I am trying to use Matab module compiled as .Net assembly in a .Net Core Project, but I receive the following exception:
Unhandled Exception: System.IO.FileNotFoundException: Could not load
file or ass embly 'MWArray, Version=2.17.1.0, Culture=neutral,
PublicKeyToken=e1d84a0da19db8 6f'. The system cannot find the file
specified. at ConsoleAppCore1._1.Program.Main(String[] args)
MCR_R2017b_win64_installer.exe is installed on the system and I am able to load same Matlab module in .Net4.5 project.
Any clue to make it work with .Net Core1.1?
Simply NO - mathworks supports only "classic"/desktop .net framework on Windows platforms
Please refer to this: mathworks doc

I am trying to port 6 class libraries developed under .Net 4.5.2 to .Net 5.00 using VS 2019. I chose .Net 5.00 (and VS 2019) as my final goal is to deliver the solution as a web assembly. I have set the target framework for each of the libaries to .NET 5.0.
One of my class libraries uses Winforms so I have downloaded the Nuget package Winforms.Wasm (1.0.191137.60) by Roozbeh Gh into VS 2019.
On building I initially got the error:
1>C:\Users\howar_000\.nuget\packages\winforms.wasm\1.0.19137.60\build\netstandard2.0\Winforms.Wasm.targets(13,5): error :
Unhandled Exception: Mono.Cecil.AssemblyResolutionException: Failed to resolve assembly: 'System.Windows.Forms, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'
... at Mono.Cecil.BaseAssemblyResolver.Resolve(AssemblyNameReference name, ReaderParameters parameters)
... at Driver.Import(String ra, AssemblyKind kind)
... at Driver.Run(String[] args)
... at Driver.Main(String[] args)
I was able to get past this problem by adding:
<PropertyGroup>
<CopyLocalLockFileAssemblies>true</CopyLocalLockFileAssemblies>
</PropertyGroup>
as per instructions I found on the Winforms.Wasm GIT repository recommended by Roozbeh Gh.
1>C:\Users\howar_000\.nuget\packages\winforms.wasm\1.0.19137.60\build\netstandard2.0\Winforms.Wasm.targets(13,5): error :

i.e. it just moved the problem along to another library distributed along with Winforms.Wasm. I have also tried to explicitly exclude the Nuget version of the System.Formats.Asn.dll but this hasnt worked either.
I realise the problem is that the Nuget Winforms.Wasm package includes netstardard2.0 libraries so that the package download is as a complete standalone distribution. Further that VS 2019 MSBuild is identifying a clash with the dotnet net5.0 distribution.
I have done a lot of investigation trying to resolve this problem - even overwriting
C:\Program Files\dotnet\packs\Microsoft.NETCore.App.Ref\5.0.0\ref\net5.0\System.Formats.Asn1.dll
with
C:\Users\howar_000.nuget\packages\system.formats.asn1\5.0.0\lib\netstandard2.0\System.Formats.Asn1.dll
and visa versa but to no avail.
But reading through swathes of literature on the web, I came to the realisation that this is a recurring problem that has plagued developers trying to use VS with .Net and Nuget packages for some time. Surely either Microsoft need to change the implementation of VS MSBuild to accommodate Nuget packages or Nuget package writers need to come up with a VS compliant distribution - rather than leaving developers spending many hours trying to establish work arounds and understand the inner works of VS MSBuild.
I am thinking of moving away from VS 2019 to use the Mono Developer toolkit - I will let you know how I get on.
Any help/suggestions on how best to migrate .Net 4.5.2 assemblies that use Nuget packages to equivalent web assemblies would be much appreciated.
I am new to use the DB2. I have added a reference for IBM.Data.DB2 DLL. The Path of the DLL is from X86 directory and also the Local Copy is set to False.
I am using the VisualStudio 2015 with the debug property of is set for x86.
I am able to build the project successfully, but getting following runtime error:
Server Error in '/' Application.
Could not load type 'IBM.Data.DB2Types.DB2DynArray' from assembly 'IBM.Data.DB2, Version=9.7.4.4, Culture=neutral, PublicKeyToken=7c307b91aa13d208'.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.TypeLoadException: Could not load type 'IBM.Data.DB2Types.DB2DynArray' from assembly 'IBM.Data.DB2, Version=9.7.4.4, Culture=neutral, PublicKeyToken=7c307b91aa13d208'.
Let me know if anyone can help me on it or need any other details to investigate it.
If your code explicitly uses the class DB2DynArray , it looks like IBM removed that class from Db2 starting from V9.7 (i.e. DB2DynArray was available in versions up to V9.5 only).
Note that Db2-LUW V9.5 and V9.7 are no longer supported by IBM (current Db2 for Linux/Unix/Windows version is V11.x).
Consider an alternate solution unless the risks of running an unsupported version are signed-off by the business.
IBM registration is required to download Db2-versions(including fixpack) from this site.
Converting VB code from XNA 3.1 to MonoGame.
Any attempt to access class GraphicsAdapter throws the exception below. For example, trying to enumerate GraphicsAdapters. On this line:
For Each adapter As GraphicsAdapter In GraphicsAdapter.Adapters
Result is an exception:

