Can a LINQ enabled app run on a machine that only has the .NET 2.0 runtime installed? In theory, LINQ is nothing more than syntactic sugar, and the resulting IL code should look the same as it would have in .NET 2.0. How can I write LINQ without using the .NET 3.5 libraries? Will it run on .NET 2.0?...
On a quest to migrate some new UI into Managed/C# land, I have recently turned on Common Language Runtime Support (/clr) on a large legacy project, which uses MFC in a Shared DLL and relies on about a dozen other projects within our overall solution. This project is the core of our application, and would drive any managed UI code that is...
I've got a problem similar to,but subtly different from, that described here (Loading assemblies and their dependencies). I have a C++ DLL for 3D rendering that is what we sell to customers. For .NET users we will have a CLR wrapper around it. The C++ DLL can be built in both 32 and 64bit versions, but I think this means we need to have...
I'm trying to programmatically restrict the memory consumption of plugins running in a .Net AppDomain, but I can't find any setup parameters for this, nor can I find a way to query an AppDomain to figure out how much memory it is consuming. Any ideas? ...
I would like to use something like CLR Profiles on .Net 2.0 to see what objects are taking more space in the heap at any given time (of an ASP.Net worker process). However, the CLR Profiler only lets me START an app, not attach to an existing one. I assume this is because it tracks allocations and GC too, but i'm not very interested in ...
What's the difference between the inner workings of Java's JVM and .NET's CLR? Perhaps a starting point would be, are they basically the same thing in their respective environments (Java > JVM > Machine code) (C# > CLR > IL). Update: Several people have alluded to the points I was trying to cover: Garbage Collection Boxing/Unboxi...
I was wondering if there's any way to change the behavior of the .NET JIT compiler, by specifying a preference for more in-depth optimizations. Failing that, it would be nice if it could do some kind of profile-guided optimization, if it doesn't already. ...
Let's say we have the following method declaration: Public Function MyMethod(ByVal param1 As Integer, _ Optional ByVal param2 As Integer = 0, _ Optional ByVal param3 As Integer = 1) As Integer Return param1 + param2 + param3 End Function How does VB.NET make the optional parameters work within the confines of the CLR? Are...
I have a Windows/Linux Qt 4.3 application that uses drag and drop in a QTreeView. I have two very similar applications which use the same set of Qt libraries. Drag and drop works in both on Linux but in only in one on Windows. In the application that does not work the QDrag object gets deleted as soon as the mouse is moved. I...
Is there a generic way, without creating and managing your own CLR host, to take over locating and loading a type if that type is not found? The following is just an example. In your rush to be the first answer, don't suggest the new add-in framework or the MEF as a solution to my question. An example would be a sample with add-ins. ...
We are using SQL 2005 and the try-catch functionality to handle all of our error handling within the DB. We are currently working on deploying a .NET CLR function to make some WCF calls in the DB. This WCF procedure is written in the CLR and then deployed to SQL. If I put a try-catch block in the CLR code, it catches the error fine. Howe...
We're deploying some new WCF calls in our SQL 2005 DB using the CLR. In testing, I hardcoded in the code the endpoint to connect to, and deployed it to our test server. When we go to deploy this to production, we will be deploying it to many different SQL DBs, and using different endpoints to connect to (same service running on different...
I'm well aware of Java tools for manipulating, generating, decompiling JVM bytecode (ASM, cglib, jad, etc). What similar tools exist for the CLR bytecode? Do people do bytecode manipulation for the CLR? ...
Everything I have read says that when making a managed stored procedure, to right click in Visual Studio and choose deploy. That works fine, but what if I want to deploy it outside of Visual Studio to a number of different locations? I tried creating the assembly with the dll the project built in SQL, and while it did add the assembly, i...
When Joel Spolsky and Jeff Atwood began the disagreement in their podcast over whether programmers should learn C, regardless of their industry and platform of delivery, it sparkled quite an explosive debate within the developer community that probably still rages amongst certain groups today. I have been reading a number of passages fro...
Is it possible to reference a .NET Assembly from a SQL Server Stored procedure or function, or otherwise access the clr code from SQL Server? EDIT Whilst this solution will require to be somewhat generic, I am fairly confident expecting SQL 2005+ ...
We're considering writing the next version of out project in using .Net 3, but are wondering if we can take the hit on forcing end users to install the .net framework version 3. ...
In Jesse Liberty's Learning C# book, he says "Objects of one type can be converted into objects of another type. This is called casting." If you investigate the IL generated from the code below, you can clearly see that the casted assignment isn't doing the same thing as the converted assignment. In the former, you can see the boxing/un...
I'm looking for good resources to learn and contribute to regarding CLR profiler API knowledge (a.k.a "Extended Reflection"). Got one? Only other question here islink text but it's just a beginning. ...
Will .Net 4.0 use a new version of the CLR (v2.1, 3.0) or will it stick with the existing v2.0? Supplementary: Is it possibly going to keep with CLR v2.0 and add DLR v1.0? Update: Whilst this might look like a speculative question which cannot be answered, the VS team appear to be releasing more and more info on VS10 and .Net 4.0 so th...
