System.IO.FileNotFoundException: 'Could not load file or assembly '.MyProject.XmlSerializers.dll'. The system cannot find the file specified.'

I have generated JAX-RPC SOAP web service proxy with Visual Studio 2019. When I call a service method I got following exception at runtime:

```C#
System.IO.FileNotFoundException: 'Could not load file or assembly 'PathToProject\MyProject.XmlSerializers.dll'. The system cannot find the file specified.'
```

I also tried `Generate Serialization Assembly` from `Properties->Build`, when I change the value to `On` I got build error:
```
An attempt was made to load an assembly with an incorrect format: C:\Program Files\dotnet\packs\Microsoft.NETCore.App.Ref\3.1.0\ref\netcoreapp3.1\Microsoft.VisualBasic.Core.dll.
MyProject PathToMyProject\MyProject \SGEN 1
```
Here is my `csproj` file:

```

Exe
netcoreapp3.1

On

```
And the output of `dotnet --info`:
```
