Speed up App Startup

[ted]

I have a legacy app that launches a C# app. It takes a long time for it to
launch the first time and after that it launches fine. I know it has to do
with the .net runtime. Is there a way around this? This app uses 1.1 .net
runtime.

Thanks

It take a while to compile the code into native machine language.. Remember,
when you "compile" your .NET application it does not create machine code,
but a byte-code type of language that still needs to be converted into
machine specific code when it is ran for the first time.

The first time it loads, the .NET framework libraries have to load from
disk. After that, they're probably cached. I suspect that if you leave
your computer for a few hours (and do other things) then start the app
up again, it'll be slow again.

Hello Ted,

have a look a this web page

http://www.codeguru.com/Csharp/.NET/...php/c4651#more

It's about the ngen.exe tool included in the .NET Framework. It could help
to improve application load time...

Bye
