ILMerge & Keep Assembly Name - dll

I need to merge some dlls and both the file name and assembly name need to be the same as for my main dll (mydll.dll). I also need the pdb file. How do I get this done?
Here are a few things I tried:
Just use ILMerge mydll.dll .... /out:mydll.dll
This fails with "Access to the path ...mydll.pdb is denied."
Rename mydll.dll to mydllTemp.dll and mydll.pdb to mydllTemp.pdb and then
ILMerge mydelltemp.dll .... /out:mydll.dll
This fails with "The pdb associated with ...mydlltemp.dll is out of date" I think this is because ilmerge looks at the assembly name to find the pdb, hence it looks for mydll.pdb which was renamed.
Rename mydll.dll to mydllTemp and then
ILMerge mydelltemp.dll .... /out:mydll.dll
This works without errors but when I attach the debugger to a process it does not trigger
ILMerge mydll.dll ... /out:mydlltemp.dll
rename mydlltemp.dll to mydll.dll and mydlltemp.pdb to mydll.pdb
Now I can attach the debugger to a process with breakpoints being triggered. However, the assembly name now is mydlltemp instead of mydll
So how can I get this to work AND have the original assembly name?

You didn't really mention is this is in the course of standard development or if this is part of a build process.
If it's for standard development, do you really need everything merged just to test things out?
If it's for your build process, you can have the output go to a different directory (which you will probably need to mkdir first) and then you can reuse the same assembly name.

merge to another directory, use /out:somedir\mydll.dll

Changing the version information of ironpython .dll assembly

I compiled a .dll file in ironpython, by using the following code:
import clr
clr.CompileModules('C:/example.dll', 'C:/example.py')
It essentially compiles the .py file to .dll.
The only problem with this is that it creates a file with no information about the Company, Language, File Version etc. In fact the File Version is always: 0.0.0.0.
I was wondering if there is a way to at least alter the File Version (change it to something other than 0.0.0.0). I googled and found a similar topic in here on stackoverflow.
I tried three methods:
1) One with Visual Studio (File->Open-> find .dll, Edit->Add Resource->Version click New. In the new Version tab, change FILEVERSION and PRODUCTVERSION)
2) Another one by using the Change version 2012 application
3) And third one by using: Simple Version Resource Tool for Windows 1.0.10
None of them worked.
For some reason looks like the structure of the .dll assembly created with ironpython is different than the .NET one created with VB or C#.
Does anyone know how to change the File Version from 0.0.0.0 to something else?
Thank you.
You can use the pyc.py file packaged into IronPython to compile your file into a .dll file. The file is located in the directory IronPython 2.7\Tools\Scripts.
If we open pyc.py for editing, you'll see the different things it can do.
pyc: The Command-Line Python Compiler
Usage: ipy.exe pyc.py [options] file [file ...]
Options:
/out:output_file Output file name (default is main_file.<extenstion>)
/target:dll Compile only into dll. Default
/target:exe Generate console executable stub for startup in addition to dll.
/target:winexe Generate windows executable stub for startup in addition to dll.
#<file> Specifies a response file to be parsed for input files and command line options (one per line)
/file_version:<version> Set the file/assembly version
/? /h This message
EXE/WinEXE specific options:
/main:main_file.py Main file of the project (module to be executed first)
/platform:x86 Compile for x86 only
/platform:x64 Compile for x64 only
/embed Embeds the generated DLL as a resource into the executable which is loaded at runtime
/standalone Embeds the IronPython assemblies into the stub executable.
/mta Set MTAThreadAttribute on Main instead of STAThreadAttribute, only valid for /target:winexe
/file_info_product:<name> Set product name in executable meta information
/file_info_product_version:<version> Set product version in executable meta information
/file_info_company:<name> Set company name in executable meta information
/file_info_copyright:<info> Set copyright information in executable meta information
/file_info_trademark:<info> Set trademark information in executable meta information
Example:
ipy.exe pyc.py /main:Program.py Form.py /target:winexe
One thing that I personally like to do is move pyc.py from the Scripts folder to the IronPython folder along with my python file as well.
Assuming you also do this, you would open command prompt as administrator and navigate to the IronPython folder.
cd "Program Files (x86)\IronPython 2.7"
Then you would want to compile your python file as a .dll and set the file version using pyc.py. To do that, you're going to want to type in:
ipy.exe pyc.py /main:example.py /target:dll /file_version:0.0.0.1
If you want to add a company name, and other items as well, you simply have to pass those option to the pyc.py script.
ipy.exe pyc.py /main:Program.py Form.py /target:winexe /file_info_company:Company

NUnit unable to load dll with String Key Name

I have a project in which I have some C# classes which I am building using csc in my ant script. I have also have written some unit tests which I want to test with NUnit2.6, My test class and actual class refer to one DLL which is compiled with String Key Name (.snk), if I install thi DLL in my GAC (gacutil /i myDLL.dll) everything works fine. As soon as I uninstall this DLL from my gac I get following error for all the test during the build when I try to run my test using NUnit;
Test Error : fromJDynTest1
[exec] System.IO.FileNotFoundException : Could not load file or assembly 'myDLL, Version=5.1.0.0, Culture=neutral, PublicKeyToken=c0409b584f86b2d6' or one of its dependencies. The system cannot find the file specified.
[exec] at fromJDynTest1()
...
...
Does anyone know how to resolve this. Let me know if you need any other information.
Thanks

