There is very little point in targeting the client profile for .NET 4.0. The download is 41MB, the full version is 48MB, only 15% bigger. The client profile does make a lot of sense if you target 3.5, the full installer is ~350 MB. The huge difference is explained by the prerequisites, .NET 4.0 requires … Read more
It seems performance counters were corrupted on my system. Although I didn’t follow this post exactly, it led me to the solution. Here is what I did: In an command prompt with administrator/elevate privileges typed the following: lodctr /? Useful stuff in there… Then typed: lodctr /R According to the docs from the prior step, … Read more
In .net 4.0 Microsoft removed the ability to add DLLs to the Assembly simply by dragging and dropping. Instead you need to use gacutil.exe, or create an installer to do it. Microsoft actually doesn’t recommend using gacutil, but I went that route anyway. To use gacutil on a development machine go to: Start -> programs … Read more
Redundancy, when the first source is corrupt it gets validated or synchronized with the other.
I’m having the same issue. At approximately 8-10 hours of application life CLR error rises. I suspected my unmanaged code generating exception in the background thread. However I could not really find out why. You can give the following a try however: If you are using unmanaged code review exception handling statements while executig it. … Read more
According to documentation: If two string objects are equal, the GetHashCode method returns identical values. However, there is not a unique hash code value for each unique string value. Different strings can return the same hash code. Thus, some other effect must be in play for the two calls to give different results. One theory … Read more
Yes, there are risks of the sort you describe. The .NET 4.0 interface is unchanged, so if you target .NET 4.0, your program will compile and run on XP with .NET 4.0, but the .NET 4.5 implementation of .NET 4.0 contains bugfixes as well. If you rely on .NET Framework not being buggy, and the … Read more
In your first example, the as operator attempts to use the object s as an int?. Since int? isn’t anywhere in the inheritance chain of short?, this operation fails. In your second example, you’re actually creating a new int? i with the value from short? s. This is a more generous operation, because it doesn’t … Read more
You can use the Linq methods that are defined in the System::Linq namespace, but you’ll have to jump through a couple extra hoops. First, C++/CLI doesn’t support extension methods. However, the extension methods are regular methods defined on various classes in System::Linq, so you can call them directly. List<int>^ list = gcnew List<int>(); int i … Read more
CurrentManagedThreadId is a .NET 4.5 property, so you will need 4.5 to run the code. See Iterator blocks, missing methods, and .NET 4.5 for an analysis of how this problem might occur. In short: If you build your application (targeted at .NET 4.0) on a system with .NET 4.5 installed, it will use 4.5 as … Read more
