missing version.txt for build process

[HVinther]

I'm unable to build the latest release on Fedora 42. Following the Build on PC / Installation instruction I have installed the dotnet 8.0 sdk and added the nbgv package.

Though when I try to build the package using the listed command I get the following error:

dotnet build --version-suffix 1.0.3.20886 -o bin
MSBuild version 17.8.22+bfbb05667 for .NET
/home/hans/Projekter/cyz2json/Directory.Build.props(3,5): error MSB4184: The expression "[System.IO.File]::ReadAllText(/home/hans/Projekter/cyz2json/version.txt)" cannot be evaluated. Could not find file '/home/hans/Projekter/cyz2json/version.txt'. [/home/hans/Projekter/cyz2json/Cyz2Json/Cyz2Json.csproj]

Build FAILED.

I tried to create a version.txt file by nbgv get-version > version.txt but this causes nbgv get-version to fail.

This might simply be down to me being unfamiliar with the dotnet framework.

I have now tried

nbgv get-version > version2.txt
mv version2.txt version.txt

And then running the build command with the following result

dotnet build -o bin
MSBuild version 17.8.22+bfbb05667 for .NET

So after searching for version in https://learn.microsoft.com/en-us/dotnet/core/tools/dotnet-build it seems this is down to my inexperience with this framework.

So using the Version number returned by nbgv get-version in dotnet build -o bin -p:Version= ... did result in a successful build process. Perhaps you could consider clarifying the build instructions, such that this becomes easier for someone less knowledgeable of dotnet.

[HVinther]

Consider adding something like,

dotnet build -o bin -p:Version="$(nbgv get-version | awk -F"[ ',]+"  '/Version:/{print $2}* )" 

as a build instruction.
