Nop.Data.dll could not be found ERROR W7 - 4.20 - VS2019 - ASP.NET -

Hey guys,

try to install nop 4.20 for my local machine.
My system:
- Windows 7
- Visual Studio 2019 (16.4.5)
- ASP.NET
- .NET Core 2.2 Runtime (EOL)
- .NET Core 3.1 SDK
- Live Share
- Just-in-Time-Debugger

Error message CS0006 after click on IIS Express:

Error  CS0006  Metadata file 'D:\NOOP_COMMERCE\src\Libraries\Nop.Data\bin\Debug\netcoreapp2.2\Nop.Data.dll' could not be found

Error  CS0006  Metadata file 'D:\NOOP_COMMERCE\src\Libraries\Nop.Services\bin\Debug\netcoreapp2.2\Nop.Services.dll' could not be found

Error  CS0006  Metadata file 'D:\NOOP_COMMERCE\src\Presentation\Nop.Web.Framework\bin\Debug\netcoreapp2.2\Nop.Web.Framework.dll' could not be found

What i forget to install? I want to test nop for the first on a local machine.

Thanks

Tibor

Might be a silly question but did you build the solution ?

Hello Yidna,

no, is there a guide how can i build the solution?

Open solution in Visual Studio
Click Build and Build Solution in the Top Menu
Or if you are not planning to change the code use the no-Source version

Use the No Source Binaries directly if you are not a developer.

Thanks. After that, the same error. I need the version with source code.  I see the nop 4.20 with source have a size of only 33,8 MB, maybe there is missing data?

Hi, with the 3.9 source code version is running. (around 112 MB)
The newer versions don't work. Possibly, the file is not complete (only 30-35 MB in size)

It’s not the problem at all. Try to build project in Visual Studio and make sure build is success.

when try to build nopCommerce_4.30_Source with VS 2019 it say:
Error  CS0006  Metadata file 'D:\my.net\nopCommerce_4.30_Source\Libraries\Nop.Data\bin\Debug\netcoreapp3.1\Nop.Data.dll' could not be found

In the Visual Studio's top menu did you do Build > Build Solution?
