Is it possible to load a referenced assembly only if the .NET Framework version is lesser than a specific number? I'm using a selfmade LINQ library on .NET 2.0, but if the framework is 3.5+, it should use the M$ LINQ library, and ignore the selfmade one.
Here's my library: [URL]
I have this situation where LoadWithPartialName appears to be the only good alternative, although it is marked as Obsolete. I work in a very tight dev environment with versioning and deployment policies that cannot be easily changed or bypassed. Let's say there's a .NET executable that I have no control on (from another division). Let's call this the client AppA application. AppA's version is 10.11.12.x. Application AppA has a direct reference to one of our class library that provides some service to the caller (returns some information).
Let's call it SvcB and the version is also 10.11.12.x. Now, AppA's division does not need to update their system as often as we do, so AppA's version will stay 10.11.12.x for some time, probably until we decide to change the format of the class that is exchanged between us. Our division needs to change the logic behind the service SvcB more often and the version must change with every major deployement.
So let's say we change the logic and we deploy a new version of SvcB, 11.02.11.x. AppA will still reference the old version, so the logic being used is now incorrect. We are thinking of creating a new "facade" to our service. Let's call it SvcFrontB. SvcFrontB's version will stay the same, in sync with the AppA's own version. Now I need SvcFrontB to load the most recent version of SvcB through reflection. This way, I am sure the latest logic is always used. How do I achieve that without using LoadWithPartialName ?

I am loading an assembly using LoadFrom method on a file located in another folder. The assembly is called VisualCronAPI.dll. The assembly that I load has references to another assembly (VisualCron.dll) which contains some general type definitions used in VisualCronAPI. The file VisualCron.dll resides in the same folder as isualCronAPI.dll.When using LoadFrom I see in the output that VisualCron.dll is loaded. I am able to retrieve all methods in VisualCronAPI that uses parameters from VisualCron.dll. I am able to see parameter values However, when trying to create a Type using the following code I get an exception:
Dim t As Type = assem.GetType("VisualCron.NetworkCredentialClass, true)
Exception: Could not load type 'VisualCron.NetworkCredentialClass' from assembly 'VisualCronAPI, Version=1.0.3.32487, Culture=neutral, PublicKeyToken=55f7a52402de1c04'.

Since, it's possible for anyone to name an assembly starting with 'System', checking for 'System' is not a satisfactory solution.
Alternatively, if that's not possible, how about checking the modules in an assembly?
I receive this error as "Assembly Load Error" whenever adding a form or other object that has to be inherited.
"Unable to load assembly. Ensure that the file is a valid .net Framwork assembly"

View 4 RepliesOne of them is giving us trouble in only 1 spot out of the 4 spots we use it at:The trouble spot is a windows form project that uses reflection to dynamically load some DLLs that run long running processes. One of these long running processes is an agent that relies on one of our vender DLLsWe're getting the missing assembly exception at the point where we first enter a function that references the library. I already checked the silly things such as if we had forgotten to move a reference from the old version to the new version, but that's not the case. I also checked the bin directory of the project and the assembly is there.
View 3 RepliesI have dll and exe files which have assebly version numbers different from the values stored in AssemblyInfo.vb.If I look at the information displayed in the Details tab of File properties in Windows, the File version and Product version values are identical with the values of AssemblyInfo.vb. But when I use My.Application.Info.Version to display the version number at runtime, the value displayed is incorrect. Also when I add a reference to a dll file, the referenced version is incorrect. The incorrect value is the same as the value last time AssemblyInfo.vb was edited on the local machine. If the AssemblyInfo.vb file is edited on another machine, the value won't be updated on other machines.
Typical example: On a nightly build the build server increments the build number of all AssemblyInfo.vb files. When developer workstations are updated in the morning (get latest) the build number isn't updated at runtime - even though the AssemblyInfo.vb file is updated and compiled into a new dll or exe file. But file properties in Windows displays the updated build number as described above. I've been looking for other places where a version number might be stored (in case there are more than one place to update the version number), but I can't find any reference to the displayed build number when I search the source files.
If a developer workstation edits the build number, compiles, and edits it back to the correct value and builds again, the displayed value at runtime is equal to the value in the source file. It's like the AssemblyInfo.vb files must be edited on the machine that builds the solution, or the result is not reliable..
I would like to get latest version of the assembly. how?

View 2 RepliesI have a stand-alone WinForms application, let's call it "Program A." Program A let's a user create a file and save some information to it. Program A also exposes some public classes.Another stand-alone WinForms application ("Program B") references Program A, and uses some of its public classes.
However, some of Program A's classes need to open the file the user created in order to retrieve data from it. In Program A, the location of the user's file is saved in the "Settings" (as user-scope settings of course) and are retrieved (this is a VB.NET app) via My.Settings.
This is all well and good until Program B runs - when it runs and uses the classes from Program A that need to read from Program A's My.Settings, the settings are blank - it's as if they were reset (as when you run Program A for the first time or under a new user account). Any application-scope settings are kept, but any user-scope settings are reset to their default values (whatever they were set to in the IDE when Program A was written).
[Code]...
Assume that the user has already run Program A at least once and opened a file, so Program A's My.Settings.UserFileName should be set.
When Program B calls Foo.GetStuff(), it doesn't return anything because My.Settings.UserFileName doesn't contain the user's file name - more accurately, it contains whatever the "default" value for that setting was (as set in the IDE when you set up the setting in the first place). But, if you turn around and launch Program A, it remembers the user's setting for UserFileName.
So - the question is: When calling a function in a referenced assembly, why are the user's settings not retained? Is there an explanation for the behavior I'm seeing, or am I missing something terribly obvious? Or perhaps I'm just going about this all wrong, and I shouldn't have made any of the public classes in Program A rely on anything in My.Settings in the first place?
All of the sudden, I'm no longer able to build a Solution without getting an error in VS 2010. A minute ago I was able to build, and now I can't.
The error is:
Unable to load referenced library 'C:Program FilesReference

I've checked and the .dll is there. I've re-booted and grabbed the latest version from Team Foundation Server.
I've seen a lot of the "auto version" update add-ons for VS, and well I decided to write one for myself. It's manually triggered, but put as a external tool in the IDE it works rather nice. I based it off of reading the AssemblyInfo.vb file for a project (so at the moment it only works in VB not C#). So my app (given certian parameters) will auto increment the FileVersion and Assembly version together, so they stay the same through out. (it simpler for me that way). But i noticed a little issue with this method of reading the assemblyinfo.vb file, changing the values and saving the file and then forcing a "Rebuild" of the project.
When I go to Explorer, right-click | Properties on the file, in the Version tab, the "AssemblyVersion" has not changed, where the Product and File Version has. so for example I've got Test.Exe I open up the project properties and set via the UI the versions to:
