Give a better error with Swashbuckle.AspNetCore.Cli when there is .dll version mismatch

[mcraiha]

If one uses dotnet tool to install Swashbuckle.AspNetCore.Cli and the actual project uses different version of Swashbuckle.AspNetCore.Swagger.dll (e.g. 6.5.0 vs 6.4.0) you will get error like

Unhandled exception. System.IO.FileLoadException: Could not load file or assembly 'Swashbuckle.AspNetCore.Swagger, Version=6.0.7.0, Culture=neutral, PublicKeyToken=62657d7474907593'. The located assembly's manifest definition does not match the assembly reference. (0x80131040)
File name: 'Swashbuckle.AspNetCore.Swagger, Version=6.0.7.0, Culture=neutral, PublicKeyToken=62657d7474907593'
   at Swashbuckle.AspNetCore.Cli.Program.<>c.<Main>b__0_3(IDictionary`2 namedArgs)
   at Swashbuckle.AspNetCore.Cli.CommandRunner.Run(IEnumerable`1 args) in C:\projects\ahoy\src\Swashbuckle.AspNetCore.Cli\CommandRunner.cs:line 68
   at Swashbuckle.AspNetCore.Cli.CommandRunner.Run(IEnumerable`1 args) in C:\projects\ahoy\src\Swashbuckle.AspNetCore.Cli\CommandRunner.cs:line 59
   at Swashbuckle.AspNetCore.Cli.Program.Main(String[] args) in C:\projects\ahoy\src\Swashbuckle.AspNetCore.Cli\Program.cs:line 111

but it would be better to tell the use that there is a version mismatch.

So something like:

Swashbuckle.AspNetCore.Cli version 6.5.0 cannot process %path%/Swashbuckle.AspNetCore.Swagger.dll because it is based on version 6.4.0 and both versions must match!

You could suggest that any tool write custom exception messages to handle mismatched dependency versions in any combination.

This isn't worth us maintaining custom support for.
