissions?
