  - by paul.moore.name

  I'm considering writing a console application in C# and I want to incorporate history, completion and command line editing features something like GNU readline (but not necessarily as extensive as that!) Is there an existing library for .net which provides this type of functionality? I guess one option would be to use interop services to call GNU readline. But is there a native option?

• How do I diagnose a failure in the Membership service on an ASP.NET remote site?

  - by ProfK

  Yesterday I added a custom MembershipProvider to an ASP.NET web application, but when I deployed the application to its remote host server, it failed. I know I had the login info correct, and I also know that for nearly any exception in the login process, the Login control displays the standard error message, "Your login failed", so I assume something is wrong in the code/config. What can I do to diagnose what is wrong on the server?

• Can the .NET MethodInfo cache be cleared or disabled?

  - by Anton

  Per MSDN, calling Type.GetMethods() stores reflected method information in a MemberInfo cache so the expensive operation doesn't have to be performed again. I have an application that scans assemblies/types, looking for methods that match a given specification. The problem is that memory consumption increases significantly (especially with large numbers of referenced assemblies) since .NET hangs onto the method metadata. Is there any way to clear or disable this MemberInfo cache?

• Is there a standard dialog for constructing an ADO.Net connection string (that is redistributable)?

  - by rathkopf

  I want to use a standard dialog to solicit user input of an ADO.net connection string. It is trivial to do for the oledb connection string as described here: MSDN Article on MSDASC.DataLinks().Prompt I've also found examples that use Microsoft.Data.ConnectionUI.dll and MicrosoftData.ConnectionUI.Dialog.dll from VS (HOWTO: Using the Choose Data Source dialog of Visual Studio 2005 from your own code). Unfortunately these DLLs are not licensed for redistribution. Is there a standard dialog for choosing a data source that can be distributed with my application?
