@lliill Is it possible for you to share the contents of classes.csproj? Thanks!

[lliill]

@rchande

@lliill It looks like you might be missing the necessary Build Tools.
Can you try installing .Net Core Build Tools as described here

[lliill]

@akshita31 how can I install the .Net Core Build Tools without VS studio? I have only installed the .Net Core SDK and I didn't find the .Net Core Build Tools in the website. How can I verify if it was installed?

Can you try installing the build tools from the above ?

[lliill]

In fact, I don't really want to install vs studio....