The project references these assemblies (among others):
MonoGame.Framework version=3.6.0.1625
from NuGet "MonoGame.Framework.WindowsDX", file
packages\MonoGame.Framework.WindowsDX.3.6.0.1625\lib\net40\MonoGame.Framework.dll
SharpDX version=4.0.1.0
SharpDX.Direct2D1 version=4.0.1.0
SharpDX.Direct3D9 version=4.0.1.0
SharpDX.DXGI version=4.0.1.0
SharpDX.Mathematics version=4.0.1.0
So I don't see why it would fail this way.
What could be wrong? Not compatible with this SharpDX version?
NOTE: These are all up-to-date packages from NuGet, in Visual Studio 2015. Targeting .Net 4.5.2.
UPDATE
To prove it isn't a problem with SharpDX, I put this line before that GraphicsAdapter line:
Dim testRect As SharpDX.Rectangle = New Rectangle()
This successfully created testRect. No Exception until attempt to access GraphicsAdapter. Also tried all the other Shared (static) properties of GraphicsAdapter, such as GraphicsAdapter.DefaultDevice. Any one fails with same exception.
I posted the same question to MonoGame forums:
http://community.monogame.net/t/solved-typeinitializationexception-accessing-graphicsadapter-adapters-could-not-load-type-sharpdx-rectangle/9803
Cause of problem:
Current release of MonoGame.Framework for WindowsDX (Windows OS + DirectX drivers), 3.6.0.1625 is built against SharpDX 2.6.3, and is not compatible with more recent SharpDX versions.
(Interim) Solution:
The developer branch of MonoGame does target the current SharpDX. Builds can be obtained from MonoGame's teamcity (free registration required).
Tested MonoGame.Framework build 3.7.0.994; it worked with SharpDX 4.0.1:
http://teamcity.monogame.net/viewLog.html?buildId=56483&tab=artifacts&buildTypeId=MonoGame_PackagingWindows
That build installs most SharpDX dlls to
C:\Program Files (x86)\MonoGame\v3.0\Assemblies\Windows
However, SharpDX.Mathematics.dll is currently missing,
so I still install SharpDX from NuGet, rather than using those.
Standard location for MonoGame releases:
(look for at least 3.7, which is not there yet, as I write this):
http://www.monogame.net/downloads/
(If instead of NuGet packages for MonoGame and SharpDX, I had downloaded MonoGame 3.6 installer and used its version of SharpDX dlls at C:\Program Files (x86)\MonoGame\v3.0\Assemblies\Windows, then I would not have had this incompatibility. However, that was not recent enough SharpDX for my purposes. This should be resolved by release of MonoGame 3.7)
I'm trying to implement Universal Windows Platform application with EntityFramework and SQLite (according to: http://ef.readthedocs.org/en/latest/platforms/uwp/getting-started.html) but I have problem with Add-Migration command.
Here is my setup:
Visual Studio 2015 Update 1
EntityFramework.SQLite: "7.0.0-rc1-final"
Error that I got while adding migrations is:
Could not load file or assembly 'System.Collections.Immutable, Version=1.1.36.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)
Thanks in advance for your help!
It is clearly that you miss a dll "System.Collections.Immutable, Version=1.1.36.0" in your project.
To solve this problem, you can open the Nuget tool, and search for System.Collections.Immutable, then in the "Version" label select the Version 1.1.36, by default it is the latest version 1.1.37.
You can also try to update your VS tool, this possible may also solve your problem.
I'm trying to run NUnit v3 alpha from command line. Here's my command line:
[...] \NUnit3\nunit-console NUnitAlpha3Experimental.exe /framework:net-4.5
At first, I got this error:
Errors and Failures Could not load file or assembly 'nunit.framework,
Version=3.0.5378.31152, Culture=neutral,
PublicKeyToken=2638cd05610744eb' or one of its dependencies. This
assembly is built by a runtime newer than the currently loaded runtime
and cannot be loaded.
Then I edited nunit-console.exe.config to comment .net 2.0
<startup useLegacyV2RuntimeActivationPolicy="true">
<!-- Comment out the next line to force use of .NET 4.0 -->
<!--<supportedRuntime version="v2.0.50727" />-->
<supportedRuntime version="v4.0.30319" />
</startup>
I tried these command line (with 4.0 and with 4.5)
[...] \NUnit3\nunit-console NUnitAlpha3Experimental.exe /framework:net-4.0
[...] \NUnit3\nunit-console NUnitAlpha3Experimental.exe /framework:net-4.5
Here's the error message I get:
Errors and Failures Could not load file or assembly 'nunit.framework,
Version=3.0.5378.31152, Culture=neutral,
PublicKeyToken=2638cd05610744eb' or one of its dependencies. The
located assembly's manifest definition does not match the assembly
reference. (Exception from HRESULT: 0x80131040)
Then I tried to edit nunit-console.exe.config to add a new entry for .net 4.5. I tried 4.5, 4.5.1, 4.5.50710, 4.5.50938, 4.5.50932, 4.5.51641 (all of them are present in control panel -> program and features) and I get a windows popup asking me to install .Net framework 4.5.
Edit: The new entry for .Net framework 4.5* shouldn't work anyways. The unit tests do run even if I get the error message. More info here: https://github.com/nunit/nunit-console/issues/42#issuecomment-58709851
Can someone help me with that? Thank you.
It looks like the problem was due to many versions of the dll included with nunit 3.0 (one of each .net framework version) and how it was made available to my assembly. More info here: https://github.com/nunit/nunit-console/issues/42#issuecomment-58713975
