you need a opening for the <ItemGroup> to wrap the package references

Pobiega•10mo ago

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>net8.0</TargetFramework>
    <ImplicitUsings>enable</ImplicitUsings>
    <Nullable>enable</Nullable>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="restsharp" Version="110.2.0" />
  </ItemGroup>

</Project>

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>net8.0</TargetFramework>
    <ImplicitUsings>enable</ImplicitUsings>
    <Nullable>enable</Nullable>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="restsharp" Version="110.2.0" />
  </ItemGroup>

</Project>

this should be all you need a correct version for restsharp, no invalid NuGet reference

slicybtwOP•10mo ago

ok thanks its fixed i have a question

Pobiega•10mo ago

feel free to ask

slicybtwOP•10mo ago

how can i turn the Program.cs file to .exe

Pobiega•10mo ago

well you're on linux, so you just mean an executable file ye? not specifically .exe, which is for windows

slicybtwOP•10mo ago

i want to test it on windows

Pobiega•10mo ago

then I think you might have to build it on a windows machine regardless, you're looking for dotnet publish, but it has tons of optional switches that configure how it works

slicybtwOP•10mo ago

ok, thanks
