CodeDomProvider.CreateCompiler() is obsolete fix

[Andrus]

In code below line

ICodeCompiler loCompiler = new CSharpCodeProvider().CreateCompiler();

in .net 2 causes warning

'System.CodeDom.Compiler.CodeDomProvider.CreateCompiler()' is obsolete:
'Callers should not use the ICodeCompiler interface and should instead use
the methods directly on the CodeDomProvider class. Those inheriting from
CodeDomProvider must still implement this interface, and should exclude this
warning or also obsolete this method.'

How to rewrite code so that warning does not appear ?

code is:

ICodeCompiler loCompiler = new CSharpCodeProvider().CreateCompiler();
CompilerParameters loParameters = new CompilerParameters();
loParameters.ReferencedAssemblies.Add("System.Windows.Forms.dll");
loParameters.GenerateInMemory = false;
loParameters.OutputAssembly = "myasm.dll";


CompilerResults loCompiled =
loCompiler.CompileAssemblyFromSource(loParameters, lcCode);

Use the following:

CodeDomProvider provider = CodeDomProvider.CreateProvider("CSharp");
CompilerParameters cp = new CompilerParameters();
cp.ReferencedAssemblies.Add("System.Windows.Forms.dll")
cp.GenerateInMemory = false;
cp.OutputAssembly = "myasm.dll";

CompilerResults result =
provider.CompileAssemblyFromSource(cp, sourceCode);

Orcas beta2 doesnt throw any deprecation warnings
for this snippet .

£ukasz,

thank you.

How to create signed assembly using provider ?
I think I must pass snk file as parameter but how ?

How to create signed assembly using provider ?
I think I must pass snk file as parameter but how ?

First, use the sn.exe tool to generate a keyfile:

$ sn -k someKeyFile.snk

Then, in Your code, add the CompilerOptions setting:

CompilerParameters cp = new CompilerParameters();
cp.ReferencedAssemblies.Add("System.Windows.Forms.dll")
cp.GenerateInMemory = false;
cp.OutputAssembly = "myasm.dll";

cp.CompilerOptions = "/keyfile:someKeyFile.snk";

And then upon compilation, the compiler will embeed
the strong name key file to the assembly therefore
making it (strongly named/)(gac installable).

I create assemblies at runtime.
I think that cp.CompilerOptions = "/keyfile:someKeyFile.snk";
requires to distribute private key as separate file with my application.

How to embed snk file into application as resource and force compiler to use
it from resource
or generate it at runtime ?

Indeed.

How to embed snk file into application as resource and force compiler

Add a new Resource File to the Project, Add the .snk key file to it,
if the Resource File name was "Resource", and the file name was
keyFile.snk, You will get some resource identifier like
Resource.keyFile typed as byte[].

Create a file stream, and write the byte array to it, You'll get
the resource-embeeded key file as a normal disk file, therefore
You'll be able to use it during assembly compilation.

using (FileStream fs = File.Create("keyFile.snk"))
fs.Write(Resource.keyFile, 0, Resource.keyFile.Length);

And then

cp.CompilerOptions = "/keyfile:keyFile.snk"

should work.
