Some kind of IPC?

Try memcache.

thank you - I don't know of dotnet clients for memcache. But yet - it needs a server. Any native dotnet cache out there?

GAC objects are shared by all processes of the same machine, so that could be your approach.

I'm searching for a managed shared memory where I can put a global dotnet-object (meaning class instances) cache...

first check this link: http://en.wikipedia.org/wiki/Global_Assembly_Cache

if you can take a bunch of the app code and put it into dlls that will not need to change very often then you can put them in the servers .net GAC and then each copy of the app you may install does not need a local copy of the dll.

for example if you wanted to use ClickOnce to give each user a local copy of the app in terminal services then by using the GAC each users copy of app code is reduced.

mmh, that doesn't answer the question. Hard disk space is no concern. The question is how can I achieve dll sharing in memory.

for sharing data between sessions my first choice is to use a database, that's what they are for is storing and fetching data.

most of the time when folks try to create a "better storage" they do not. the folks who write SQL server or Oracle have spent decades on performance....

how big is the data to share ?
what kind of data ?
where does it come from ?
how many users need to see it?

each of the above could guide the design of the data store.
in some cases you may want a shared memory cache but most of the time a good SQL DB will get you as good a perf with a lot less code work, and testing and so on...

I've got a database backend but we also need a local cache in memory. Loading a few thousands rows and converting it to objects takes a while. Just think about SQL roundtrip time...

Hello,

I'm currently developing a large application which is run on a Terminal Server by multiple users currently.

How can I achieve low memory pressure? E.g. how can I achieve that the dll's will be shared?
Do the assemblies have to be signed? Do they have to be in the GAC?
I already know that the base adress must be set correct or otherwise they will be rebased (which leads to non-shareable dlls)..

Anyone know a solution for a global (spanning multiple TS sessions) dotnet-object cache?

Coffeehouse - MSDN and Microsoft sites in general

Hi,

hidden info isn't the only problem..
A few weeks ago I called MS-Action-Pack-Support (in Germany) because I want to get details about buying it as Microsoft Certified Partner and they told me that the known that the German-Partner-Sites are old and contain wrong information..

Till now nothing has changed and I have to get the information from the international-partnerpages..

Coffeehouse - Hall of Technical Documentation Weirdness

Hi,

The Hall of Technical Documentation Weirdness is pretty cool. They list wacky, bizarre, surreal and otherwise strange examples of technical documentation, particularly illustration.

I could post lot of translation-errors for the german VS.Net and MSDN - but that's not fun anymore -> causing many bugs

That would be my wish if I haven't changed to the english VS.Net: let developers (or someone how to changes a little bit about developing) do the translation!

1.) We are listening and taking in your bug reports. Things need to get better in many areas from UI, to HTML quality, to random bugs. We will post our next actions on the site on Wednesday. Help us prioritize.

and where should we post our bug reports?

I don't know any public MS-Bugtracker and just mailing them to MS seems to me no good idea -> I don't know what was already posted and most likly only send duplicates..

If we should post them here, a bug-forum would be great!

Coffeehouse - Integration of VSS with VS.NET

Jtb — Wed, 07 Apr 2004 18:50:18 GMT

Hi,

a "new" SourceSafe would be really great!

-> Very slow at fetching projecthistory
-> Databasehandling isn't very good: maximum size (3-5GB), always check for enough free diskspace, need to be analyzed very often (see http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnvss/html/vssbest.asp)
-> Switching between online/offline is very slow (VS.Net)
-> VSS over VPN is very slow
-> no Webclient
-> Not fully integrated into VS.Net (renaming files..)