The code you are testing cannot see the assembly in question when you place it in the gac it can see the assembly. You need to ensure that the code you are testing has the assembly in the bin directory when compiled (perhaps copy local is set to false in your project on the assembly reference).
The reason I am sure it is not a dependency (which is mentioned in the message) is because the situation is resolved when the assembly is placed in the gac. This error is not likely caused because the assembly is strongly named.
Failing that the test code refers to the assembly and that test code either doesn't have a reference or has the same problem (not in its compiled directory).
Would help if you posted the actual test or structure of the project.
.net locates assemblies as follows:
Determines the correct assembly version by examining applicable configuration files, including the application configuration file, publisher policy file, and machine configuration file. If the configuration file is located on a remote machine, the runtime must locate and download the application configuration file first.
Checks whether the assembly name has been bound to before and, if so, uses the previously loaded assembly. If it failed before it will fail again now.
Checks the gac. If the assembly is found there, the runtime uses this assembly.
Probes for the assembly (if you open up a .csproj file in a text editor you will see hintpaths, which try and help .net find the assembly).

Missing MySQL DLL?

I've recreated the Northwind Spring/NHibernate example that comes with Spring.NET, but with MySQL rather than SQLServer. I've almost got it working I think, but I'm getting this when I try to use Hibernate to load something from the database
A first chance exception of type 'System.IO.FileNotFoundException'
occurred in mscorlib.dll NHibernate.Util.ReflectHelper:
ERROR lambda_method - Could not load type
MySql.Data.MySqlClient.MySqlCommand, MySql.Data.
System.IO.FileNotFoundException: Could not load file or assembly
'MySql.Data' or one of its dependencies.
The system cannot find the file specified.
File name: 'MySql.Data'
Every project (DAO, Service, Web) has a reference to the MySQL.Data DLL so I'm a bit unsure what's going on.
Can anyone help me please?
Make sure that MySQL.Data.dll actually got copied to the output folder. And that you are using right platform (x32 vs x64 bit) and right version of .NET (2,3,3.5 vs 4). If everyhing seems fine, enable Fusion Logging and take a look at this article:
For FileNotFoundException: At the bottom of the log will be the paths
that Fusion tried probing for this assembly. If this was a load by
path (as in Assembly.LoadFrom()), there will be just one path, and
your assembly will need to be there to be found. Otherwise, your
assembly will need to be on one of the probing paths listed or in the
GAC if it's to be found.
You may also get this exception if an unmanaged dependency or internal
module of the assembly failed to load. Try running depends.exe on the
file to verify that unmanaged dependencies can be loaded. Note that if
you re using ASP.NET, the PATH environment variable it's using may
differ from the one the command line uses. If all of them could be
loaded, try ildasm.exe on the file, double-click on "MANIFEST" and
look for ".file" entries. Each of those files will need to be in the
same directory as the manifest-containing file.

Can't load assembly at runtime

I'm working with a 3rd party assembly to implement something in our in-house software. I can make the refence and work with the library without a problem, but when I run the program to test it i'm getting this error
"Can't load file or assembly "assembly file" nor either of its dependencies. The system couldn't find the specified file" (i'm from Mexico, exception is in Spanish so i had to tanslate it, sorry for the poor translation)
I have given read and write permission to the file, the folder, and for all users and still wont load it.
I saw that the assembly has the PublicKeyToken=null, does that have any to do with that i cant load the assembly????
I already asked the people who developes this assembly, but i'm not getting any response and I really wanna get this project finished
If this is a web application, is the DLL in the bin folder? If it is a deskop application, is it in the same directory as the executable? If not, you may need to set the "Copy Local" attribute on the dll to true in Visual Studio.
Assembly Binding Log Viewer:
The Assembly Binding Log Viewer displays details for assembly binds. This information helps you diagnose why the .NET Framework cannot locate an assembly at run time.
Plus to what Chris said, you have to ensure that if the 3rd party dlls need any other dlls then they must be also in the bin directory, (you can check this by looking at the original directory of the 3rd party dlls and copy all dlls that come with it)

vb.net: how do i build to just one file?

i did a build in vb.net and got one exe file
however, when a user runs the file, it says it is missing one of the libraries (itextsharp).
so the question is, if there is actually a build option in vb.net, why does it not include the library in the same exe file?
You can distribute the iTextSharp DLL with your application. The easiest way to do this is to simply include it in the same folder as your EXE. The DLL should be output to your Project's Debug/Release folder each time you build assuming you've added it as a Reference in your project and the Reference's 'Copy Local' property is set to True.
If you want to distribute one EXE and include the iTextSharp in that, you can use the ILMerge tool (or alternately Gilma from SourceForge) after you build your EXE.
in the properties for the reference set the Copy To Output to Always
ITextSharp is not a library linked in your project output; it's an assembly referenced by your project output. And while VB.Net builds one executable from your source code, the CLR still needs all the referenced assemblies in the same folder as your executable.
To make everything work, you can distribute ITextSharp assemblies along with your app. Alternatively, if you indeed need only one file, you can use ILMerge on your project output and the assemblies you want included. However, you might need to determine all the correct assemblies you need merged. I wouldn't revommend using this tool, unless you understand how it works.
Note: If you want to use ILMerge with .Net v4.0, read this page.
